Electrical Connection WARNING Incorrect installation, wiring or power supply may cause overheating and therefore personal injuries or damage to property. It is essential that the cables are not under voltage during installation. No voltage must be applied when the product is connected or disconnected. For correct cabling of the device, always observe the presented wiring diagram for the product version used. The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device. Hardware Bus Termination If required, the bus termination shall be realized with 120 Ohm resistor, by the jumper on the PCB. Jumper mounted bus terminated Jumper not mounted bus not terminated Address Setting Address Switch 0 1 00000000 0 1 11010000 Option Address setting via PCS10 Product Configuration Software (= factory setting) All DIP switches at position 0 factory-set default address (245DEC, 0xF5) applicable, can be changed via software (PCS10 or Modbus protocol, permitted values: 1...247). Example: Address is set via configuration software. Address setting via DIP switches DIP switches in any other position than 0 indicate the effective Modbus address which overrules the factory setting and any Modbus address set via PCS10 or Modbus command (permitted values: 1...247). Example: Address set to 11DEC (0000 1011BIN). Modbus Register Map The measurement data is saved as 32 bit float and as 16 bit signed integer values, see the Modbus Register map below. FLOAT32 Parameter Unit Read register: function code 0x03 / 0x04 Temperature T °C, °F3) Relative humidity RH, Uw %RH Register number1) [DEC] 26 28 Register address2) [HEX] 19 1B 1) Register number starts from 1. 2) Register address starts from 0. 3) The choice of measurement units (metric or non-metric) is done at the time of ordering, see the ordering guide in the EE160 data sheet. It is not possible to switch from metric to non-metric or vice versa by means of the PCS.

Switching from metric to non-metric or vice versa using the PCS is not possible. Quick Guide EE160 Modbus Setup Baud rate Data bits Parity Stop bits Modbus address Factory settings 9 600 8 Even 1 245 User selectable values (via PCS) 9 600, 19 200, 38 400, 57 600, 76 800, 115 200 8 None, odd, even 1, 2 1...247 The recommended settings for multiple devices in a Modbus RTU network are 9600, 8, Even, 1. The EE160 represents 1 unit load in a Modbus network. Device address, baud rate, parity and stop bits can be set via: PCS Product Configuration Software and the appropriate configuration cable HA011018. Modbus protocol in the register 1 (0x00) and 2 (0x01). See Application Note Modbus AN0103 (available at www.epluse.com/ee160). The serial number as ASCII-code is located in read-only registers 1 - 8 (0x00 - 0x07, 16 bits per register). The firmware version is located in register 9 (0x08) (bit 15...8 = major release; bit 7...0 = minor release). The sensor name as ASCII-code is located in read-only registers 10 - 17 (0x09 - 0x11, 16 bits per register).
