1.5.13 Communications
Communication between the analyzer and either a data logger, laptop
or network can be performed with the following communication
connections located on the back panel (see Figure 5).
RS232 #1
This port is designed to be used for simple RS232 communication or
with a Termination Panel allowing the Serinus instrument to work as a
datalogger. This function is an optional extra and must be purchased
from Ecotech.
RS232 #2
This port is designed to be used for simple RS232 communication, or
in a daisy chain (multidrop) configuration (multiple analyzers
connected via the same RS232 cable).
USB
This port can be used for instrument communication and is also good
for quickly downloading data, onsite diagnostics and maintenance.
TCP/IP (optional)
This port is best used for remote access and real-time access to
instruments when a network is available to connect with.
External I/O port
The Analog/Digital port sends and receives analog/digital signals to
other devices. These signals are commonly used to activate gas
calibrators or for warning alarms.
Analog Outputs
The analyzer is equipped with three analog outputs. Settable as
either voltage ouput 0-5VDC, or current output 0-20,2-20,4-20
mA
Analog Inputs
The Analyzer is also equipped with three analog voltage inputs
(0-5VDC) with resolution of 15 bits plus polarity.
Warning: Exceeding these voltages can permanently
damage the instruments and void warranty
Digital Status Inputs
The analyzer is equipped with 8 logic level inputs (0–5VDC) for
the external control of Zero/Span calibration sequences.
Warning: Exceeding these voltages can permanently
damage the instruments and void warranty
Digital Status Outputs
The analyzer is equipped with 8 open collector outputs which
will convey instrument status conditions and warning alarms
such as no flow, sample mode, etc.
