Uni-com UAC-02RS2


Recommended Posts

I connected the Unistream HMI Panel USP-104-B10 with
Uni-com module UAC-02RS2. (2xRS232)
However, the power LED on UAC-02RS2  does not light up or blink.
It's a hardware bug, or I'm doing something wrong.

I use the software Unilogic  version  1.21.51 .
TX RX communication works well on this module.

Does anyone know, how to help me?

We in the project used 
1x UAC-01RS2
2x UAC-02RS2
3x USP-104B10 with 3x USC-P-B10
BUS connectors are well connected.
All modules work correctly, including COM modules.
Data Tx and Rx  in com modules also work.
The only error is that, the power LED on the COM modules does not lighting.
The power LEDs on the I / O modules light up well.

Best regards.
