RADIO FREQUENCY INTERFERENCE STATEMENT

Class B Digital Device.

This equipment has been tested and found to comply with

the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful

interference in a residential installation. However, there is no guarantee that

interference will not occur in a particular installation. This equipment generates,

uses, and can radiate radio frequency energy, and, if not installed and used in

accordance with the instructions, may cause harmful interference to radio

communications. If this equipment does cause harmful interference to radio or

telephone reception, which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference by one of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

• Consult an experienced radio/TV technician for help.

Caution:

Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to operate the

equipment.

To meet FCC requirements, shielded cables and power cords are required to

connect this device to a personal computer or other Class B certified device.

This digital apparatus does not exceed the Class B 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 classe B prescrites dans le Règlement sur le brouillage

radioélectrique publié par le ministère des Communications du Canada.

salen del aparato.

14. El equipo eléctrico debe ser limpiado únicamente de acuerdo a las

recomendaciones del fabricante.

15. En caso de existir, una antena externa deberá ser localizada lejos de las

lineas de energia.

16. El cable de corriente deberá ser desconectado del cuando el equipo no

sea usado por un largo periodo de tiempo.

17. Cuidado debe ser tomado de tal manera que objectos liquidos no sean

derramados sobre la cubierta u orificios de ventilación.

18. Servicio por personal calificado deberá ser provisto cuando:

A: El cable de poder o el contacto ha sido dañado; u

B: Objectos han caído o líquido ha sido derramado dentro del

aparato; o

C: El aparato ha sido expuesto a la lluvia; o

D: El aparato parece no operar normalmente o muestra un cambio en

su desempeño; o

E: El aparato ha sido tirado o su cubierta ha sido dañada.

1. Specifications

RS-232 HS

2.1 Overview

The RS-232 HS provides the PC with 2 asynchronous serial ports. It also

provides a jumper to select clocking modes that allow much higher data

rates than those typically associated with RS-232. With its high-speed

drivers and receivers, the RS-232 HS can handle rates up to 460 Kbps. The

RS-232 HS can be configured as COM1: through COM4:, providing a

versatile interface for common RS-232 needs (such as a modem, mouse, or

plotter) as well as higher-speed applications (like ISDN, V.34 modems, etc.).

The IC130C uses the 16650 UART chip, which features programmable

baud rate, data format, interrupt control, and a 32-byte input and output

FIFO. The IC177C uses the 16950 UART, which features a 128-byte FIFO.

In addition, the RS-232 HS supports IRQs 2–5, 7, 10, 11, 12, and 15. And

shareable IRQs allow more than one port to share a single IRQ.
