Procedure 14

Connecting two or more LEIs to the MMI terminal

Step

Action

Follow this procedure for connecting two or more LEIs to the MMI terminal:

Cable the DB9 male connector labeled "P5" (toward MMI terminal)
to one of the COM ports on the back of any TTY, a PC running a
terminal emulation program, or a modem.

Make the connection from the first card to the second card by
plugging the DB9 female connector labeled "P4" (away from MMI
terminal) from the first card into the DB9 male connector of the
second card labeled "P5" (toward MMI terminal).

Repeat step 2 for the remaining cards.

At the last card of the daisy chain, make no connection from the DB9
female connector labeled "P4" (away from MMI terminal).

If two LEIs are too far apart to connect the "P4" and "P5" connectors
connect them with an off-the-shelf DB9 female to DB9 male
straight-through extension cable, available at any PC supply store.
