Query
Command or Query.
Sets or returns fine adjustment of the modem Internal 10MHz Reference in the
form sddd, where:
s = sign (+ or –), and
ddd = value from 000 to 999
Command or Query.
Sets or returns Warm-up Delay for internal frequency reference (OCXO) in the form
x, where:
0 = Disabled (instant on – no delay for OCXO to reach temperature)
1 = Enabled (unit waits until OCXO reaches correct temperature)
Example: <0/WUD=1 (selects Warm-up Delay)
Command or Query.
As a command, only takes the argument 000. Truncates the Warm-up delay
period to zero and forces the unit into 'instant-on' mode. For example, CTD=000
terminates the warm-up delay.
As a query, returns the Warm-up Delay countdown, in seconds remaining. Range
is from 000 to 200 seconds.
For example: <0/CTD?
>0/CTD=067 (means the unit will wait another 67 seconds before it
enters its operational state)
Command or Query.
Sets or returns the CDM/R-570AL Test Mode, where:
0 = Normal Mode (no test)
1 = IF Loopback
2 = Digital Loopback
3 = I/O Loopback
4 = RF Loopback
5 = Tx CW
6 = Tx Alternating 1,0 Pattern
Example: <0/TST=1 (IF Loopback)
Query only.
Returns the number, in the form xxx, of stored events which remain unread over
the remote interface.
Example: <0/NUE?
>0/NUE=126
