Troubleshooting Tips

Symptom

Check/Action

Serial Communications METER LINK
LED Indicator is off

Check:

1. Modular cable connection
2. Power to the device

If only the TX (or DATA IN) data status
LED is flashing when serial
communications attempted

Check:

1. Serial cable
2. Instrument address & baud rate
3.

Program address & baud rate

If both data status LEDs (TX and RX)
are off when trying to communicate

Remove all unnecessary cables and instruments from the bus.
Try getting the system to work with only one device (to ease
troubleshooting) and then expand the system one device at a time.

Communications slow

Increase the baud rate

Random communication errors

1. Increase the TX delay time
2. Decrease the baud rate

Other symptoms not described above

Call Technical Support for assistance

Note:

Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory

defaults and use the manual as a step by step programming guide, rather than a random approach to programming. To reset the
meter to factory defaults, see

Reset Meter to Factory Defaults

on page

In addition, for best results, we recommend using the

free MeterView Pro software for all programming needs.
