Example: Below is a simple C program illustrating the Ping (0xA0) Command. This assumes
the presence of a transceiver with an ID of 1 issuing the Ping command and a second
transceiver with an ID of 0x13 (19 decimal) to receive and respond to the Ping command:
2.4 Antenna Switch Control
The antenna switch used on the DLP-RF2-Z is of single-pole, double-throw configuration and is
controlled by microcontroller port pins. The following truth table shows the port pin states
required to enable the transmit and receive functions.
If using the SIPP firmware as shipped from DLP Design, the DLP-RF2-Z will set the correct
mode automatically. This information is only made available in the event that the user wishes to
reprogram the microcontroller with custom firmware.
