Model 8314-X IM-477
3. COMMUNICATIONS:
The system provides both RS-232 serial port and 10BaseT Ethernet operation.
The RS-232 port can operate at 9600, 19200, 38400, or 57600 baud rates, selectable via internal DIP switch.
Default format is 9600N81. The serial port uses a standard DB9 DTE connector pinout. Connection to a standard
PC’s serial port requires the use of a “null-modem” type cable to swap the transmit and receive data pair (pins 2 and
3). A command-line interface (CLI) will be provided for interactive use w/ a terminal emulator. The CLI can be disabled
to facilitate use of the serial port as a programming interface. The CLI provides user prompts and supports simple line
editing (via the BS key) , last command recall (Ctrl-P), and a simple help facility. Help can be accessed from the main
command prompt using either the HELP or simply ‘?’. Additional help for many commands is available by specifying
the main command followed by a ‘?’. For example, “SET ?” provides a list of the SET commands, and “SET FREQ ?”
provides detailed info on the set frequency command.
Many commands and keywords allow abbreviated forms. Command abbreviations can be displayed using the
‘CMD ?’ help command. Also, there are some system level configuration/diagnostic commands, such as PING, that
can be listed using ‘SYS ?’ help command. Many of these require system-level password access.
10BaseT Ethernet will provide TELNET access (port 23) to the CLI for operation over a network. In addition,
TFTP client will also be supported for performing code updates to the flash memory. Network parameters (IP address,
subnet mask, TFTP host address, etc) can be set and stored/recalled from non-volatile memory. TFTP transfer is also
used to support the download/upload of the raw data tables, due to the potential volume of information to be
transferred. By default, the unit is configured for an IP address of 10.0.0.1, with a subnet mask of 255.255.255.0.
A NOTE ON PASSWORDS
Passwords are/can be used to prevent inadvertent configuration/switch changes. Password
protection is, generally, weak, in that a user can see the current password using the ‘SHOW CONFIG’
command. In addition, there is a fixed password (the word SYSTEM) that can be used that will grant
system-level access to many commands normally reserved for system testing/configuration.
