Chapter 1: Setting Up Your USB Faxmodem

11

The USB faxmodem has a set of eight indicator lights on

the front. A chart explaining what the lights mean appears

below. This chart is also reproduced in condensed form on

the bottom of the faxmodem.

OH (Off Hook)

Lights when the faxmodem is off hook.

Flashes whenever data or commands are trans-

mitted from the serial port of your computer (or

other device) to the faxmodem, or vice-versa. At

high speeds the light may appear to be continu-

ously on.

Blinks on and off when detecting incoming ring.

Lights when the Data Carrier Detect (DCD) signal

from the faxmodem to the computer is on.

EC/DC (Error Correc-

tion/Data Compression)*

Lights when using V.42 or MNP 4 error correction

and V.42bis or MNP 5 data compression.

Lights when communicating in V.90 or K56flex™

mode.

Lights when a fax connection has been made to

another faxmodem or to a fax machine.

Lights when the faxmodem is turned on; is unlit

when the computer is in power-save mode.

*Error Correction/Data Compression filters out line noise, repeats transmissions auto-
matically if an error occurs, and automatically compresses data

 

when it’s sent and de-

compresses it when it is received.

Consult the Software Installation Guide that came with

your faxmodem to install a complete faxing and communi-

cations package that will help you get the most out of your

modem. Also explore the other software offerings on the

Zoom Link CD. The CD describes each program and offers
