Input Specifications

The current JS-25 scanners have two connectors: an LTW Industrial Sealed Ethernet, and a iConn 8-conductor circular sealed connector. The 8-conductor connector is used to supply power as well as encoder and synchronization signals to the JS-20 scanner.

The encoder inputs are RS-422 5-V differential signals. They support encoder rates up to a maximum of 100,000 pulses per second.

The Start Scan input signal can be driven by either RS-422 5V differential, 5V push pull, or open collector outputs.  For 5V push-pull and open collector operation, the input should be to the StartScan+ signals, and the StartScan- should be left floating. The Start Scan signal is edge triggered, and by default triggers on a falling edge. The StartScanTriggerOnHigh parameter reverses this, and causes the scanners to trigger on a rising edge.

8-Wire Pinout

JS-25 scanners are generally connected with our standard 8 wire cable. Alpha 2643C or an equivalent cable is suggested.
