Preparing Communications
Offline Tests in MAINTENANCE Mode
In MAINTENANCE mode, communications between the ID Controller and Data Carriers can be tested
without connecting to the host device.
Use offline testing to check installation positions before performing test operations.
Testing Host Device Communications
The TEST command can be used to test communications between the ID Controller and host device.
This enables checking cable connections and communications processing before testing the operation
of the entire system.

Create a simple communications program on the host device to send the TEST command (TS).
If communications function properly, the ID Controller will send back the received data.
