Each of the analyzer's serial ports can be configured to operate in a number of
different modes, listed in Table 4-9 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
T360 COM2 port.
independently.
Quiet mode suppresses any feedback from the analyzer (DAS 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 inhibits echoing of typed characters and is used when the port is
communicating with a computer program, such as APICOM.
When enabled, the serial port requires a password before it will respond. The only
command that is active is the help screen (? CR).
The Hessen communications protocol is used in some European countries. Teledyne
API's part number 02252 contains more information on this protocol.
When turned on this mode switches the com port settings
Configures the COM2 Port for RS-485 communication. RS-485 mode has precedence
over multidrop mode if both are enabled.
Multidrop protocol allows a multi-instrument configuration on a single communications
channel. Multidrop requires the use of instrument IDs.
Enables to send a modem initialization string at power-up. Asserts certain lines in the
RS-232 port to enable the modem to communicate.
Fixes certain types of parity errors at certain Hessen protocol installations.
Disables XON/XOFF data flow control also known as software handshaking.
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 API's APICOM software.
Improves data transfer rate when on of the com ports.
Enables a command prompt when in terminal mode.
