The Physical Connector

A single 9-pin D-sub connector provides the physical connection for the RS- 232 serial interface of the AXIS 2120. This interface is for use with an external modem and is suitable for speeds of up to 115kbps.

A diagram of the RS-232 connector complete with pinout information is shown below.

The IO Connector

A 4-pole connector is provided for auxiliary IO connections to the AXIS 2120.

Physical Connector

The IO connector provides the interface to a single digital output and a single digital input. A diagram for the connector, complete with a pinout table, is provided below:

Positive Connection for DC Power Input or Output:

 

 

Electrically in parallel with the derived DC power for the unit, this pin may be used as a power

4

 

input or output. As a power input it can be used for remote applications to supply the AXIS

 

 

 

2120 via an external direct current source; for example, a 9-15V DC battery supply. Used as a

 

 

power output, it can drive the photo coupled input or other equipment; such as an infrared

3

 

sensor. The output voltage level is dependent upon the input voltage to the unit. A maximum

 

 

 

current of 50mA can be sourced from the DC output.

 

3

Digital Input (photo-coupled anode):

2

 

Voltages 5-24V DC will activate the input. It is possible to use pin 2 to source the input.

 

 

 

 

4

Digital Transistor Output:

1

 

With a maximum load of 100mA and maximum voltage of 24V DC, this output has an

 

open-collector NPN transistor with the emitter connected to pin 1. If it is to be used with an

 

 

external relay, a diode must be connected in parallel with the load for protection against any

 

 

voltage transients - as detailed in the Schematic Diagram, on page 66. Important!

 

 

Connecting AC to the transistor output will damage the unit.
