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. TAI
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.
