Alphanumeric Messaging

152 025-9034AA

When the device is equipped with a modem, 300-baud modems should be Bell 103 compatible;

1200-baud modems should be Bell 212 compatible.

The Dual Trunk is capable of either 300 or 1200 baud dialup. For general compatibility with the

outside world, 300 baud should be used. This is the default we set unless you tell us otherwise.

The test page facility is not used for normal paging. It is not used by way of the MultiPort or Dual

Trunk cards. It is used by way of the ZlinkW function in ZbaseW, into the maintenance port (local or

remote). Its purpose is for testing only.

Communication Parameters

Serial communications may be done by way of modem, normally using the Bell 103J

standard, or by way of direct serial connection. Standard parameters are:

300 baud

7 data bits

1 parity bit, even parity

2 stop bits (1 stop bit OK)

Full duplex

No echo

If you are using a standard terminal such as an Alphamate or iXo, they are already set up

this way standard from the factory. If necessary, these parameters can be modified for non-

standard uses; see System Configuration Files in Series 2000 Paging Terminals

Installation and Maintenance.

Video Display Terminals

A video display terminal (VDT) is most useful for receptionists, operators, or dispatchers

who require constant access to the paging system for sending messages. The alpha

messaging option can handle display messages for alpha and numeric-only pagers. VDTs

are normally connected to a port on the Multiport Serial card (702-9191), although it is

also possible to use a modem and a Dual Trunk card (702-9117) with the Dual

Alphanumeric Messaging input modem option (950-9108). The descriptions given below

are for the Multiport Serial card, with differences noted for the Dual Trunk card where

appropriate.

Note If communicating by way of modem, it is very important that line

levels and balance be properly adjusted; refer to the Installation

manual for adjustments.
