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.
