Analog Signals
Analog Output
Most devices include a primary analog output signal, which is linear over its
entire range. For ranges that start at 0 Vdc, a zero-pressure condition is
indicated at approximately 0.010 Vdc. Full scale pressure is indicated by the
top of the range: 5 Vdc for 0-5 Vdc, 10 Vdc for 0-10 Vdc, and so on.
Serial Communication
Establishing Serial Communication
After connecting your flow controller using a communications cable, you will
need to establish serial communications through a real or virtual COM port
on your computer or programmable logic computer (PLC).
• If you have connected your device to a serial port, note its COM port
number. This can be found in Windows® Device Manager.
• If you have a serial to USB adapter, plug it into your computer, ensure the
proper driver is installed, and note the COM port number.
The controller will be configured with the following settings:
• Baud: 19200 (default; others can be used if the computer, its software
and the controller are all set to the same rate)
• Data bits: 8
• Parity: none
• Stop bits: 1
• Flow control: none
Alicat devices use ASCII commands which are easily used in a serial terminal
or integrated into a PLC.
