Toshiba T1 manual

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 supports odd parity. This will apply if you have a T1 with firmware version earlier than 1.2, or any of the T2 series that is not a T2E/T2N. Most T3’s will also require an odd parity modem. One source for these modems is TELENETICS, ph: (714)455-4000; fax (714)455-4010. Telenetics model number MIU14.4-11B-9600 should be an appropriate modem to use.

You can use the same configuration methods as shown in this note, just select “Odd” parity Instead of “Non” parity.
