Datalogic Scanning DS2400 manual Inputs, Input NPN command using external power

The RTSAUX and CTSAUX signals control data transmission and synchronize the connected devices. If the RTS/CTS handshaking protocol is enabled, the DS2400 activates the RTSAUX output to indicate a message is to be transmitted. The receiving unit activates the CTSAUX input to enable the transmission.

2.4.4 Inputs

The inputs available on the connector supplied with the scanner are the pins relative to the External Trigger, as indicated below:

The External Trigger input is used in the On-Line Operating Mode and tells the scanner to scan for a code. The active state of this input is selected in software. Refer to the WinHost Help On Line.

The yellow LED (Figure A, 2 ) is on when the External Trigger forces a current flow through the EXT TRIG+ and EXT TRIG- pins.

This input is optocoupled and can be driven by both an NPN or PNP type command. The connections are indicated in the following diagrams:
