A9245-E-001 User Guide

4.3 GPIO Cable

The GPIO cable contains four sets of GPIO Outputs. Each set of GPIO output consists

of two terminals. A9245-E-001’s GPIO outputs do not actually provide output signals.

Instead, it routes user’s I/O signal connected to output port’s No.1 terminal to the No. 2

terminal upon receiving appropriate GPIO command from A9245-E-001’s RS-232 or

RS-485 interface as shown in the diagram below. User of A9245-E-001 needs to

provide adequate signal at terminal No.1 for his own purpose.

GPIO Cable

Output Terminal Characteristics:

Voltage Range: 3~ 24V with respect to ground

Current Handling: 2A max

Toggle Threshold: +5VDC with respect to ground

GPIO Output Connection

Attach one of the cables with 10-pin circular connector at one end to the GPIO

receptacle. Make sure the “key tab” on the connector matches before inserting the

connector to the receptacle. Tighten the connector by turning the circular collar. The

flying leads on the other end of the cable are for user to hook up to his GPIO device.

Please see table-1.0 for wire signal definition. Please make sure that the ground signal

is also connected to the GPIO device to ensure proper system operation.
