Serinus 44 User Manual 3.0
RS232 #1
This port is designed to be used for simple RS232 communication.
RS232 #2
This port is designed to be used for simple RS232 communication or in multidrop configuration.
USB
This port can be used for instrument communications with equipment through a standard USB port.
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 instrument is equipped with a maximum of three analog outputs for each measured gas. The
outputs are menu selectable; voltage output (0-5VDC) or current output (0-20, 2-20 or 4-20mA). The
current output can also be configured as a voltage output of 0 to 10V, by configuring the jumpers
(JP3) on the rear panel PCA.
Analog Inputs
The instrument is also equipped with three analog voltage inputs (0-5VDC CAT 1) with resolution of
15 bits plus polarity.
CAUTION
Exceeding these voltages can permanently damage the instrument and void the
warranty.
Digital Status Inputs
The instrument is equipped with eight logic level inputs (0–5VDC CAT 1) for the external control of
zero/span calibration sequences.
CAUTION
Exceeding these voltages can permanently damage the instrument and void the
warranty.
