Dispatch Str. 1 & Dispatch Str. 2
Default: 0000H
This mode allows compact sending of serial data to the
network; the serial data stream is not broken down
randomly, rather serial packets can be transferred over the
network in their original context as a packet.
In Dispatch Str. 1 and/or Dispatch Str. 2 enter in
hexadecimal format two characters each to be used for
finding the serial data stream. Only when one of the two
strings has been found are the data packed into network
packets by the serial port. If only one character is to be
searched for,
Dispatch Str. 2 must be set to 0000 . If you for
example configure Dispatch Str. 1 to 3100 and Dispatch
Str. 2 to 0000 , only the ASCII character 1 will be searched
for.
Format: 16-bit integer hexadecimal, Host-Order (leading
Low-Byte)
13.1.3 Deactivating Box-to-Box mode
Just as in the case of configuration, Box-to Box mode only
needs to be deactivated at the Master port in order to properly
close the TCP connection. The Slave port and the Master port
must both be located on the Ethernet.
