Each of the analyzer‟s serial ports can be configured to operate in a number of different
modes, listed in Table 6-1. As modes are selected, the analyzer sums the mode ID
numbers and displays this combined number on the front panel display. For example, if
quiet mode (01), computer mode (02) and Multi-Drop-Enabled mode (32) are selected,
the analyzer would display a combined MODE ID of 35.
ID
Quiet mode suppresses any feedback from the analyzer (such as warning messages)
to the remote device and is typically used when the port is communicating with a
computer program where such intermittent messages might cause communication
1
problems.
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
2
communicating with a computer operated control program.
The Hessen communications protocol is used in some European countries. TAPI P/N
02252 contains more information on this protocol.
When turned on this mode switches the COM port settings from
No parity; 8 data bits; 1 stop bit to Even parity; 8 data bits; 1 stop bit.
When turned on this mode switches the COM port settings from
No parity; 8 data bits; 1 stop bit to Even parity; 7 data bits; 1 stop bit.
Configures the COM2 Port for RS-485 communication. RS-485 mode has precedence
over multidrop mode if both are enabled. Also, configuring for RS-485 disables the rear
panel USB port.
When enabled, the serial port requires a password before it will respond (see Section
4
5.5). The only command that is active is the help screen (? CR).
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
8
protocols as well as by Teledyne Instrument's APICOM software.
Disables the HARDWARE FIFO (First In – First Out). When FIFO is enabled, it
improves data transfer rate for that COM port.
Enables a command prompt when in terminal mode.
