COMMUNICATIONS AND REMOTE OPERATION

This instrument's output and communications panel connections include an Ethernet port
and serial communications ports. This section provides pertinent information regarding
communication equipment, the communications ports, and communications protocol. Data
acquisition is set up through the Datalogger (Section 3.3.1).

SING THE OMMUNICATION
The communications ports were described in Section 2.4.1.6, along with their connection
instructions, and their setup instructions were provided in Section 3.3.11. These ports allow
the ability to communicate with, issue commands to, and receive data from the analyzer
through an external computer system or terminal.

ATA ERMINAL
RS-232 was developed for allowing communications between data terminal equipment
(DTE) and data communication equipment (DCE). Basic terminals always fall into the
DTE category whereas modems are always considered DCE devices. The difference
between the two is the pin assignment of the Data Receive and Data Transmit functions,
as previously described in RS-232 Com Port Connector Pin-outs under Section 2.4.1.6.
To enable the analyzer to be used with terminals (DTE), modems (DCE) and computers
(which can be either), a switch mounted on the electrical connections panel, labeled DCE
DTE (Figure 2-3), allows the user to set the RS-232 configuration for one of these two data
devices. This switch exchanges the Receive and Transmit lines on RS-232 emulating a
cross-over or null-modem cable. The switch has no effect on COM2.

Referring to Table 3-5, use the Setup>Comm menu to configure COM1 (labeled RS232
on instrument rear panel) and/or COM2 (labeled COM2 on instrument rear panel) for
communication modes, baud rate and serial communications. If using a USB option
communication connection, setup requires that the instrument's baud rate and personal
computer baud rate match.
