INVALID DTE SETTINGS
It may be necessary to change certain options on the DTE hardware. Please consult the user’s manual for
your particular DTE hardware to ensure proper setup.

RF ERRORS
RF errors can range anywhere from a non-viable microwave path to loose RF connectors.
Non-viable path conditions could be caused by physical obstructions such as buildings, mountainous
terrain, trees, etc., as well as other physical limitations such as excessive path distances and in-band RF
interference. These types of errors are remedied by performing a detailed line-of-sight microwave path
study to determine whether or not a microwave link is feasible for the terrain and environment under
consideration.

interference. These types of errors are remedied by performing a detailed line-of-sight microwave path
study to determine whether or not a microwave link is feasible for the terrain and environment under
consideration.
If after performing a microwave path study the system is still not operational, ensure that the antennas are
properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link
performance. The TRACER 2210 can be used to aid in antenna alignment by looking at the RSSI
submenu. Optimal antenna alignment will correspond to the maximum number of RSSI asterisks (or bars)
on the 2210 RSSI display.

LOOPBACK OPTIONS
The TRACER 2210/3202 has several data path loopback options available to assist in piece-wise
verification of data path integrity throughout the circuit. Each loopback option can be turned on/off from
the keypad menu on the 2210 unit. Enter the following menu selection to access the Loopback submenu.
