number on the front panel display. For example, if quiet mode (01), computer mode
(02) and Multidrop-Enabled mode (32) are selected, the analyzer would display a
combined MODE ID of 35.
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
1
program where such intermittent messages might cause communication 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

communicating with a computer operated control program.
Protocol for communication with TAI Valve Boxes.
When turned on this mode switches the COMM 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.
When enabled, the serial port requires a password before it will respond (see Section
4
5.5). If not logged on, the only active command is the '?' request for the help screen.
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 installations.
Disables XON/XOFF data flow control also known as software handshaking.
Enables CTS/RTS style hardwired transmission handshaking. This style of data
8
transmission handshaking is commonly used with modems or terminal emulation
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.
COM[1 OR 2]
Communication Modes for each COM port must be configured independently. To turn
on or off the communication modes for either COM1 or COM2, access the
SETUP>MORE>[COM1 or COM2] menu and at the COM1[2] Mode menu press EDIT.
