Front Panel Layout - GasTech GTA-4100R Operator's Manual

1.2 Front Panel Layout

The diagram below shows the layout of the front panel. Each GTA-4100R card is divided into two identical
channels - top and bottom. Each side of the card is completely isolated from the other and operates
completely independently. The only shared component is the LCD and the card will continue to work correctly
even if the LCD fails. This is a non critical device and is written to by both processors but has no affect on either
channel.
