RS232/RS-485 Communications Converter - QD1010b

• Once a network is wired, you should test communi-

cations with all controllers on the network. Find out

which controllers communicate and which ones don't.

Go to the controllers that don't communicate and ver-

ify that the "A" and "B" wires are not switched. Verify

the address and the baud rate as well. One of these

three things is usually the problem. (see chart below)

THEN

Check that the baud rate set on the controller(s) are

all set the same. Verify controller address.

Rx LED is always on. This is typically a problem with wir-

ing.

Check wiring. Make sure that communication wir-

ing runs are at least 5' away from fluorescent lights,

motors, etc. Make sure that all controllers on a net-

work have a unique address.

Make sure that the "A" and "B" wires are not switched

or shorted. Make sure that there is no stray voltage

on the "A" and "B" wires. "B" to "A" should measure

between 0.5 VDC and 3.6 VDC. "B" to "A" should

measure 0 VAC. "A" to "Shield" and "B" to "Shield"

should measure 0 VAC and 0 VDC.

Both Tx and Rx LEDs will blink. Both the computer and the

controller are responding, but you still receive communica-

tion errors.

Tx LED blinks, Rx LED is always off. If this happens, the

computer is sending, but the controller is not responding.

On smaller networks, try removing one of the two ter-

minating resistors.

Communication errors/problems.
