User manual - INDICATOR TRS-10a
2.
GENERAL CHARACTERISTICS
wall mounted indicator is designed to display digital values and short,
4-letter messages. This superior system makes the display flicker when a displayed value is
not refreshed. It is a slave device that communicates with the Master device via RS 485
interface with Modbus RTU protocol. The indicator is dedicated to the TRS system (multipoint
temperature and humidity recording system), but it can cooperate with any superior system
equipped with RS 485 link with Modbus RTU protocol. It has a small plastic casing.
