Analyzer Id; Com Port Default Settings - Teledyne 200E Instruction Manual

Model 200E Instruction Manual
however, can be configured for half-duplex RS-485 communication or can be used for the
T-API Ethernet interface card (optional equipment, Section 5.6.3).
There are two options to connect multiple analyzers to a single computer terminal or data
logging device over a single serial communications line. Either port can be equipped with an
optional RS-232 multidrop assembly (Section 5.6.2), or up to eight analyzers can be
connected using COM2 configured for RS-485 operation (contact the factory for further
information). A third option is to use a code-activated switch (CAS), which can connect
typically between 2 and 16 analyzers to one communications hub. Contact T-API sales for
more information on CAS systems.
When equipped with the optional Ethernet interface (Section 5.7.3), the analyzer can be
connected to any standard 10BaseT Ethernet network via low-cost network hubs, switches
or routers. The interface operates as a standard TCP/IP device on port 3000. This allows a
remote computer to connect through the internet to the analyzer using APIcom, terminal
emulators or other programs.

6.9.1. Analyzer ID

The first entry in the COMM menu is for configuration of the analyzer ID number, a
numerical value of up to 4 digits. As a factory default, the M200E is configured with ID
number "200". The ID number is only important if more than one analyzer is connected to
the same communications channel (e.g., a multi-drop setup), in which case each analyzer
needs to be addressed with a unique ID number. Different models of T-API analyzers have
different ID numbers, but if two identical models are used on one channel (for example, two
M200E instruments), the ID of one instrument needs to be changed. The ID can also be
used for internal identification of same model analyzers in different locations.
For the Hessen protocol (a configuration option listed in Table 6-17 and briefly described in
Section 6.9.10), the M200E assigns different numbers to identify its reported gases. When
this protocol is enabled, the analyzer behaves and reports as three separate instruments,
one for each gas.

6.9.2. COM Port Default Settings

As received from the factory, the analyzer is set up to emulate a DCE or modem, with pin 3
of the DB-9 connector designated for receiving data and pin 2 designated for sending data.
• COM1: RS-232 (fixed), DB-9 male connector.
• Baud rate: 19200 bits per second (baud).
• Data Bits: 8 data bits with 1 stop bit, no start bit.
• Parity: None.
• COM2: RS-232 (configurable), DB-9 female connector.
• Baud rate: 115000 bits per second (baud).
• Data Bits: 8 data bits with 1 stop bit, no start bit.
• Parity: None.
