8.4 Exchanging a Function Board
To exchange a Function Board for an identical board model whilst retaining all previous func-
tions requires the following steps:

Switch the equipment off

Remove all connections to the Function Board to be exchanged

Unscrew the Function Board and pull it out of the System

Transfer all DIP and jumper settings from the old Function Board to the new board

Insert the new Function Board into the System and tighten the screws

Remake all connections

Switch the equipment back on

Set Function Board to the desired configuration via the System 6844(RC) menu if
necessary
Software settings must always be set after replacing a function board by
using the menu in order that the new function board takes over the parame-
ters. Otherwise the parameters of the old board will be displayed but the
new board doesn't take over the new one.
