6.9.6. 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 6-17 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 11, the standard configuration on the M100E COM2 port.
Note that each COM port needs to be configured independently.
Table 6-17: COMM Port Communication modes
MODE ID DESCRIPTION
QUIET MODE 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
MODE
2 Computer mode inhibits echoing of typed characters and is used when the
port is communicating with a computer program, such as APICOM.
SECURITY
MODE
4 When enabled, the serial port requires a password before it will respond.
The only command that is active is the help screen (? CR). See Section 6.4.1
for information on using the password feature.
ENABLE
INTERNET
8 Enables the use and configuration of the Ethernet interface. When enabled,
a new menu item INET will appear in the respective COM port menu.
Once this mode is enabled the INET sub menu will appear under the
COMMUNICATIONS MENU (see Menu Tree A-5 in Appendix A-1)
HESSEN
PROTOCOL
16 The Hessen communications protocol is used in some European countries. T-
API part number 02252 contains more information on this protocol.
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.
IGNORE
ERRORS
128 Fixes certain types of parity errors at certain Hessen protocol installations.
DISABLE
XON/XOFF
256 Disables XON/XOFF data flow control.
RS-485 MODE 1024 Configures the COM2 Port for RS-485 communication. RS-485 mode has
precedence over multidrop mode if both are enabled.
COMMAND
PROMPT
4096 Enables a command prompt when in terminal mode.
