DocumentDocument1. Short description TSM400-4-CPTH is a multi-sensor that supports MODBUS RTU protocol over the RS-485 interface. The sensor measures CO2 concentration, temperature, humidity, and barometric pressure. The MODBUS device integrates an advanced non-dispersive infrared sensing element (NDIR) for CO2 measurements. The measurement principle is based on the absorption of infra-red (IR) light with specific wavelengths by CO2 molecules. The carbon dioxide sensing element is temperature compensated for better accuracy. Self-calibration is available for carbon dioxide measurements. It is done if the sensor is left in fresh (around 400 ppm CO2 concentration) air. The basic sensing element for barometric pressure is factory calibrated and it does not require any lifetime recalibration. A unique capacitive element is used for measuring relative Humidity while the temperature is measured by a band gap sensor. Both sensors are seamlessly coupled to a 12-bit analog to digital-converter. This results in superior signal quality. The TSM400-4-CPTH multi-sensor is housed in a slim plastic enclosure. The bottom part of the enclosure is suitable for installation on standard flush-mounted/cavity wall boxes ø68mm, with installation openings on 61 mm. 2.

Installation Two-Wire MODBUS definition according to modbus.org: "A MODBUS solution over a serial line should implement a "Two-Wire" electrical interface in accordance with EIA/TIA-485 standard. On such a "Two-Wire" topology, at any time one driver only has the right for transmitting. In fact, a third conductor must also interconnect all the devices of the bus - the common." TSM400-4-CPTH_R1.0 August 2022 Page 3 Attention: For proper operation of the interface, terminators (120 ohms resistors) must be installed at both ends of the bus. The device has a built-in 120-ohm resistor and to terminate the line, "B-" and "TERM" must be shortened. A daisy-chained (linear) topology for multiple sensors should be used. UTP/FTP cables are mandatory for interconnection. 7. Installation tips The location and the mounting position of the sensor have a direct effect on the accuracy of the measurement. The tips below will ensure good measuring results: · Sensor shall be installed about 1.2-1.4 m above the floor; · To avoid solar radiation, the sensor should not be installed next to windows or directly in the sunlight; · Sensors shall be installed in a place with sufficient air circulation. TSM400-4-CPTH sensor is intended for installation on a cavity wall box with 68mm diameter and 61 mm screw spacing. TSM400-4-CPTH_R1.0 August 2022 Page 4 8. Status indicator The status of the device is shown by a single LED, located inside the box: · If the LED blinks for a period of 1 second, the sensor works properly; · If the LED blinks for a period of 3 seconds, there isn`t communication with the controller; · If LED doesn`t blink, there isn`t a power supply. 9. Factory default settings Disconnect the sensor from the bus (switch off the power supply). Press and hold the "config" button. Don't release the button, connecting the sensor to the bus (switch on the power supply). The "status" LED will be ON for 3 seconds and after this will flash for 7 seconds. After the 10-th second the LED will be ON. Release the button. The sensor will restart with factory default settings. 10. Firmware update The firmware of the sensor can be updated with a Teracom controller which supports MODBUS RTU or MBRTU-Config software.
