Communication Troubleshooting Checks

No Communications

Possible Cause

Corrective Action

Polarity reversed

Check the wiring for proper polarity. Review associated wiring

diagrams. Correct the wiring.

Address not set correctly

From the Display, check the Address setting.

On the

User Interface

board, check the dip switch settings.

Refer to “Setting the Analyzer Address” in this section for more

information.

Maximum distance be-

tween devices exceeded

If the distance between the Display Unit and the analyzer

(furthest analyzer in a daisy-chain configuration) exceeds 1219.2

meters (4000 ft), the devices must be moved closer together.

Broken connection

Check cables and wiring for damaged or broken connections.

Replace or fix the connections as needed.

Intermittent Communications

Possible Cause

Corrective Action

Poor wiring (i.e., lack of

shielded twisted pair)

Check the wiring to ensure it meets proper specifications for this

installation. Replace the wiring if necessary.

Termination enabled on

more than one unit (on

multi-unit systems)

Check the communication termination resistors (dip switch

SW-5

) on each analyzer in the daisy-chain. This switch is located

on the front of the

Sensor

board. Only the dip switch on the

last analyzer (farthest from the Display Unit should be Enabled.

Ensure all others are Disabled.

Termination not enabled

(on multi-unit systems)
Maximum distance be-

tween devices exceeded

If the distance between the Display Unit and the analyzer (fur-

thest analyzer in a daisy-chain configuration) is close to exceed-

ing, or does exceed, the maximum required distance (1219.2 me-

ters/4000 ft), the devices may need to be moved closer together.
