Æ FRAMED) EDMAC-ON
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 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
Æ FRAMEDÆ ON) EDMAC MASTER
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 [
←] [→] arrow
keys. The value of the digit is then changed using the [
↑] [↓] 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:
(CONFIG: FRAME Æ FRAMED Æ ON) EDMAC SLAVE
Edit the address of this SLAVE unit. This is accomplished by selecting the digit
to be edited, using the [
←] [→] arrow keys. The value of the digit is then
changed using the [
↑] [↓] arrow keys. The user should then press ENTER. The
valid range of addresses is from 1 to 9999, although ‘base 10' values will be
automatically skipped.
