Data Management Parameters
Termination Character
When receiving characters from the RS-232 interface, receipt of this character will cause buffered data to be sent over the
TCP connection. If no character is defined buffered data is transmitted based on maximum block size or character timer
(defined below).
Block check length
In many cases, there are 1 or 2 bytes of CRC or LRC after a termination character is received and it is usually desirable to
have those bytes included in the same packet with the data. This field allows the PAD to buffer those block check bytes
before acting on the termination character.
Transmit timer
In the case where the router has buffered transmit data, has not reached the maximum block size, and has not received a
termination character, it will transmit the buffered data if it does not receive a character from the RS-232 interface in this
period of time. For instance, if this timer is set to 200msc, every time another character is received this timer is reset to
200msc. If the timer expires before the next character is received all buffered data is transmitted.
Maximum Block Size
If router receives this many characters without a timeout or without a termination character the buffered data will be
transmitted.
