DESCRIPTION
QUIET
1
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.

The Hessen communications protocol is used in some European countries. Teledyne
API’s part number 02252 contains more information on this protocol.

2048
Allows the COMM port settings to be set between either
No parity; 8 data bits; 1 stop bit (ON/OFF)
to
Even parity; 7 data bits; 1 stop bit (ON/OFF)
RS-485
1024
Configures the COM2 Port for RS-485 communication. RS-485 mode has precedence
over Multidrop mode if both are enabled. When the COM2 port is configured for RS-485
communication, the rear panel USB port is disabled.
over Multidrop mode if both are enabled. When the COM2 port is configured for RS-485
communication, the rear panel USB port is disabled.
SECURITY
4
When enabled, the serial port requires a password before it will respond. 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.

Disables XON/XOFF data flow control also known as software handshaking.
HARDWARE
HANDSHAKE
8
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 Instrument’s APICOM software.
