VOCIA GENERAL PURPOSE INPUT OUTPUT DEVICE (GPIO-1)
The GPIO-1 provides sixteen general purpose inputs and sixteen general purpose outputs to control various aspects of a Vocia system.
The GPIO-1 is a monitored device and can be used in life safety applications where more logic inputs or outputs are required. The GPIO-1
has dual powering from PoE Ethernet ports and alternate powering from dual 24V DC inputs. In the event of power loss changeover
between power sources will provide uninterrupted operation.
FEATURES
• Sixteen general purpose logic input and outputs
• Device monitoring
• Able to be used to directly interface with re alarm and emergency equipment
• PoE capable with alternate powering from auxiliary 24V DC supply (dual inputs)
• Software-congurable
• Control over a single Ethernet cable
• Dual Ethernet ports for redundancy
• Rotary switches for device identication
• IP30 Compliant
• CE marked, UL listed and RoHS compliant
• Covered by Biamp Systems’ ve year warranty

GPIO-1 SETUP AND USE
Setup and Use
The Vocia software provides the interface for conguring and programming the GPIO-1. The information supplied by this manual relates
to hardware installation, physical connections and device information. For more details on the software setup please consult the Vocia
Software Help File.
Network
The GPIO-1 is designed to be used in a single Vocia World and utilizes the Vocia CobraNet LAN to communicate.
The unit has two monitored RJ45 Ethernet Network connectors to facilitate redundant connections. The Primary connection will always have
priority over the Secondary connection. Monitoring of the secondary connection can be disabled in the software.
A green power LED is provided and illuminates when PoE power is applied to the unit via either Network port.
Each RJ45 connector uses two LEDs to indicate Ethernet link and network activity (see table below).
Left LED Right LED Description
None None No data connectivity
Yellow Flashing green Network link established. Port is in use
None Flashing green Network Link established. Typically seen on the Secondary port when acting as a failover to the
Primary connection
The maximum distance between any unit and an Ethernet switch is 100 meters (328 feet) when using copper cabling. Additional
Ethernet switches and/or ber-optic cable can be used to further extend distances between devices on a network.
Device ID
The rotary ID switches are located on the GPIO-1 and give the unit a unique Device ID. The switches
are in hexadecimal format. All GPIO-1 units must have a unique Device ID to function within a Vocia
Paging World (i.e., it is not possible to have two GPIO-1 units with the same Device ID of hex 07). To
assign a Device ID of hex 07, turn the MSB switch to 0 and turn the LSB switch to 7. To create an ID
of hex B7, turn the MSB switch to B and turn the LSB switch to 7. Device ID switches should be set
using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) at blade screwdriver. More information on setting IDs and the hexadecimal numbering
scheme used in Vocia can be found in the Vocia Help File.
Please note: Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.

GPIO-1 SETUP AND USE
Input Connectors
Sixteen parallel input connections are provided on the GPIO-1 as well as Isolated Ground and Ground connections. Under software control
the logic level of each input can be set independently to operate one of three ways.
• TTL: 2V to 5V logic sense. To enable a TTL input, apply a TTL logic high or low with respect to Isolated Ground. This can be
congured in software to detect a low to high or high to low transition.
• High Range: To enable a High Range input, use a dry contact to switch the input to a voltage of 24V DC with respect to Isolated
Ground. This can be congured in software to detect a low to high or high to low transition.
• High Range – Monitored: This circuit is implemented in the same way as the High Range input. This option allows monitoring of each
input for short to ground and open circuit. In order to sense open circuit, a terminating resistor must be tted between each Input and
Isolated Ground at the far end of the circuit being sensed. The Inputs will sense open circuits on the line between its input and the
terminating resistor. Shorts to Isolated Ground are sensed across the entire line being monitored. A 6k8Ω resistor should be used for
each input. If a monitoring fault is detected on any input the logic state or transitions on that input will be ignored until the fault is cleared.
High Range – Monitored inputs require a low to high transition to enable the input (transition direction not congurable).

GPIO-1 SETUP AND USE
Output Connectors
Sixteen parallel outputs are provided on the GPIO-1 as well as Isolated and Chassis Ground connections. Each output is able to accept
either an external positive voltage between 4 and 30V or use the 24V DC 100mA reference voltage provided on the unit. The 24V DC
supply for use with the Aux Power port is not provided with the unit and will need to be sourced locally. Outputs will be monitored for short
to ground, short to supply and if High Range - Monitored is being used, open circuit conditions will be monitored as well. Consideration
should be given to the state of the output when network connectivity is lost. A Voltage Monitor (VM) input is provided in order that a short
to supply reference voltage is incorporated in output Fault monitoring. A voltage of between 4 - 30V is required by the VM input in order for
the outputs to operate.
If the GPIO-1 Outputs are using a High Range Monitored type of circuit the VM input must match or be greater than the highest Output
Voltage being used. If a higher Voltage is seen on the Outputs compared to the VM Input a Short to Supply fault will be indicated.

GPIO-1 SETUP AND USE
Power
Caution - Due to potential energy hazard, connections to the Auxiliary Power 24V DC
inputs must be made by a qualied electrician or other qualied person as
required to conform with all local codes.
The GPIO-1 will be capable of operation from two power supply types - PoE and 24V DC. Any or all power sources may be connected
concurrently. Loss or return of any power source will not result in interruption to operation. PoE power has priority over 24V DC when both
sources are connected. Fault monitoring of each Power Supply input is enabled by default. The Vocia software allows monitoring to be
enabled or disabled on each power supply.
If PoE Power is to be used an 802.3af Class 3 or 802.3at Type 1, Class 3, compliant PoE switch or mid-span adapter is required to either
or both Ethernet ports.
When power is present at either or both of the 24V Aux power inputs the adjacent green power LED indicator will illuminate. When PoE
power is present at either or both of the Ethernet ports the adjacent green power LED indicator will illuminate.
