(purchased separately).] Connection to the RF2-Z for the purpose of setup and test can also be
made via RF from another RF1 or RF2-Z.
**Under this communication protocol, it is the responsibility of the serial host application
firmware to “Retry” transmissions that do not produce the anticipated reply.**
2.1 Packet Structure
Each SIPP firmware packet is comprised of 6 or more bytes. The following table outlines the
packet structure:
PACKET STRUCTURE
*Note: Each transceiver in the system must have a unique ID. ID:0 is reserved for broadcast packets
2.2 Reserved EEPROM Locations
The EEPROM memory is a feature of the SIPP firmware and, as such, is only available if using
the DLP-RF2-Z with its firmware as shipped from DLP Design.
The EEPROM memory used by the SIPP firmware consists of a block of 32 bytes that reside
within the Flash program memory of the MC9S08GT60. The first 10 bytes (0-9) and the last
byte (31) are reserved for storing transceiver settings and checksum. Bytes 10 through 30
(user area) are available for use by user’s host software.
Whenever the data in any EEPROM location is changed, the checksum location (EEPROM
Location 31) is automatically updated. At power up (or reset), if ever the calculated checksum
for the first 31 bytes does not match the value at EEPROM Location 31, the Default Reset
values for the transceiver settings are restored, and the checksum is recalculated and rewritten.
The values in the user area are preserved.
