4 SETTINGS AND PROCEDURES PRIOR TO OPERATION

(b) Do not use the above settings for the following cases, because linked

operation cannot be performed.

1) When using the QJ71C24N-R2 or QJ71C24-R2.

2) When an external device is not connected to either of the interfaces.

3) When the bidirectional protocol is used for data communication.

4) When communicating data with an external device connected to two

interfaces that are not interacting, using functions set in the

communication protocol settings (MC protocol/non procedure protocol).

5) When communicating data using the modem function.

POINT

When two interfaces are in linked operation, the transmission time for one

character becomes equal to the hardware gate off time of the Q series C24.

1) Two interfaces operate linked together using functions defined with the

communication protocol setting on the CH2 side (MC protocol in the

same format or a non procedure protocol) within the transmission

specifications set in the respective transmission settings (specifications

for CH1 and CH2 must be the same).
