GPIO-32+2 Installation and Operation Manual

OVERVIEW

Product Overview

The GPIO-32+2 interfaces 32 general purpose logic inputs and the control of two

independent SPDT relays to the user’s PC USB port. The GPIO-32+2 conforms to

the PIP serial format which is used on most of our audio switchers and supported by

most of the radio automation software suppliers. Additional features include; Plug-

in euroblock screw terminals; 36 LED indicators for power, PIP activity, relays K1,

K2 and each of the 32 GPI inputs. By utilizing the 32 GPI inputs and the two relays,

up to 96 GPI's may be monitored. The GPIO-32+2 is supplied with a USB type A/B

cable and 9.0 VDC universal domestic wall power supply. The unit is internally

surge protected. Up to four GPI-32+2’s may be rack mounted on one RA-1, 1-RU

rack shelf.

Features/Benefits

• Two user selectable unit ID's: 0, 1 (polling required.)

• Two user selectable baud rates: 9600, and 38400.

• PIP serial protocol.

• USB interface for connection to PC.

• LED indicators for all 32 inputs, K1, K2, power, PIP/GPI.

• All connections except for the USB type B connector and a coaxial DC jack are

on removable euro-block screw terminal connectors to simplify wiring and serv-

ice, mating plugs are supplied.

• Fully RFI proofed.

• Surge protected internal power supply, universal switching power adapter with

domestic connectors supplied.

• Up to four GPI-32+2’s may be rack mounted on one RA-1, 1-RU rack shelf.

Inspection

Please examine your GPIO-32+2 carefully for any damage that may have been sus-

tained during shipping. If any damage is present, please notify the shipper immedi-

ately and retain the packaging for inspection by the shipper. The package should

contain the GPIO-32+2, a USB type A/B cable and 9.0 VDC universal wall power

supply with domestic connector. Manuals may be downloaded from our web site.

GPIO-32+2 Installation and Operation Manual

INSTALLATION

Installation

Surge Protection

The GPIO-32+2 has built-in resistance to voltage changes; we recommend that you

use a power surge protector or line conditioner on the incoming AC line. Lightning

strikes and/or other high voltage surges may damage your GPIO-32+2 and connect-

ed equipment if it is not properly protected. For lightning protection devices, check

out www.polyphaser.com and www.itwlinx.com.

UPS Standby Power System

We recommend that you connect your GPIO-32+2 to a UPS system. A UPS helps

minimize the risk to the GPIO-32+2 and provides power during a power outage.

Power

2.1mm coaxial DC power jack, 7.5 - 12 VDC, center positive.

USB Port

This type B USB port is used to connect the GPIO-32+2 to a computer

LED indicators

• “PWR” LED: Pulses to indicate normal operation.

• “PIP” LED: Flashes to indicate PIP activity.

• “GPI” LEDs: Indicates individual GPI input activity, 1-32.

• “K1” “K2” LEDs: Indicates K1 and K2 relay state.

Relays

The K1 and K2 SPDT relay connections are via two 3-positions plug-in euroblock

screw terminals. The K1 GD/CM terminal is also a GPI input ground terminal, the

K2 CM terminal can be switched between ground and floating via DIP-switch and

is set to ground from the factory.

GPIO-32+2 Installation and Operation Manual

INSTALLATION

GPI Inputs

The 32 general purpose inputs may be activated by either pulling the input to ground

or releasing the input to a high state. A valid input must be 15ms in duration or

greater. External sources can be contact closures, open collectors or 5 to 24 volt

logic level sources. The impedance of each input is 22K ohms.

Input connections are via two 16-position plug-in euroblock screw terminals labeled

“GPI Inputs” 1 thru 32. The K1 GD/CM terminal is the a GPI input ground termi-

nal, the K2 CM terminal can also be switched between ground and floating via DIP-

switch and is set to ground from the factory. See the “Configuration DIP-switch

Setup” section of this manual for more information.

To install, remove the plug from the header, strip 1/8” of insulation from the wire.

Insert the wire in to the desired terminal and tighten the set screw. When finished,

reinsert the plug into the header.

Up to 96 GPIs may be monitored by using the GPIO-32+2’s to SPDT relays control

the GPI ground connection to the devices being monitored. See the appendix for an

Application Example diagram.

NOTE: All connections and indicators are noted on the top cover label.

Configuration DIP-switch Setup

The configuration DIP-switch package (SW1) is located on GPIO-32+2’s printed

circuit board.

SW1-1 Unit ID

OFF = 0 NON-Polling (default)

ON = 1 Polling is required

SW1-2 Baud rate

OFF = 9600 (default)

ON = 38400

SW1-3 Invert status send and poll bits

OFF = Commands *uSPii & *uSPA data is displayed as normal (default)

ON = Commands *uSPii & *uSPA data sense is inverted in all cases

SW1-4 Unused

SW1-5 K2 common floating/ground

GPIO-32+2 Installation and Operation Manual

INSTALLATION

USB Serial Operation

To control the GPIO-32+2, you must connect it to the USB port of a PC running a

serial terminal program such as HyperTerminal, or PuTTY. When you first plug the

GPIO-32+2 into your PC it should automatically install the correct FTDI USB Serial

“Virtual COM port” drivers which will allow you to access the GPIO-32+2 on a

COM port. Set the terminal program to 9600,8,N,1, flow control to NONE.

Character Echo should also be turned ON.

NOTE: If the GPIO-32+2’s FTDI USB Serial “Virtual COM port” drivers do

not automatically install they may be downloaded here:
