In this video, we will demonstrate how to set up communication for several types of sensors, as well as the settings you can use to customize your sensor for your application.
Thank you for choosing Automation Products Group for your sensor and monitoring needs. If you’ve purchased an RS-485 sensor from Automation Products Group, you already know that the versatility and convenience of sensor interface communication is invaluable in a world of increasingly automated industries. The ability to monitor and log readings, and alter sensor settings from a network location, saves both time and money.
00:22 APG MODBUS IS THE HUB FOR RS-485 COMMUNICATION
APG Modbus is the hub for RS-485 communication with your sensors. Using APG Modbus, you can change everything from communication baud rate to the custom labels for your sensors.

00:51 PRODUCTS WITH RS-485 COMMUNICATION
To communicate with APG Modbus, several APG products such as the RST interface series or DCR-1006A are available with RS-485 communication. The RST-4100 is designed for use with an MPX sensor with Hart communication. There are also a variety of other RS-485 USB adapters available from other manufacturers.
01:28 CHECK YOUR SENSOR WIRING INFORMATION
To begin, check your sensor wiring information and wire the sensor to your RS-485 communication device according to the A-B wiring configuration.
01:40 POWER YOUR SENSOR
Your sensor will also need to be powered in order to operate. This can be done with an external power supply or, in the case of a DCR-1006A, with the included 24-volt power line.
01:55 MPX WIRING NOTE
Please note that if you are wiring an MPX, a 120-ohm resistor must be installed between the A and B terminals of the sensor. If you are wiring multiple MPX sensors in a daisy chain, the resistor must be placed between the A and B terminals of the last sensor in the chain. If you are using a communication device other than an RST-6001, a 120-ohm resistor must also be installed between the A and B terminals of the RS-485 device.
The RST-6001 has this resistor installed internally. If you are programming an MPX with 4-20 milliamp output, a 150 to 700-ohm load resistor must be installed in series between the RST and the positive power terminal.
