EDMAC Slave
Address Range
(Modem only)
ESA= 4 bytes Command or Query
EDMAC Slave Address Range – sets the range of
addresses of distant-end units (modems or transceivers),
which this unit, as the Master, will forward, messages for.
Only values which are integer multiples of 10 are
permitted (0010, 0020, 0030, 0040, etc)
Example: ESA=0090
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.
