10.0 Output Signals
The MCT has the following signal interfaces available for connection to other devices.
Analog Outputs: Three 0–10 volts isolated.
Three 4-20mA isolated.
Load resistance 500 ohms Max.
Hold/Gated Input: Facility for a contact closure input indicating a gap in the stream of product on the
conveyor. When activated the sensors display and analog output signals will be
“frozen” for the time the hold input is active.
10.1 Serial Communications
The Sensor provides a choice of serial output formats, RS232 and RS485.
RS232 is suitable for a single sensor to computer connection over a distance of up to 100 feet (30
meters).
RS485 is suitable for connection of up to 16 sensors on a cable up to 3 miles (4.86Km) long.
10.1.1 Serial Requirements
1. RS232/485: Baud Rate: 300 to 38400 (9600 default)
Parity: None
Data Bits: 8
Stop Bits: 1
2. Cables: RS 232: 9 pin ‘D’ serial cable wired pin to pin
RS 485: Shielded twisted pair.
