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.

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 3 to 5.
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 3 to 5 via USB or serial
requests.

Output Mode The analog output can be set to be either Current or Voltage .
Different fields will be displayed depending on which analog

NO2 The name of the gas for each analog output. All of the fields
below are repeated for each gas.
