CDM-550T Satellite Modem
Rev. 1.3
(CONFIG, FRAME, FRAMED) EDMAC-ON
SELECT EDMAC MODE:
MASTER
SLAVE
Select either MASTER or SLAVE, using the LEFT/RIGHT 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 which is not local to the M&C computer, which is
at the distant-end of a satellite link. If MASTER is selected then the following
sub-menu is displayed:
(CONFIG, FRAME, FRAMED, ON) EDMAC MASTER
EDIT DISTANT-END'S ADDR:
0240 (SEE HANDBOOK)(ENT)
Edit the address of the distant-end modem which this unit will pass messages to.
This is accomplished by selecting the digit to be edited, using the LEFT/RIGHT
arrow keys. The value of the digit is then changed using the UP/DOWN arrow
keys. The user should then press ENTER.
There is a restriction on values which 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. The valid range of
addresses is from 10 to 9990.
But if SLAVE is selected, then the following sub-menu is displayed:
(ENTER)
