TCP/IP Response
The TCP/IP Response allows the user to select the Response Time (in seconds) to allow for the Unit to respond to
Programming Commands over a TCP/IP Connection. The value of this may require the use of the About Utility. By pinging
the destination IP Address, the utility will give back Minimum / Maximum / Average Times it takes to send and receive a
packet over the TCP/IP Connection. A safe value will be to use the Maximum Time (in seconds).
DMP Baud Rate
DMP Baud Rate selects the communication speed for the Primary and Secondary COM Ports when using the DMP protocol.
This protocol is used to talk to the Integra modems through the Setup Port.
SYNC/ESC Framing
A typical SYNC/ESC frame will look like the following character stream.
SYNC ML Data0 ------ DataN Chksum
8 bits 8 bits 8 bits ------ 8 bits 8 bits
And the following definitions are made:
SYNC (8 bits)
Marks the start of a frame when not preceded by and ESC character. When using a Sync/Esc (Framing) Mode, the software
will stuff this character automatically.
ML (8 bits)
The length of frame is given by ML. ML is the number of characters left to be received including the checksum but excluding
any ESC characters added as part of the protocol. When using a SYNC/ESC (Framing) Mode, the software will stuff this
character automatically (based on the number of data characters).
Data 0 - N (8 bits each)
Frame information.
Chksum (8 bits)
This is the 8 bit 2s complement of the sum of the frame less the SYNC character and any additional ESC characters added
(ignoring the carry out of the high order bits. When using a SYNC/ESC (Framing) Mode, the software will stuff this character
automatically.
3.4.11 SWAP COM PORTS
Selecting Swap Com Ports from the Utilities drop-down menu moves the Secondary COM Port settings to the Primary COM
Port (and moves the Primary COM Port to the Secondary settings). Since Integra-TR programming is done through the
Primary COM Port, this is useful when two units are connected to the Primary and Secondary COM Ports. A Swap COM
