CONFIGURE GPIS FOR DRY/WET OPERATION
GPIs are set to Dry operation by default. The GPIs may be set for Wet mode
using either a Breakout Panel or using jumpers within the GC-32. To configure
the jumpers inside the GC-32:
1. Power down the GC-32 and then remove the top cover.
2. The jumpers for the GPIs are directly behind the GPI connectors, labeled
J7 through J38. Each set of jumpers for a GPI consists of 4 pins. See the
table below for which GPI corresponds to which jumpers.
3. For Dry operation, set one jumper across pins 2 and 3. Hang the second
jumper off of pin 1.
4. For Wet operation, set one jumper across pin 1 and 2. Set the second
jumper across pins 3 and 4.
5. Once all necessary changes to the jumpers have been made, replace the
top cover and power up the GC-32.
