Description of Arguments
Response to
Command
Query
(Instruction
& Qualifier)
Response to Query
EDMAC Slave
Address
Range
ESA= 4 bytes Command or Query.
Sets or returns EDMAC range of addresses of distant-end units (modems or transceivers) for which this
unit, as the Master, will forward messages. Only values which are integer multiples of ten are permitted.
(0010, 0020, 0030, 0040 etc.)
EXAMPLE: <0/ESA=0090
NOTE: This command is only valid for an EDMAC master. When used as a Query, it may be sent to an
EDMAC slave, which will respond with the appropriate address.

ESA? ESA=xxxx
(see Description of
Arguments)
One Time
EDMAC Slave
Overwrite
OTO= 1 byte,
0 or 1
Command or Query.
Sets or returns One Time Overwrite to EDMAC Slave modem in the form x, where:
0=Off
1=On
EXAMPLE 1: OTO=0 disables One Time Overwrite – EDMAC Slave modem may only remotely accept
EDMAC command from EDMAC Master modem.
EXAMPLE 2: OTO=1 enables One Time Overwrite – EDMAC Slave modem may locally accept ONE
remote control command.

External
Frequency
Reference
EFR= 1 byte,
0 thru 6
Command or Query.
Sets or returns the External Frequency Reference in the form x, where:
0=Internal 10MHz (DEFAULT)
1=External 1 MHz
2=External 2 MHz
3=External 5 MHz
4=External 10 MHz
5=spare
6=Internal 10MHz plus output (this means that the Reference is available on the “Ext Ref” rear
connector (small rear-panel LED indicates when ON))

for Internal
10MHz High-
stability
Reference
ADJ= 4 bytes,
numeric
Command or Query.
Sets or returns fine adjustment of the Internal 10MHz Reference on the High-Stability Frequency
Reference module in the form sddd, where:
s=sign (+ or –)
ddd=Value, 0-999

Warm-up
Delay
WRM= 1 byte,
0 or 1
Command or Query. (Hi-Stability Frequency Reference parameter)
Sets or returns the High-Stability Frequency Reference warm-up delay parameter in the form x, where:
0=Delay off (instant on)
1=Warm-up Delay on
WRM=

Countdown of
Warm-up
Delay
remaining
CTD= 3 bytes,
numeric
Command or Query. (Hi-Stability Frequency Reference parameter)
Sets or returns the High-Stability Frequency Reference countdown parameter in the form xxx, where:
xxx=countdown of the number of seconds remaining of the Warm-up time.
NOTE: As a command, the only permitted format is CTD=000, which abandons the delay.
