RuggedCom RX1000 Network Router User Manual


 
Chapter 22 - Configuring Serial Protocols
The Pack Char field configures the numeric value of the ASCII character which will
force forwarding of accumulated data to the network. The Pack Char must be
between 0 and 255 inclusive or the value off. If configured off, accumulated data will
be forwarded based upon the packetization timeout parameter.
The Pack Timer field configures the delay from the last received character until when
data is forwarded. The Pack Timer must be between 5 and 1000 milliseconds
inclusive.
The Turnaround timer field controls the amount of delay (if any) to insert between
the transmissions of individual messages out the serial port. The Pack Timer must be
between 1 and 1000 milliseconds inclusive, of off.
The Call Dir field configures whether to accept an incoming connection, place an
outgoing connection or do both.
The Max Conns field configures the maximum number of incoming connections to
permit when the call direction is incoming.
The Remote IP field configures the address used when placing an outgoing
connection.
The Remote Port field selects the TCP destination port used in outgoing connections.
The Local Port field selects the local TCP port to use to accept incoming
connections.
TcpModBus Menu
This menu configures the TcpModbus settings for each port. Changes are made
immediately.
The Response Timer field configures the maximum time from the last transmitted
character of the outgoing poll until the first character of the response. If the RTU does
not respond in this time the poll will have been considered failed. The Pack Timer
must be between 50 and 1000 milliseconds inclusive.
The Pack Timer field configures the maximum allowable time to wait for a response
to a Modbus request to complete once it has started. The Pack Timer must be between
200 and 1000 milliseconds inclusive.
Note: The Modbus specification states the minimum time is about 640 character times
at baud rates below 19200 Kbps and 256 char times + 192 ms at baud rates above
19200 Kbps. You may specify a larger value if you think your RTU will take longer to
complete transmission than the calculated time.
