Remote Control Operation
Where:
x = 3 or 4 (channel number).
yyy = NRM (normal data phasing) or INV (inverted
data phasing).
Where: xxxx = OFF (Disabled), DI (D&I Enabled), T1E1
(T1/E1 Enabled).
Note: This command enables channel #1 for D&I
operation, T1/E1 operation, or can be disabled.
Where: xxxx.x = 1544.0 or 2048.0 kbit/s for T1/E1
operation. N * 64.0 kbit/s for D&I operation.
Where: xxx = OFF (ADPCM Disabled), ON (ADPCM
Enabled).
This command enables channel #2 for ADPCM operation,
or can be disabled.
Where: xxxx = OFF (Channel Disabled), AUPC (Channel
Enabled for AUPC), A232 (Channel Enabled for ASYNC
RS232), S232 (Channel Enabled for SYNC RS232), A422
(Channel Enabled for ASYNC RS422), S422 (Channel
Enabled for SYNC RS422).
Note: This command enables channel #3 for
SYNC/ASYNC RS232/RS422 operation, AUPC
operation, or can be disabled.
Where: xxxx.x = 0.6 to 4000.0 for Sync. RS422 (kbit/s in
100 bit/s steps). 0.6 to 64.0 for all other modes (kbit/s in
100 bit/s steps).
Where: xxxx = OFF (Channel Disabled), AUPC (Channel
Enabled for AUPC), A232 (Channel Enabled for ASYNC
RS232), S232 (Channel Enabled for SYNC RS232), A485
(Channel Enabled for ASYNC RS485).
Note: This command enables channel #4 for
SYNC/ASYNC RS232 operation, ASYNC RS485
operation, AUPC operation, or can be disabled.
Where: xx.x = 0.6 to 64.0 (kbit/s in 100 bit/s steps).
Where:
x = 3 or 4 (channel number).
yyy = NRM (normal clock phasing), INV (inverted
clock phasing).
