No. 1485 Comunication of CSE-H55N woth Roger PR402DR 2017-04-28

Hello
I have a problem with communication using CSE-H55N with Roger controller PR402DR. I connected your device to controler through RS485 and connected it to my computer by ethernet. Using ezVSP i established virtual port and when i use PR Master to connect to controller i can't find it. When i search link diode on controler and sending diode on your device are blinking but reciving diode is not. What may by the reason of such problem?
