Serial port settings
•
Disable
The serial port is not assigned GPS or PAD functionality.
When Disabled, the port is free for use.
•
External pad
The serial port will be bridged to the configured TCP port,
providing access to serial devices over the WAN.
Serial port configuration
•
Electrical interface
Sets the serial port to use either RS-232 or RS-485.
RS-485 is a balanced electrical interface suited for
multi-drop applications, such as communication over long
cable distances or in noisy environments. When RS-485 is
selected, the Flow Control option becomes unavailable.
•
Power selection
Select voltage present on pin 9 of the COM 1 DB-9 serial
connector. This voltage can be used to power any serial
devices connected to COM 1.
•
Baud
Select the serial port baud.
•
Data bits
Select the number of data bits per character: 5, 6, 7, or 8.
•
Stop bits
Select the number of stop bits per character: 1 or 2.
•
Parity
Select the type of parity per character: None,
Even or Odd.
•
Flow control
Select the type of flow control: None, or Hardware
(RTS/CTS).
•
DSR
Select how the DSR handshake line should be handled:
Always On, On When Connected, On When Available, or
Always Off.
•
DCD
Select how the DCD handshake line should be handled:
Always On, On When Connected, or Always Off.
External PAD configuration
The mode selection configures the service to listen on
configured TCP or UDP port or connect to an external host
as a TCP client.
•
Mode
The TCP server and UDP modes will listen on the
configured port for connections from the Friendly IP
address. The TCP client will attempt to connect to the
configured Remote IP address on the Remote Port.
•
Friendly/remote IP address
TCP/UDP server
: Sets the IP address of the client that
is allowed to connect to the PAD service.
TCP Client
: The remote host address.
•
Inactivity/respawn timeout
Time after which the current connection with Client will
be terminated without warning. This time starts over
again each time the Client sends data to the server. The
timeout is between 1-120 seconds. Enter 0 for
no timeout.
•
Log
When enabled, as data passes through the PAD, a copy
is stored in an internal log file.
•
Log type
Exposed when Log is enabled, provides the option of
logging characters in either ASCII or Hex.
PAD log
If PAD Log is enabled, the current log can be displayed from
this tab.
