Network Connections - Biamp Vocia GPIO-1 Manual Del Operador

Network Connections

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 100Base-T Ethernet switch (not repeater hub) is required when networking multiple units. CobraNet
utilizes standard CAT5, CAT5e, CAT6, or CAT7 cabling, which has a specified maximum length of 328
feet (100 meters. Additional Ethernet switches, or switches which provide fiber-optic interface, can be
used to extend the physical distance between units within a network. Please note that CobraNet limits
network extensions to seven hops (one-way transmissions) within a network. The CobraNet network
connection is configured with the primary connector on the left and the secondary (redundant) connector
on the right. The primary and secondary CobraNet ports are provided to facilitate connection redundancy.
Each connector provides two LEDs that indicate Ethernet link and network activity.
Each RJ45 connector uses two LEDs to indicate Ethernet link and network activity (see table below).

None Flashing green Link established. Typically seen on the Secondary port when acting as a failover to the Primary connection
Device ID switches
The rotary ID switches give the unit a unique Device ID. The switches are in hexadecimal format. All units
of the same device type must have a unique Device ID to function properly within a Vocia Paging World.
The Factory Default Device ID is 01. A Device ID of 00 is invalid and cannot be used.
To assign a Device ID of hex 07, leave the MSB switch on 0 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) flat blade screwdriver.
Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.
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 configured 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 configured 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 eachinput for short to ground and open circuit. In order to sense open
