11. 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 GTP-32 Breakout Panel or using jumpers within the GTP-32. To
configure the jumpers inside the GTP-32:
1) Power down the GTP-32.
2) Using a Phillips screwdriver, remove the top cover from the GTP-32. To do
so, you will need to remove 3 screws from each side of the unit, 2 from
the rear, and 1 from the center of the front of the unit.
3) The GPIO card is on the far right hand side of the unit (if facing the front
panel), behind the GPIO connectors.
4) 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.
5) For Dry operation, set one jumper across pins 2 and 3. Hang the second
jumper off of pin 1.
6) For Wet operation, set one jumper across pin 1 and 2. Set the second
jumper across pins 3 and 4.
7) Once all necessary changes to the jumpers have been made, replace the
top cover and screws on the GTP-32.
