QJ71C24N/RS422/E100 Connection problems

[stl 0]

Hi, I'm trying to get an E100 Text panel talking via a E-C24-422-CAB cable to Port 2 (RS422) of a QJ71C24N. E-Designer settings are as follows: Driver: QnA/Q C24 Protocol/Q series 3.07.7 Default Parameters: Baud Rate: 19200 Parity None Databits: 8 StopBits: 1 Default Station is 0 GX Developer Switch settings Port 1: Redlion HMI(Data Connection over Rs232) working fine Switch 1:05C6 Switch 2:0001 Port 2: RS422(Not working) Switch 3:0762 Switch 4:0005 The screen is flashing "Comms Error 0" however i cant find any material to expand on this Error!!! Please can someone put me out of my misery - i have wasted two days so far on this. Thanks as always for any assistance Steve Edited 27 Nov 2008 by stl

don't have time to look it up now but if i recall correctly, using one port of C24 is no problem but there maybe restrictions on use of both ports.
