Ecotech Serinus 44 - 3.4.23 Analog Inputs and 3.4.24 Analog Outputs

Operation
Page 57
[Bayern-Hessen protocol]
Service port (RS232 #1)
Multidrop port (RS232 #2)
The port parameters below are repeated for each serial port.
Serial Delay
Some older communication systems require a delay before the
instrument responds to a serial command. The number of
milliseconds of delay required (0-1000). The default is 0, meaning
the instrument responds as quickly as possible to any serial
request.
Baudrate
Sets the baud rate for this serial port (1200, 2400, 4800, 9600,
14400, 19200, 38400 or 115200).
Protocol
Sets the protocol used for this serial port (Advanced, ModBus,
EC9800 or Bayern-Hessen). This must be set to Advanced for
Ecotech supplied software.
Endian
[Modbus protocol]
Select Little or Big endian mode for ModBus protocol.
3.4.23 Analog Input Menu
Main Menu  Communications Menu  Analog Input Menu
The Serinus supports three analog inputs from the 25 pin I/O connector. Each input is a 0 to 5 volt
CAT 1 input that can be scaled and logged to the USB memory stick or accessed remotely as
parameters 199 to 201.
CAUTION
Exceeding these voltages can permanently damage the instrument and
void the warranty.
Input 1/2/3
The sections below are repeated for each analog input.
Multiplier
The input voltage will be multiplied by this number. For example, if
a sensor has a 0-5V output for a temperature of -40°C to 60°C, the
multiplier would be (60-(-40))/5 = 20.
Offset
This value will be added to the above calculation. Continuing the
example in the multiplier description, the offset should be set to -
40, so that a voltage of 0V will be recorded as -40°C.
Reading
The current reading from the input voltage, after the multiplier
and offset has been applied. This is the value that is logged or
reported as parameter 199 to 201 via USB or serial requests.
