Step Five: Install peripheral cabling
You can connect printers, terminals, modems (or an y other standard EIA-
232 device to be controlled by applications on the computer) to the
EPC/CON-16 concentrator by installing a cable between the peripheral
and the concentrator.
On the peripheral end of the cable, the cable connector depends on the
requirements of the peripheral. The EPC/CON-16 (or PORTS/Xem mod-
ule) end of the cable must fit either an RJ-45 or DB-25 connector,
depending on the model you have.
The pin assignments for each type of EPC/CON-16 connector are as fol-
lows:
DB-25 Pin assignments
RJ-45 pin assignments are shown on the back.
RJ-45 Pin Assignments
Refer to the CD-ROM for more detailed cabling information.
What Next?
At this point the hardware installation for your EPC/X system is com-
plete. However, since the EPC/X adapter and the EPC/CON-16 concen-
trators must have software downloaded to their internal RAM before they
become functional, you must next install the software drivers for your
operating system.
• Read the instruction booklet for the CD-ROM that came with your
system for instructions on installing software.
• View the on-line documentation on the CD-ROM for more informa-
tion about your EPC/X system.

Introduction
An AccelePort® EPC/X™ system consists of an EPC/X host adapter cou-
pled with EPC/CON-16™ concentrators from which EIA-232 peripheral
devices such as printers, terminals or modems can be cabled and con-
trolled. The adapter has two lines that can each support one or more con-
centrators. Multiple concentrators can be linked in a chain, and Digi
PORTS/8em™, PORTS/16em™, Modem/4em™, and/or Modem/8em™
modules can be added to a concentrator to expand the number of ports
available .

This installation guide describes how to plan your setup and install the
EPC/X host adapter and concentrator hardware.
