Arguments for
Command or
Response to
Query
Command or Query.
Sets or returns the date in the form ddmmyy, where
dd = day of the month (01 to 31),
mm = month (01 to 12)
yy = year (00 to 99)
Example: <0/DAY=240457 (April 24, 2057)
Command or Query.
Sets or returns the time, from midnight, in the form hhmmss, where:
hh = hours (00 to 23)
mm = minutes (00 to 59)
ss = seconds (00 to 59)
Example: <0/TIM=231259 (23 hours:12 minutes:59 seconds)
Command or Query.
Sets or returns EDMAC mode in the form x, where:
0 = EDMAC OFF (Framing is on, AUPC active)
1 = EDMAC MASTER
2 = EDMAC SLAVE (Query Only)
Example: <0/EFM=1 (EDMAC Enabled as Master)
Command or Query.
Valid only for an EDMAC Master.
Sets or returns EDMAC Slave Address Range, where:
As a command, sets the range of addresses of distant-end units (modems or
transceivers) for which this unit, as the Master, forwards messages.
Example: <0/ESA=0090
As a query, it may be sent to an EDMAC slave, which responds with the
appropriate address.
Note: Only values that are integer multiples of ten are permitted. (0010, 0020,
0030, 0040, etc.).
Command or Query.
Sets or returns External Reference Frequency in the form x, where:
0 = Internal
1 = External 1 MHz
2 = External 2 MHz
3 = External 5 MHz
4 = External 10 MHz
5 = Internal 10MHz plus output (the Reference is available on the "Ext Ref" rear
connector (small rear-panel LED indicates when ON))
Example: <0/ERF=0 (External reference not used – uses internal)
