INSTALLATION
Inspection
Please examine your GPI-16 + G2 NET carefully for any damage that may have
been sustained during shipping. If any is noted, please notify the shipper immedi-
ately and retain the packaging for inspection by the shipper. The package contains
the GPI-16 + G2 NET, a USB type A/B cable, a 7-foot BLUE straight-through CAT
5 cable, a 7-foot GRAY crossover CAT 5 cable, and a 9.0 VDC universal desktop
power supply with IEC AC inlet. Manuals may be downloaded from our web site.
Installation
Power
Connect the 2.1mm barrel type center positive power connector into the unit and the
9 VDC power supply with IEC inlet into a 120 Vac 50-60 Hz power source.
NOTE: Never use any type of power supply other than the specified/supplied power
supply. Check the power jack on the back of the unit to determine which power sup-
ply is required.
UPS Standby Power System
We recommend that you connect your GPI-16 + G2 NET to a UPS standby power
system. A UPS, like the BE600M1 from APC helps to minimize the risk to the GPI-
16 + G2 NET and provides power during a power outage.
Input connections
The sixteen 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 a single 18-position plug-in euroblock screw terminal that
is labeled “Inputs” 1 thru 16 with ground connections on terminals 17 and 18. To
install, remove the plug from the header, strip 1/8” of insulation from the wire.
Insert the wire into the desired terminal and tighten the set screw. When finished,
reinsert the plug into the header.
USB Port
This type B USB port is used to connect the GPI-16 + G2 NET to a computer’s USB
port using the included USB A/B cable. When you first plug the GPI-16 + G2 NET
into your PC, it should automatically install the correct FTDI USB Serial “Virtual
COM port” driver which will allow you to access the GPI-16 + G2 NET on a COM
port. If the GPI is being used for Ethernet operation this should remain disconnected,
and the drivers are not necessary.
NOTE: If the GPI-16 + G2 NET’s FTDI USB Serial “Virtual COM port” drivers do
not automatically install they may be downloaded by clicking on the “setup exe-
cutable” link found here: http://www.ftdichip.com/Drivers/VCP.htm
CAUTION!
Installation of the GPI-
16 + G2 NET in high
RF environments
should be performed
with care. It is recom-
mended that all cables
connected to the GPI-
16 + G2 NET be
looped through ferrite
cores to suppress RF.
Surge protection with
RF filtering is also sug-
gested for the power
supply. For lightning
protection devices,
check out

OPERATION
AT1616 Information Retrieval Commands
In AT1616 format mode the GPI-16 + G2 NET sends a response string in AT1616
format each time an input changes state. In AT1616 format mode the unit ID is set-
ting is ignored and the baud rate is fixed at 9600.
Each string consists of a dash (-) followed by 8 bytes. The first 4 bytes are ASCII
hex representations of the 16 outputs which are not included in the GPI-16 + G2
NET, but are issued as all zeros.
The last four bytes represent the 16 inputs in ASCII hex format with four bytes:
16,15,14,13 12,11,10,9 8,7,6,5 4,3,2,1. If inputs 1,4,7,8,9,10,14,16 are all ON
(pulled to ground), then these four bytes would appear as: A3C9. In the above
example, the complete string would be -0000A3C9
Additional response examples:
Response string example for input 1 pulled low: -00000001
Response string example for input 1 returning high: -00000000
Response string example for input 2 pulled low: -00000002
