(Instruction &
Qualifier)
Response to Query
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.

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))

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.
