Page 8: Function Diagram
Power Supply Modbus configuration 2.4 Design and mode of operation The basis of the DE43 transmitter comprises two piezoresistive sensor ele- ments. The pressure that is to be measured acts upon a silicone membrane that is equipped with a resistor bridge. The acting pressure causes the membrane to move and therefore a change in resistance. -

Up to 123 bus participants can be operated without an amplifier on one strand NOTICE! Star-shaped networks are not allowed.
- Page 12 < 2 A Fig. 15: Intermediate supply Please note that a DE43 with digital inputs has a higher power draw. If the bus participants are equipped with digital inputs, the number of possible bus parti- cipants of a supply circuit are reduced.

4.2 Config select The DE43 Transmitter can be configured using an 8-digit DIP switch. To this end, the sealing plug in the front plate needs to be removed. Below this is an 8- pin DIP switch which can be used to configure both the Modbus address and also the interface. - Page 14 4 | Start-up FISCHER Mess- und Regeltechnik GmbH Baud rate 1200 2400 4800 9600 19200 38400 57600 Parity None Identical parity Not identical parity It is not possible to combine identical or non-identical parity with 2 stopbits.

Page 15: Modbus Functional Description
FISCHER Mess- und Regeltechnik GmbH Start-up | 4 4.3 Modbus functional description The following describes the Modbus functions that support the DE43 Transmit- ter. The descriptions are initially kept general as explained in the Modbus Pro- tocol Specification and are then supplemented with the unique features of the DE43. - Page 16 (N) is the result of the number of inputs divided by 8. If there is a rest, the number of bytes increases (N=N+1). However, as the DE43 only has a maximum of 4 inputs, only 1 byte is trans- ferred as a response.
