Channel values are transmitted sequentially every 16 seconds
Dip switch selectable service packets
Unique serial number for each channel based on root serial number of IAU
Integrated 100 mw, 900 MHz./2.4 GHz radio network interface
Internal antenna for 900 MHz. or 2.4 GHz. radios
Phoenix screw terminals on all connections.
Reverse tolerant, thermal and over voltage protected AC/DC input power.
Dimensions 130 x 130 x 75 MM.
Enclosure range-of material: - 40 °C - + 120 °C.
Enclosure temperature range in cont. use: 80 °C.

Description:
Point Six Receivers, Servers and Repeaters receive process and perform a CRC-16 error check on this data packet. If the data is not accurate it is discarded.
When a packet is received that is error free it is converted to a 29-character string and transmitted out the serial port (usually at 19,200 Baud). A checksum byte is added so that data is easier to error check. The data is transmitted serially in ASCII Hex format and terminated with a CR character. This format requires two bytes for each byte of data; 14 data bytes x 2=28 plus the CR is 29 characters
