6.10.8. COM Port Communication Modes
Each of the analyzer’s serial ports can be configured to operate in a number of different modes,
which are listed in Table 6-18 and which can be combined by adding the Mode ID numbers. For
example, quiet mode, computer mode and internet-enabled mode would carry a combined mode
ID of 1, the standard configuration on the M6200E COM2 port. Note that each COM port needs to
be configured independently.
Table 6-18: COMM Port Communication modes
MODE 1 ID DESCRIPTION
QUIET
1
Quiet mode suppresses any feedback from the analyzer (iDAS reports, and
warning messages) to the remote device and is typically used when the port
is communicating with a computer program such as APICOM. Such feedback
is still available but a command must be issued to receive them.
COMPUTER
2
Computer mode inhibits echoing of typed characters and is used when the
port is communicating with a computer program, such as APICOM.
SECURITY
4
When enabled, the serial port requires a password before it will respond.
The only command that is active is the help screen (? CR).
HESSEN
PROTOCOL 16
The Hessen communications protocol is used in some European countries.
Teledyne Analytical Instruments part number 02252 contains more
information on this protocol.
E, 7, 1
2048
When turned on this mode switches the COMM port settings
from
No parity; 8 data bits; 1 stop bit
to
Even parity; 7 data bits; 1 stop bit
RS-485
1024
Configures the COM2 Port for RS-485 communication. RS-485 mode has
precedence over multidrop mode if both are enabled.
MULTIDROP
PROTOCOL
32
Multidrop protocol allows a multi-instrument configuration on a single
communications channel. Multidrop requires the use of instrument IDs.
ENABLE
MODEM
64
Enables to send a modem initialization string at power-up. Asserts certain
lines in the RS-232 port to enable the modem to communicate.
ERROR
CHECKING 2
128
Fixes certain types of parity errors at certain Hessen protocol installations.
XON/XOFF
HANDSHAKE 2
256
Disables XON/XOFF data flow control also known as software handshaking.
HARDWARE
HANDSHAKE 8
Enables CTS/RTS style hardwired transmission handshaking. This style of
data transmission handshaking is commonly used with modems or terminal
emulation protocols as well as by Teledyne Instrument’s APICOM software.
HARDWARE
FIFO 2
512
Improves data transfer rate when on of the COMM ports.
COMMAND
PROMPT
4096
Enables a command prompt when in terminal mode.
