Internal BERT B-5
For more detailed information on BERT commands, refer to the CM601
Reference Guide.
BERT Usage Check Pattern Types
If the CM601 is transmitting to another CM601, ensure that the pattern type
matches 2
9
-1. If needed, modify the pattern type. Do this from either the:
Remote terminal by issuing the BPT (BERT pattern type) command.
Front panel by:
a. Scrolling through the BConfig command list until the display reads
BERT Pattern xxxx
where
xxxx
represents the current pattern.
b. To modify the pattern type, scroll through the parameter options until the
desired pattern option appears on the display. Press the Enter button.
