CANADIAN DEPARTMENT OF COMMUNICATIONS
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and
if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A
computing device in accordance with the specifications in Subpart J of Part 15
of FCC rules, which are designed to provide reasonable protection against
such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to
cause interference, in which case the user at his own expense will be required
to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of the Canadian
Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par le ministère des Communications du Canada.

DUAL PORT RS-232 SERIAL INTERFACE
2.1 Overview
The Dual Port RS-232 Serial Interface provides your PC system with two RS232 asynchronous ports. Connect to any device that uses the RS-232 protocol,
such as modems, data-entry terminals, and plotters.
The Serial Interface also includes a serial utility diskette with Seacom, a DOS
interrupt and driver package. Seacom allows data to be buffered, eliminating
data loss in high-speed data transfers. It also allows more than 4 ports (256
max.) to be configured and utilized under DOS.
The README file on the serial utility diskette contains information about the
latest changes and revisions. To view this file, insert the diskette into drive A
or B and type A:TYPE READ.ME|MORE [ENTER] or B:TYPE
READ.ME|MORE [ENTER].
2.2 What’s Included
Your Serial Interface should come with the following items. If any of these
items are missing or damaged, contact your supplier.
(1) Dual Port RS-232 Serial Interface,
(2) serial utility software diskettes: (1) for 32-bit Windows®,
(1) for DOS and Windows®3.1x

CHAPTER 2: Introduction
2.3 Features
Listed below are the special features your Serial Interface offers.
• Each port is independently addressable.
• Eight interrupt options, including AT interrupts, for simple integration
into existing systems.
• IRQs can be shared or individually set for each port.
• Supports Interrupt Sharing—only one interrupt line required for multiple
ports.
• Supports any character set defined by binary notation.
• 16550 UARTs (IC110C) or 16950 UARTs (IC174C) help ensure against
data loss.
• Faster baud rates—up to 115.2 Kbps (IC110C) or 460.8 kbps and higher
(IC174C).
• Dual DB9 male AT®style connectors.
• Individually selectable address and interrupt (2–5 and 10, 11, 12, or 15 on
the AT connector) for each port.
