Maxxsonics MAXX-2400HD manual BNC Connectors, GPIO Connectors, GPI Connector Pinout

BNC Connectors

The following note applies to all video and Genlock connectors:

•A BNC connector used as an output has a 75-ohm source impedance.

•A BNC connector used as an input has a 75-ohm termination.

GPIO Connectors

General purpose control inputs (GPI) may be applied to the GPIO connectors, which are DB-25 pin connectors. These inputs are optically isolated from the server circuitry; individual floating returns are provided. +5 volts may be sourced from pins 18 or 26, or provided from an external source. Current limiting devices are provided within the server.

General purpose status outputs also appear on the GPIO connectors. Open-collector outputs are provided as status outputs, and may be used to drive an external LED or control input.

Refer to the connector pin-out table and partial schematic, following. Inputs and outputs 1-6 are on connector 1, 7-12 are on connector 2, shown in parentheses. The schematic applies to both connectors as well.
