Accessories For T1 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 “null-modem” adapter such as Radio Shack’s 9-9 pin Null Modem • a Toshiba part number TKRS232T1 T1 programming cable • a ≥ 9600 baud external modem. See Note 2 on page 5 Now that we have discussed the basic hardware requirements, let’s look at the

STEP 3: CONFIGURE THE PLC’s MODEM: Now that T-PDS is configured, we are ready for the last part of our setup procedure which is to initialize our remote PLC modem. We suggest that you connect your PC to the PLC’s modem with the straight-through 9-25 pin RS-232 cable, and open up Windows Terminal (or similar). Set up the terminal program for 9600 baud, 8 data bits, 1 stop bit, no parity. Once the terminal connection is opened, you can begin to set the parameters in the PLC’s modem. There are

When the programming port is set to non parity, only the T-PDS software (and the modem) can communicate with the PLC. Furthermore, the T-PDS software must also be setup for non parity. Note 5: For T-PDS versions prior to Ver 1.2 contact Toshiba for upgrade eligibility. A SPECIAL NOTE FOR USERS THAT HAVE OLDER T1’s, T2’s, and T3’s WHOSE PROGRAMMING PORTS DO NOT SUPPORT A “NO-PARITY” SETTING If you have one of these PLCs and would like to use modem communications, you must use a modem that suppor
