Troubleshooting Serial Connections

54 RS232 Control

Global Command to Subsequent Tiles

Open the Serial Port Status menu

on all tiles. Send a global

command from the host.

Do you see one

tile not

responding when

other tiles on the

same Quad Input

Manager Module

do respond?

Your Quad Input Manager

Module may be defective.

Check the RS485 cabling to the

Quad Input Manager Module.

Try a smaller group of Quad

Input Manager Modules. If a

module is bad, it could prevent

any tiles from getting the

message. If you suspect a bad

module, get a small group

working and then add tiles to

the chain one at a time.
