Using the Programming Dock

Snap a Carrier Board onto the socket on the Programming Dock as shown

in Figure 8.

Connect a micro USB cable into the connector at the top of the board.

Plug the other end into a PC. The board is powered by the USB bus.

The demonstration software included with the kit or custom application

software can be used to configure the module through its Command

Data Interface. The LCD is used to display information about the module.

This includes the module’s local address and a custom nickname. The

nickname is entered using the development kit software and can be

any name that helps distinguish the modules from one another. This is

convenient when multiple programming docks are connected to the same

computer. Please see the development kit software section for more

information on the nicknames.

The HumRCTM Series transceiver has a serial Command Data Interface

that offers the option to configure and control the transceiver through

software instead of through hardware. This interface consists of a standard

UART with a serial command set. This allows for fewer connections in

applications controlled by a microcontroller as well as for more control and

advanced features than can be offered through hardware pins alone.

Using the Remote Control Demo Board

Snap a Carrier Board onto the socket on each Remote Control Demo

Board as shown in Figure 9.

Insert 4 AAA batteries into the holders on the back of each board, connect

antennas and turn on power.

The modules come paired out of the box, but to Pair additional modules,

press the PAIR button on both boards. The MODE_IND LEDs flash to

indicate that the modules are searching for each other and exchanging

addresses. The MODE_IND has a quick flash while searching (100ms on,

900ms off) and a longer flash once Pairing is complete (400ms on, 100ms

off). This process only takes a few seconds. The pairing process takes the

status line input / output directions into account. If these are changed then

the modules should be paired again.

Once complete, pressing a button on one board (the Initiating Unit or IU)

causes an LED to light up on the other board (the Responding Unit or RU).

The RU sends an acknowledgement message to the IU. If the message is

valid, the IU turns on the CONFIRM LED.

Note: To restore the default configuration, push the PAIR button four

times and hold it down on the fifth press. The MODE_IND LED flashes

when it has reset.
