(latest update May 29, 1997)
|
||||
|
||||
The TW523 is a carrier-current modem for home control/automation purposes.
|
||||
It is made by:
|
||||
|
||||
X-10 Inc.
|
||||
185A LeGrand Ave.
|
||||
Northvale, NJ 07647
|
||||
USA
|
||||
(201) 784-9700 or 1-800-526-0027
|
||||
|
||||
X-10 Home Controls Inc.
|
||||
1200 Aerowood Drive, Unit 20
|
||||
Mississauga, Ontario
|
||||
(416) 624-4446 or 1-800-387-3346
|
||||
|
||||
The TW523 is designed for communications using the X-10 protocol,
|
||||
which is compatible with a number of home control systems, including
|
||||
Radio Shack "Plug 'n Power(tm)" and Stanley "Lightmaker(tm)."
|
||||
I bought my TW523 from:
|
||||
|
||||
Home Control Concepts
|
||||
9353-C Activity Road
|
||||
San Diego, CA 92126
|
||||
(619) 693-8887
|
||||
|
||||
They supplied me with the TW523 (which has an RJ-11 four-wire modular
|
||||
telephone connector), a modular cable, an RJ-11 to DB-25 connector with
|
||||
internal wiring, documentation from X-10 on the TW523 (very good),
|
||||
an instruction manual by Home Control Concepts (not very informative),
|
||||
and a floppy disk containing binary object code of some demonstration/test
|
||||
programs and of a C function library suitable for controlling the TW523
|
||||
by an IBM PC under MS-DOS (not useful to me other than to verify that
|
||||
the unit worked). I suggest saving money and buying the bare TW523
|
||||
rather than the TW523 development kit (what I bought), because if you
|
||||
are running FreeBSD you don't really care about the DOS binaries.
|
||||
For details on the X-10 protocol itself, refer to the documentation from
|
||||
X-10 Inc.
|
||||
|
||||
The interface to the TW-523 consists of four wires on the RJ-11 connector,
|
||||
which are jumpered to somewhat more wires on the DB-25 connector, which
|
||||
in turn is intended to plug into the PC parallel printer port. I dismantled
|
||||
the DB-25 connector to find out what they had done:
|
||||
|
||||
Signal RJ-11 pin DB-25 pin(s) Parallel Port
|
||||
Transmit TX 4 (Y) 2, 4, 6, 8 Data out
|
||||
Receive RX 3 (G) 10, 14 -ACK, -AutoFeed
|
||||
Common 2 (R) 25 Common
|
||||
Zero crossing 1 (B) 17 or 12 -Select or +PaperEnd
|
||||
|
||||
NOTE: In the original cable I have (which I am still using, May, 1997)
|
||||
the Zero crossing signal goes to pin 17 (-Select) on the parallel port.
|
||||
In retrospect, this doesn't make a whole lot of sense, given that the
|
||||
-Select signal propagates the other direction. Indeed, some people have
|
||||
reported problems with this, and have had success using pin 12 (+PaperEnd)
|
||||
instead. This driver searches for the zero crossing signal on either
|
||||
pin 17 or pin 12, so it should work with either cable configuration.
|
||||
My suggestion would be to start by making the cable so that the zero
|
||||
crossing signal goes to pin 12 on the parallel port.
|
||||
|
||||
I use the TW-523 and this software in the USA with 120V/60Hz power.
|
||||
Phil Sampson (vk2jnt@gw.vk2jnt.ampr.org OR sampson@gidday.enet.dec.com)
|
||||
in Australia has reported success in using a TW-7223 (a local version
|
||||
of the TW-523) and Tandy modules with this software under 240V/50Hz power.
|
||||
For reasons explained in the comments in the driver, it will probably not
|
||||
work if you have three-phase power, but this is usually not the case for
|
||||
normal residences and offices.
|
||||
|
||||
|
||||
1. Installing the TW523 Device Driver
|
||||
|
||||
I assume that you are running FreeBSD. If you are running some other
|
||||
system, you are more or less on your own, though I can try to help if you
|
||||
have problems.
|
||||
|
||||
Check the configuration parameters at the beginning of the file
|
||||
|
||||
/sys/i386/isa/tw.c
|
||||
|
||||
Probably the only thing you might need to change is to change the
|
||||
definition of HALFCYCLE from 8333 to 10000 if you are using 50Hz power.
|
||||
The driver assumes that the TW523 device is connected to a parallel port.
|
||||
See the comments near the beginning of the file to find out where to
|
||||
get a TW523 if you don't have one, and how to make a cable for it to
|
||||
connect to your parallel port.
|
||||
|
||||
Add a line like the following
|
||||
|
||||
device tw0 at isa? port 0x278 tty irq 5
|
||||
|
||||
to /sys/i386/conf/YOURSYSTEM, but make sure to change the I/O port and
|
||||
interrupt to match your hardware configuration.
|
||||
|
||||
Cd to /sys/i386/conf and do "config YOURSYSTEM".
|
||||
Cd to /sys/compile/YOURSYSTEM and do "make depend", then "make".
|
||||
(If you have any troubles, I suggest starting fresh by doing a full
|
||||
"make clean; make depend; make".) Assuming the make works correctly, do
|
||||
|
||||
make install
|
||||
|
||||
(Take the usual precautions by saving a known working kernel until you
|
||||
verify that the new kernel actually boots.)
|
||||
|
||||
Reboot the system. You should see a line indicating that the TW523 has
|
||||
been configured as the system comes up. If you see this line, then probably
|
||||
everything is going to work OK, because the TW523 will only get configured
|
||||
if the driver is able to sync to the power line. If the TW523 is not plugged
|
||||
in, or the driver is not getting sync for some reason, then you won't see
|
||||
any message on bootup.
|
||||
|
||||
NOTE: I have received a report that some multi IDE/SIO/PARALLEL cards
|
||||
"cheat" and use TTL outputs rather than pullup open collector outputs,
|
||||
and this can mess up the scheme by which sync gets to the driver.
|
||||
If you are having trouble getting the driver to work, you might want to
|
||||
look into this possibility.
|
||||
|
||||
In directory /dev, execute the command
|
||||
|
||||
MAKEDEV tw0
|
||||
|
||||
|
||||
2. Installing the X-10 Daemon
|
||||
|
||||
The X-10 daemon "xtend" is integrated in to the FreeBSD "/etc/sysconfig"
|
||||
system configuration file. To enable the daemon, simply edit that file,
|
||||
find the "xtend" line, change it to read as below.
|
||||
|
||||
# Set to YES if you want to run the X-10 power controller daemon
|
||||
xtend=YES
|
||||
|
||||
This will cause the X-10 daemon to be invoked automatically when you boot
|
||||
the system. To test the installation, you can either reboot now, or
|
||||
you can just run "xtend" by hand. The daemon should start up, and it should
|
||||
create files in /var/spool/xten. Check the file /var/spool/xten/Log to
|
||||
make sure that the daemon started up without any errors.
|
||||
|
||||
Now you are ready to start trying X-10 commands. Try doing
|
||||
|
||||
xten A 1 Off
|
||||
xten A 1 On 1 Dim:10
|
||||
|
||||
etc. The "xten" program expects a house code as its first argument, then
|
||||
a series of key codes, which are either unit names ("1" through "16") or
|
||||
else are command names. You can find the list of command names by looking
|
||||
at the table in the file "xten.c". Each key code can optionally be followed
|
||||
by a colon : then a number specifying the number of times that command is
|
||||
to be transmitted without gaps between packets. The default is 2, and this
|
||||
is the normal case, but some commands like Bright and Dim are designed to
|
||||
be transmitted with counts other than 2. See the X-10 documentation for
|
||||
more detail.
|
||||
|
||||
The "xten" program works by connecting to "xtend" through a socket, and
|
||||
asking that the X-10 codes be transmitted over the TW523. All activity
|
||||
on the TW523 is logged by the daemon in /var/spool/xten/Log. The daemon
|
||||
also attempts to track the state of all devices. (Of course, most X-10
|
||||
devices do not transmit when they are operated manually, so if somebody
|
||||
operates a device manually there is no way the X-10 daemon will know
|
||||
about it.)
|
||||
|
||||
3. Low-level Programming of the TW523 Driver
|
||||
|
||||
Normally, you would never operate the TW523 directly, rather you would
|
||||
use the shell command "xten" or you would connect to "xtend" through its
|
||||
socket. However, if you don't want to run "xtend", you can manipulate
|
||||
the TW523 directly through the device /dev/tw0. Have a look at the
|
||||
xtend code for a programming example.
|
||||
|
||||
The driver supports read(), write(), and select() system calls.
|
||||
The driver allows multiple processes to read and write simultaneously,
|
||||
but there is probably not much sense in having more than one reader or more
|
||||
than one writer at a time, and in fact there may currently be a race
|
||||
condition in the driver if two processes try to transmit simultaneously
|
||||
(due to unsynchronized access to the sc_pkt structure in tw_sc).
|
||||
|
||||
Transmission is done by calling write() to send three byte packets of data.
|
||||
The first byte contains a four bit house code (0=A to 15=P). The second byte
|
||||
contains five bit unit/key code (0=unit 1 to 15=unit 16, 16=All Units Off
|
||||
to 31 = Status Request). The third byte specifies the number of times the
|
||||
packet is to be transmitted without any gaps between successive transmissions.
|
||||
Normally this is 2, as per the X-10 documentation, but sometimes (e.g. for
|
||||
bright and dim codes) it can be another value. Each call to write can specify
|
||||
an arbitrary number of data bytes, but at most one packet will actually be
|
||||
processed in any call. Any incomplete packet is buffered until a subsequent
|
||||
call to write() provides data to complete it. Successive calls to write()
|
||||
leave a three-cycle gap between transmissions, per the X-10 documentation.
|
||||
The driver transmits each bit only once per half cycle, not three times as
|
||||
the X-10 documentation states, because the TW523 only provides sync on
|
||||
each power line zero crossing. So, the driver will probably not work
|
||||
properly if you have three-phase service. Most residences use a two-wire
|
||||
system, for which the driver does work.
|
||||
|
||||
Reception is done using read(). The driver produces a series of three
|
||||
character packets. In each packet, the first character consists of flags,
|
||||
the second character is a four bit house code (0-15), and the third character
|
||||
is a five bit key/function code (0-31). The flags are the following:
|
||||
|
||||
#define TW_RCV_LOCAL 1 /* The packet arrived during a local transmission */
|
||||
#define TW_RCV_ERROR 2 /* An invalid/corrupted packet was received */
|
||||
|
||||
The select() system call can be used in the usual way to determine if there
|
||||
is data ready for reading.
|
||||
|
||||
|
||||
Happy Controlling!

Hi,

I have just verified that /dev/tw works on 2.1.0-RELEASE. I can
|
||||
send and receive x10 commands via my x10 daemon and X11 based tools.
|

I used a "cross-over" cable between tw523 and db-25 connector:

|

|

Be sure that the tw523 is NOWHERE NEAR a surge protector. I have seen
|

x-10 devices fail to work when plugged in NEXT to a surge protector!
|
||||
|

|

I placed the tw option before the lpt entries in my config file:
|

|
||||
device tw0 at isa? port 0x378 tty irq 7
|
||||
device lpt0 at isa? port? tty irq 7
|

from dmesg I get:

|

Dec 9 19:11:59 ilsa /kernel: lpt0 not probed due to I/O address conflict with
|

tw0 at 0x378
|

|

Once I have opened /dev/tw with my daemon I get messages

(pressing UNIT J, key 16):

|

|

These messages from the driver should be dis-abled once you get it working,
|

you'll fill up the var partition with a lot of useless garbage otherwise!

|

|
||||
Hi,
|
||||
|
||||
I now more or less understand the set of problems concerning cabling
|
||||
for using /dev/tw and a tw523. Summary:
|
||||
|
||||
|
||||
1: modular cables come in 2 flavors:
|
||||
|
||||
|||||----------||||| <- "phone" cable
|
||||
\ /
|
||||
|
||||
\
|
||||
|||||----------||||| <- "data" cable
|
||||
\
|
||||
|
||||
we need to be able to clearly differentiate the two. I suggest we
|
||||
standardize on using "phone" cables only.
|
||||
|
||||
|
||||
2: modular db25 connectors ARE NOT CONSISTANT in their color code
|
||||
scheme, EVEN within the same BRAND!
|
||||
|
||||
we can't describe the connection in terms of cable/connector wire color.
|
||||
we must clearly explain the consequences of mis-connection:
|
||||
POSSIBLE damage to (but NOT limited to) the parallel port and/or tw523.
|
||||
|
||||
|
||||
3: not all parallel ports have pullups on their status inputs. I found
|
||||
2 different port boards in my junk box without pullups on paper-out.
|
||||
As is, these boards failed to work, ie the probe routine failed.
|
||||
By adding 10K pullup resistors (to +5v) to both ACK and paper-out
|
||||
(pins 10 & 12) I was able to make these boards work: probe succeeds,
|
||||
transmit and receive work reliably.
|
||||
|
||||
we must describe a test to determine if a parallel port will work as is.
|
||||
perhaps something like:
|
||||
|
||||
--------------------------------------------------------------------------
|
||||
Not a parallel ports will work with the connector described in this paper.
|
||||
To test your port for usability you should take the following measurements
|
||||
with a voltmeter. The computer must be powered-up, and preferably in
|
||||
a safe state for tinkering, such as halted in a startup menu. Nothing
|
||||
should be attached to the parallel ports, except perhaps an extension
|
||||
cable for testing convenience.
|
||||
|
||||
1: measure the voltage between pins 10 & 25 (GND) of the parallel port.
|
||||
|
||||
2: measure the voltage between pins 12 & 25 (GND) of the parallel port.
|
||||
|
||||
If both of these measurements have a value of >= 4.0 volts your port
|
||||
should work as is. If either is below 4.0 volts (typically less than
|
||||
1.0 volt) your port will NOT WORK RELIABLY as is. It can be made to
|
||||
work by adding 10k ohm pull-up resistors to either line that is below
|
||||
the minimum 4.0 volts. This is an ADVANCED TECHNIQUE that should NOT
|
||||
be attempted by anyone without some hardware construction experience.
|
||||
|
||||
Assuming that you do feel competant to make these modifications it is
|
||||
easiest to tack 10k resistors on the bottom side of the port board
|
||||
from each of pins 10 & 12 of the parallel port connector to a source
|
||||
of +5 volts. This will probably be the power pin of one of the ICs.
|
||||
CAUTION: there may also be +-12 volts on a port board supplying some
|
||||
of the ICs. If your port is on your motherboard it would probably be
|
||||
best to obtain an external port card, and disable/re-address the 1st
|
||||
parallel port.

When invoked with a one-letter house code (A-P) and a series of key/unit
|
||||
codes as arguments, it requests the X-10 daemon to transmit a corresponding
|
||||
series of X-10 packets. The X-10 daemon makes its best effort to ensure
|
||||
that the packets are all transmitted correctly, though in general it is
|
||||
not possible to tell whether the commands were actually received and
|
||||
executed by the remote X-10 devices.
|
||||
.Pp
|
||||
When invoked with the single argument
|
||||
.Fl "" ,
|
||||
.Nm
|
||||
enters an interactive mode in which a line is repeatedly read from the
|
||||
standard input, sent to the X-10 daemon, and the one-line response from
|
||||
the daemon printed on the standard output.
|
||||
.Sh OPTIONS
|
||||
The
|
||||
.Ar house
|
||||
argument is a one-letter house code in the range A-P.
|
||||
All the X-10 requests generated will refer to this house code.
|
||||
Each
|
||||
.Ar key
|
||||
is either a numeric unit code in the range 1-16, or else
|
||||
is a string that specifies an X-10 function. The possible
|
||||
function code strings are:
|
||||
.Bl -diag
|
||||
.It AllUnitsOff
|
||||
.It AllLightsOn
|
||||
.It On
|
||||
.It Off
|
||||
.It Dim
|
||||
.It Bright
|
||||
.It AllLightsOff
|
||||
.It ExtendedCode
|
||||
.It HailRequest
|
||||
.It HailAcknowledge
|
||||
.It PreSetDim0
|
||||
.It PreSetDim1
|
||||
.It ExtendedData
|
||||
.It StatusOn
|
||||
.It StatusOff
|
||||
.It StatusRequest
|
||||
.El
|
||||
.Pp
|
||||
Each
|
||||
.Ar key
|
||||
may be followed by an optional numeric
|
||||
.Ar cnt ,
|
||||
which specifies the number of packets that are to be sent with that
|
||||
key code without gaps. If this argument is omitted, two packets
|
||||
are transmitted. The ability to specify numbers of packets other than
|
||||
two is used by the X-10
|
||||
.Em Dim
|
||||
and
|
||||
.Em Bright
|
||||
commands.
