REPEATER OPERATION
ACCESS MODE
Command Form:
(PW) 57 00 (mode 0-5) *
Description:
This command selects one of six possible repeater access modes:
Mode 0 No Access. Activity on the COR and PL inputs is ignored.
Mode 1 Carrier Access. Activity on the COR input keys the transmitter.
Activity on the PL input is ignored.
Mode 2 PL Access. Activity on the PL input keys the transmitter. Activity on
the COR input is ignored.
Mode 3 AND-PL access. Activity on both the COR and PL inputs
simultaneously keys the transmitter.
Mode 4 OR-PL Access. Activity on either the COR or PL inputs keys the
transmitter.
Mode 5 ANTI-PL Access. Activity on the COR input simultaneously with no
activity on the PL input keys the transmitter.
Note: Repeater Access may be made different from DTMF Decoder access
Acknowledgement:
OK
Errors:
? ERR 1
wrong number of digits entered
? ERR 2
illegal digit entered
Default Condition:
Mode 1 (Carrier Access)
Examples:
If the repeater is in carrier access mode, and PL access is desired, enter:
(PW) 57 00 2 *
A better mode for many repeater installations is Mode 3, AND-PL Access.
(This mode has better rejection of adjacent-channel interference than Mode
2, since noise falsing from unsquelched audio is eliminated. Also, COR
drops out more quickly than PL, allowing a quick dropout result. Enter:
(PW) 57 00 3 *
Mode 4 allows both carrier access and PL operation. Since PL is more
easily detected, PL users will find increased range. Carrier access users are
unaffected. The squelch may be tightened to suppress band-opening
problems. ANTI-PL is used when the repeater is co-channel with another,
PL-accessed repeater. Users of the second system are kept out of the
ANTI-PL system. If you rebroadcast Westlink, the NO ACCESS mode
means that transmissions on the repeater input are ignored and can't
interfere with the broadcast. If you need to control the system on its input,
place the DTMF decoder in a PL mode.
