MODEM COMMUNICATIONS WITH THE T1 AND T2E/T2N
March 1998
USING T-PDS WINDOWS FOR DIAL–UP COMMUNICATIONS WITH TOSHIBA
T1 AND T2E/T2N PROGRAMMING PORT
Toshiba PLC users can expand their remote diagnostics and remote programming capabilities
by using Hayes compatible modem communications over the Public Switched Telephone
Network with standard analog phone lines and standard modems. Please note that “analog” line
means a normal dial-in dial–out phone line similar to the ones that you have at home (i.e., about
48Vdc open circuit voltage with about 110Vac ring voltage). This does
not
include the digital
phone lines in
most offices
that use modern digital PBX systems. Plugging a modem directly into
one of these digital office lines may destroy the modem.
We used US Robotics 56K Sportster external modems for our tests, but just about any external
Hayes compatible modem will work. Here is the list of equipment that you need for modem
communications with the PLC’s programming ports:
Accessories For T2E/T2N Modem Communications (with programming port):
PC Side
:
a standard “straight-through” 9-25 pin RS-232 serial cable
a 9600 baud external modem.
PLC Side
:
a standard “straight-through” 9-25 pin RS-232 serial cable
a 9600 baud external modem.
