Modem to Controller

To make the connection between the master controller and the host computer you will use two cables: one between the
host computer and its modem (see Section 5.2.3 on page 19), and one between the master controller and its modem.

If the modem has a female DB-25 connector, you must use a Keri Systems KDP-336 cable or create a cable as shown
in Figure 18.

If the modem has a female DB-9 connector, you must create a cable as shown in Figure 19.

If the modem was purchased from Keri Systems, it comes with an adapter that accommodates a female DB-9
connector (should the modem have a DB-9 instead of a DB-25 connector). Use this adapter cable in conjunction with
a KDP-336 cable to make the modem/controller connection. See Figure 20 on page 18.

The Keri Systems part number for this cable is KDP-336.
