6.9. Setup - Communication Ports (COMM)
The M100E is equipped with two serial communication ports located on the rear panel
(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
COM2 port, however, can be configured for half-duplex RS-485 communication or can be
used for the T-API Ethernet interface card (optional equipment, Section 5.5.3).
Multidrop Communications
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 5.5.2), 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.
Ethernet Communications
When equipped with the optional Ethernet interface, 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 M100E 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 M100E 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), the M100E assigns
three numbers to identify its three reported gases: 211 for SO
2
, 212 for SO
2
and 213 for
NO
2
. When this protocol is enabled, the analyzer behaves and reports as three separate
instruments, one for each gas.
