8 DBRA (Data Bridge Card) Startup and Configuration Guide

There are 2 version of the 8DBRA card, one with 2 RJ45s and 2 HD44 connectors that require 2

fanout cables, each with one DE9 and 2 DB25s. The other card has 8 RJ45 connectors. The all

RJ45 version is preferred because the connectors are all the same. The card supports transmit

data, receive data and ground on each port. RS232 control leads are not supported.

The 8DBRA card with the 8 RJ45 connectors provides easier, cleaner looking connections.

The 8 DBRA card supports asynchronous ports at any speed up to 19,200 bps. The speed

setting in the 8DBRA card setup screen is for reference only.

The 8DBRA card is compatible with other 8DBRA cards and any synchronous RS232 56Kbps or

64 Kbps card or 56K or 64K OCUDP from Loop or other manufacturers (tested!). The 8DBRA

card uses oversampling. See Page 16 for a description of the oversampling technique. Terminal

devices attached to non-8DBRA cards must run at the same speed as the devices attached to

the 8DBRA cards.

The 8 ports of the 8DBRA can be mapped into 3 or 4 Virtual Ports (VP). If the 8DBRA card is

configured for "NO Backup" or "1+1 Port Backup", all 4 of the Virtual Ports are available.

Backing up the entire card in the same or a different chassis limits the card to 3 virtual ports.

Data is carried to the backup card, whether in the same chassis or to a remote site, via one of

the Virtual Ports (VP4).
