6.8.5. Setting the Serial I/O Communication Mode

The analyzer has several operation modes available to use with its Serial I/O
communication ports. These are:
Feature
QUIET MODE
COMPUTER
MODE
SECURITY
MODE
HESSEN
PROTOCOL
RS-485 MODE
MULTIDROP
PROTOCOL
ENABLE
MODEM

PROMPT
More than one mode can be turned on at the same time by adding the mode
numbers.
MODE ID NUMBER: This is a unique number that identifies the mode(s), which have
been selected. This sum of the ID numbers of all of the modes that have been
selected is displayed in the Message field of the Front Panel Display at the start of
the Com set up routine.

Table 6–15: COMM Port Communication Modes
Mode
ID #
1 Quiet Mode – used when port is communicating with a computer
program, such as APIcom. Suppresses reports, and warning messages.
These are available, but a command must be issued to receive them.
2 Computer Mode – inhibits echoing of characters, and the edit keys. Used
when the port is communicating with a computer program, such as
APIcom.
4 When enabled, the serial port requires a password before it will respond.
The only command that is active is the help screen (? CRLF). See
Section 6.3.3 to set up the password.
16 The Hessen protocol is used in some European countries to acquire data
from the M300E.
1024 Configures the Com Port for RS-485 style communication. RS-485 mode
has precedence over Multidrop mode if both are enabled.
32 Multidrop protocol – modifies the default T-API protocol to allow the use
of an ID number in every command – used in multi-instrument
configurations with a single serial communications link.
64 Enables the sending of a modem initialization string at power-up.
Asserts certain lines in the RS-232 port to enable the modem to
communicate.
8 Configures the com port to support ethernet interface.
128 Fixes certain types of parity errors at certain Hessen protocol
installations.
256 Disables XON/XOFF flow control.
4096 Enables a command prompt when in terminal mode.
