5.15.5 Networking Issues
The most common problems with down loading data are incompatibility between
the PC baud rate settings or wrong RS232/RS485 settings.
5.15.6 Communication ports
Check that the cable is installed on the correct communication port on your PC.
RS232
If you are connected to the RS232 port on your External device, confirm that the
Communications configuration is correct.
Baud Rate: 9600, 19200, 32400, 57600 or 115000
Data bits: 8
Parity: None
Stop Bits: 1
RS485
You should make sure that the RS485 port selected in CoLOS Control, is the
actual Comm port connected on your PC. Typically Com1 on the network card is
Com3 on the PC. Com2 on the network card is Com4 on the PC.
5.15.7 Communications connection
For details of the pin connections please refer to Section 3 - Installation and
Section 12 Electrical Schematics.
5.15.8 Broken wires or shorts
• Check the resistance of the wires to make sure that they are connected
correctly.
• Check all connections for short circuits. This is one of the most common
reasons for the communications to be failing, especially on a network.
