Things to Know

The following sections provide some information that is very helpful when troubleshooting a

problem.

DMP Feature Codes

All XR series Command Processors™ use a numeric code to access certain features. Some of

these features include on-board programmer menu, diagnostic menu and the walk-test

function.

To make them easy to remember, these codes have a word-equivalent that can be spelled

out using the keys on the keypad.
