Appendix B

Checksum Checksum is optional. It is calculated as a sum of all bytes of the

message starting with start byte and ending with checksum

identi er. Checksum is transmitted as a sequence of 3 bytes,

where 1st byte is (hundreds+0xCD), 2nd byte is (tens+0xCD) and

3rd byte is (units+0xCD). For example, checksum=137 will be

transmitted as:

0xCE, 0xD0, 0xD4

TCP/IP PROTOCOL

Notice: Lyntec RPC ﬁ rmware version 1.18a or later

is required to implement this scheme. For technical

assistance please call 800-724-4047.

TCP/IP communications and control via a third party control

system is facilitated by the use of the HTTP GET command.

Example of GET command:

GET /p2.rpc?IPB002=1

Three modes of control are:

Breaker control = “B” Zone control = “Z” Event Control = “E”

Refer to LynTec RPC browser set-up for breaker numbering

GET /p2.rpc?IPB002=1

This control string will turn breaker #2 on.

GET /p2.rpc?IPB002=0

This control string will turn breaker #2 o .

Control of up to 167 breakers (4 panel system) is possible.

Con gure your zones (breaker groups) using the LynTec RPC

browser set-up when connected to the LynTec RPC panel.

GET /p2.rpc?IPZ002=1

This control string will turn zone #2 on.

GET /p2.rpc?IPZ002=0

This control string will turn zone #2 o .

Zone Control = Z

Breaker Control = B
