CHAPTER 3: Installation
On MX320 models, the DB25 connector is
proprietarily pinned as a V.35 DTE. A DB25 male to
M/34 female patch cable is included with the unit;
attach this to channel 1 to give the X.25 PAD-2 a
standard V.35 DTE port. To attach this to a V.35 DCE
(CSU/DSU, etc.) with an M/34 female connector, use
straight-through-pinned shielded V.35 cable such as
product code EYN450-MM. To connect to other types of
V.35 devices/ports, call Black Box Technical Support.

Channels 2 and 3 are the X.25 PAD-2’s async local
channels. Their RJ-45 female connectors are
proprietarily pinned as RS-232 DCE.
The PAD-2 comes with a single RJ-45 male to DB25
female patch cable that you can use to attach one of
these channels to the DB25 male serial port of a PC or
terminal for easy configuration. After you configure the
PAD-2, you can leave this cable on if this PC or terminal
will be communicating across the packet-switched link;
this cable can support data transmission as well. Call
Black Box Tech Support if you’d like a second such
cable, or if you need an adapter for this cable to attach a
DB25 female DCE at this distance.
