After connecting a USB cable between your PC and the instrument, ensure their baud
rates match (change the baud rate setting for either your PC's software or the
instrument). Section 5.1.5 shows how to navigate to the baud rate setting in the
Communications Menu where COM2 is the default setup menu for USB configuration.
Also, while there are various communication modes available (Table 5-4), the default
settings are recommended for USB, except to change the baud rate if desired.
Each of the analyzer's serial ports can be configured to operate in a number of different
modes, which are listed in the following table. Each COMM port needs to be configured
independently. Refer to Appendix A for menu trees.
Table 5-4: COMM Port Communication modes
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
1
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
2
communicating with a computer program, such as APICOM.
The Hessen communications protocol is used in some European countries. Teledyne
ML's part number 02252 contains more information on this protocol.
When turned on this mode switches the COMM port settings
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.
When enabled, the serial port requires a password before it will respond. The only
4
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 sending 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
8
transmission handshaking is commonly used with modems or terminal emulation
protocols as well as by Teledyne Instrument's APICOM software.
Improves data transfer rate when one of the COMM ports.
Enables a command prompt when in terminal mode.
