Table 0-17: COM 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). Section 6.4.1 describes
the password functionality.
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.
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.
512 Unused
RS-485
mode 1024 Configures the COM2 Port for RS-485 communication. RS-485 mode has
precedence over multidrop mode if both are enabled.
E, 7, 1 2048 This setting selects even parity, 7 data bits, and 1 stop bit for this com port;
the default setting is always no parity, 8 data bits, and 1 stop bit. Used in
conjunction with the Hessen protocol, hence, it is listed after ID 16
Command
Prompt 4096 Enables a command prompt when in terminal mode.
Each Parameter is preceded by a string of either COM1 or COM2 depending on the chosen
COM port.
