Diagnostics and Loopback Plugs

To verify that the ClassicBoard EIA-232 adapter and ports are functional, 
use the appropriate DB-25 or RJ-45 loopback plug with the ClassicBoard 
EIA-232 PCI diagnostic program. Loopback plugs are typically shipped 
with the product. The PCI diagnostic program and instructions can be 
found on the diagnostic diskette included with the adapter.

What Next?

After installing the hardware, you must install the software driver for 
your operating system. Refer to the appropriate ClassicBoard PCI driver 
installation instructions that came with your adapter.

This device has been tested and found to comply with the limits for Class B digital devices pursuant to Part 15 Subpart 
B, of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a resi-
dential environment. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and 
used in accordance with the instruction manual, may cause harmful interference to radio communications. However, 
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful 
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is 
encouraged to try and correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and the receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Labeling Requirements (FCC 15.19)

This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device

Hardware Installation

and Cable Guide

Introduction

The ClassicBoard PCI adapters easily expand the number of EIA-232 or 
EIA-422 ports available on a computer, allowing you to directly add 
additional peripheral devices such as point-of-sale peripherals, terminals 
or serial printers. 

Resources

The hardware resources for the ClassicBoard PCI adapter are dynami-
cally assigned by the operating system each time the system boots.

Installing the ClassicBoard Adapter

Before Installing the Adapter

Be sure that you have the correct cables for the interface used with 
the ClassicBoard.

Record the adapter serial number (located under the part number 
label). This will enable Digi to provide you with better service, 
should the need arise. 

Unplug power from the computer. 

Put a ground strap on to ground yourself. If one is not available, 
ground yourself by touching an unpainted metal surface, such as the 
computer chassis.

Installation Procedure
1.

Remove the computer cover.

2.

Locate an available PCI slot in your computer and remove the slot 
plate.

3.

Insert the board into the slot and screw the endplate to the computer 
chassis. The endplate must be screwed into the computer chassis to 
remain in compliance with Part 15 of FCC rules.

4.

Replace the computer cover.

5.

Connect the 78-pin connector assembly to the adapter.
