Chapter  6
Communications

Overview

This chapter describes the communications between the instrument and 
another communicating device such as a computer or a printer. You should 
have relevant information about the devices to which the instrument will be 
connected. Some connection examples are included in this manual, 
however, the operation and connection of other devices is outside the scope 
of this manual.

Hardware Interconnection

The instrument has two communication ports:

•

COM-1 RS-232 port on the rear panel (DB9 female connector) 

•

COM-2 RS-485 port on the rear panel (optional) or Ethernet (optional)

The appropriate interface and protocols are selected during calibration.

COM-1 RS-232 Port

The COM-1 RS-232 port provides communication between the instrument 
and one other device such as a host computer or a printer.

Note:

A printer must have a serial port to be able to be directly connected 
to the flow computer. It is not possible to communicate directly with 
a printer via a parallel port.

Computers use either a DB9 or a DB25 connector, and the connections to 
each type are shown in Figure 18.
