If you want to dial up to ports on the IPE Module or the Application
Module, you can use any one of five modems: Universal Data Systems
(UDS) 2440 A/D modem, EC224 A/D modem, Ven-Tel 2400 baud modem,
Ven-Tel 2400 Plus II baud modem, and Ven-Tel 9600 plus baud modem.
The following pages show the locations and settings of the switches on
these modems.
It is important to note that regardless of which modem you select, the
identical model of modem must exist at both ends for dial-up capability to
work properly. For example, if the remote terminal or printer has a UDS
EC224 A/D modem, the modem at the IPE Module or Application Module
site must also be a UDS EC224 A/D modem.
All of these modems (at the Application Module site) are connected to a
VME multi-port cable. Attach one VME multi-port receptacle, or (at the
IPE Module site) the appropriate port on the NT1R03AA or NT1R03BA
cable, to a null-modem adapter, then connect the adapter to the DB25 socket
on the modem. At the device end, connect the terminal or printer to the
modem using a straight DB25 cable.
