† DSR (Pin 2 on a 10 pin connector, Pin 1 on an 8 pin
connector) can be swapped with DCD by using the ALTPIN
configuration option. ALTPIN reverses the position of these two
signals in 10 pin connectors and allows DCD to be used instead
of DSR on an 8 pin connector.
Consult the driver documentation for how to do this in your
specific operating system.
Refer to the Access Resource CD for more detailed cabling information.

Introduction
™
A Digi Neo adapter easily expands the number of EIA-232 ports avail-
able on your computer, allowing you to cable additional peripheral
devices, such as modems, terminals or serial printers, directly to your
computer.
Digi Neo adapters are equipped with an HD-68 connector to which a spe-
cial Digi connector assembly is attached to provide the peripheral port
connections. There are seven different connector assembly options avail-
able to use with Digi Neo 4 and Neo 8 adapters:
• RJ-45 Connector Box
• DB-25 Connector Box (male connectors)
• DB-9 Connector Box (male connectors)
• DB-25 Fan-out Cable (male or female connectors)
• DB-9 Fan-out Cable (male or female connectors)
This installation guide describes how to plan your setup and install a Digi
Neo adapter.
