Arguments for Description of arguments
Command or (note that all arguments are ASCII numeric codes, that is,
Response to ASCII codes between 48 and 57)
Query
4 bytes, Command or Query.
numerical 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 define the unit as being an EDMAC
Master.
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.
24 bytes, Command or Query.
ASCII Sets or queries the user-defined Circuit ID string, which is a
fixed length of 24 characters.
Valid characters include:
Space ( ) * + - , . / 0-9 and A-Z.
1 byte, value of Command or Query.
0 or 1 Enables or disables communication, via an FSK serial link,
with a Comtech Transceiver (Outdoor unit).
0 = disabled
1 = enabled
Example: ODU=0
1 byte, value of Command or Query.
0 or 1 Enables or disables AUPC (Automatic Uplink Power Control).
0 = disabled 1 = enabled
Example: AUP=0
Note: Framing must be selected for the AUPC feature to work.
If AUPC is selected when Framing is disabled, AUP* will be
returned
