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.
