Mode 0,1,2,3,4 or 5
Unit IF IMP= 1 byte, value of
5 or 7

Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
1 = IF loopback
2 = Digital loopback
3 = I/O loopback
4 = Tx CW
5 = Tx Alternating 1,0 pattern
All other codes invalid. Example TST=4 (which is
transmit CW)
Command or Query.
IF interface impedance, where:
5 = 50 ohms
7 = 75 ohms
All other codes invalid. Example IMP=7 ( 75 ohms)
Command or Query.
Alarm mask conditions, in the form abcde, where:
a = mask Tx AIS alarm, b = mask Rx AGC alarm
c = mask buffer alarms, d = mask Rx AIS alarm
e = mask Eb/No alarm
Setting any of these bytes to 0 unmasks alarm,
setting to 1 masks them. Example: MSK=01011
Command or Query.
EDMAC Slave Address - sets the range of
addresses of distant-end units (modems or
transceivers) which this unit will forward messages
for. Only values which are integer multiples of ten
are permitted. (0010, 0020, 0030, 0040 etc.)
Example: ESA=0890
Important Note: Setting the value of the EDMAC
Slave Address to 0000 disables this function.
Setting a valid address here will automatically
