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, remov e 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.

14. DNF Controls Limited Warranty
DNF Controls warrants its product to be free from defects in material and
workmanship for a period of one (1) year from the date of sale to the original
purchaser from DNF Controls.
In order to enforce the rights under this warranty, the customer must first contact
DNFs Customer Support Department to afford the opportunity of identifying and
fixing the problem without sending the unit in for repair. If DNF’s Customer Support
Department cannot fix the problem, the customer will be issued a Returned
Merchandise Authorization number (RMA). The customer will then sh ip the defective
product prepaid to DNF Controls with the RMA number clearly indicated on the
customer’s shipping document. The merchandise is to be shipped to:
DNF Controls
12843 Foothill Blvd., Suite C
Sylmar, CA 91342
USA
Failure to obtain a proper RMA number prior to retu rning the product may result in
the return not being accepted, or in a charge for the required repair.
DNF Controls, at its option, will repair or replace the defectiv e unit. DNF Controls will
return the unit prepaid to the customer. The method of shipment is at the discretion
of DNF Controls, principally UPS Ground for shipments within the United States of
America. Shipments to international customers will be sent via air. Should a
customer require the product to be returned in a more expeditious manner, the
return shipment will be billed to their freight account.
This warranty will be considered null and void if accident, misuse, abuse, improper
line voltage, fire, water, lightning or other acts of God damaged the product. All
repair parts are to be supplied by DNF Controls, either directly or through its
authorized dealer network. Similarly, any repair work not performed by either DNF
Controls or its authorized dealer may void the warranty.
After the warranty period has expired, DNF Controls offers repair services.
Equipment is evaluated and repair price quoted prior to any work performed. DNF
Controls reserves the right to refuse repair of any unit outside the warranty period
that is deemed non-repairable.
DNF Controls shall not be liable for direct, indirect, in cidental, consequential or oth er
types of damage resulting from the use of the product.
