6.11. SETUP MORE COMM: SETTING UP THE ANALYSER’S
COMMUNICATION PORTS
The M200EH/EM is equipped with two serial communication ports located on the rear panel (see Figure 3-2).
Both ports operate similarly and give the user the ability to communicate with, issue commands to, and receive
data from the analyzer through an external computer system or terminal. By default, both ports operate on the
RS-232 protocol.
The COM1 port can also be configured to operate in single or RS-232 multidrop mode (option 62; See Section
5.9.2 and 6.11.7).
The COM2 port, can be configured for standard RS-232 operation, half-duplex RS-485 communication or for
access via an LAN by installing the Teledyne Instruments Ethernet interface card (option 63; see Section 5.9.3
and 6.11.6).
A code-activated switch (CAS), can also be used on either port to connect typically between 2 and 16
send/receive instruments (host computer(s) printers, dataloggers, analyzers, monitors, calibrators, etc.) into one
communications hub. Contact Teledyne Instruments sales for more information on CAS systems.
6.11.1. ANALYZER ID
Each type of Teledyne Instruments analyzer is configured with a default ID code. The default ID code for all
M200EH/EM analyzers is
200. The ID number is only important if more than one analyzer is connected to the
same communications channel such as when several analyzers are on the same Ethernet LAN (see Section
6.11.6); in a RS-232 multidrop chain (see Section 6.11.7) or operating over a RS-485 network (see Section
6.11.4). If two analyzers of the same model type are used on one channel, the ID codes of one or both of the
instruments needs to be changed so that they are unique to the instruments. To edit the instrument’s ID code,

The ID can be any 4 digit number and can also be used to identify analyzers in any number of ways (e.g.
location numbers, company asset number, etc.)
