CDM-Qx Satellite Modem Revision 6
Front Panel Operation MN/CDMQx.IOM
Selecting
either
of these modes displays the following submenu:
Select either
AUPC-Only
(default) or
AUPC+EDMAC,
using the
◄ ►
arrow keys,
then press
ENTER
.
Note that if framing is enabled (either
EDMAC
or
EDMAC-2
), then
AUPC
is
automatically enabled, but the specific EDMAC feature (passing M&C data from a local
to a distant-end unit) needs to enabled here.
If
AUPC-Only
is selected then none of the EDMAC features are available, even though
framing will still be enabled.
If
AUPC+EDMAC
is selected, the user is further prompted to select whether the unit is
an EDMAC master, or an EDMAC slave:

Select either
MASTER
or
SLAVE
, using the
◄ ►
arrow keys, then press
ENTER
.
An EDMAC
MASTER
is a unit which is local to the M&C computer, and which passes
messages, via the overhead, to a distant-end modem. An EDMAC
SLAVE
is a unit that is
not local to the M&C computer, which is at the distant-end of a satellite link.
Selecting
MASTER
displays the following submenu:
The valid range of addresses is from 10 to 9990. Edit the address of the distant-end
modem to which this unit will pass messages to by selecting the digit to be edited, using
the
◄ ► arrow keys. The value of the digit is then changed using the
#$
arrow keys,
then pressing
ENTER
.
Note:
There is a restriction on values that can be entered here – they may only be in
increments of 10. This is automatically taken care of; the user may not edit the last digit
of the address. This has been implemented so that a single MASTER may pass messages
for up to 10 devices at the distant end.
Selecting
SLAVE
displays the following submenu:
