to an A/D channel of the PIC18F1320. Changing the temperature of this device
will effect the ”temperature” value that is transmitted to the Primary device.
The DSR and CTS LEDs will immediately turn off and the PHACT LED will turn
on in about 10 seconds.
OPERATING THE “TRANSMIT TEMPERATURE” PROGRAM
Temperature value transmitted by the PIC18F1320 will be dependent on
battery voltage (see Section 2.3.2.2 ““Transmit Temperature” Program
Description”).
