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.
3.4.25 Analog Input Menu
Main Menu → Communications Menu → Analog Input Menu
The Serinus supports three analog inputs from the analog & digital I/O port. Each input is a 0 - 5 volt
CAT 1 input that can be scaled and logged to the USB memory stick or accessed remotely as parameters
199 - 201.
CAUTION
Exceeding these voltages can permanently damage the instrument and void the
warranty.
Figure 67 – Analog Input Menu Screen
Input 1 is CO2
When enabled several new menu items appear in other menus
and the home screen now displays the CO and CO
2
gas
concentrations.
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 - 5 V output for a temperature of
-40 °C to 60 °C, the multiplier would be (60 - (-40))/5 = 20.
