2 Supporting Ping Pong Range Test on Host Board

See the Development Kit User’s Guide for detailed information

regarding Ping Pong Range Test usage.

The Ping Pong Range Test firmware is built into the module firmware. This allows for

the test to be used on the application host board. The following considerations need to

be made in order to utilize the test.

2.1.1 Power

A nominal 3.3 VDC power supply should be connected to the VCC - 3V3DC pin (26) on

the module. Also, a ground connection on the GND pin (44) is required. If batteries are

used be sure to install the jumper on J2 between pins 2-3.

2.1.2 LED’s

Three LEDs should be connected to module pins 27-29. The cathode of each LED

should be each pin. The anode of each LED should be connected to the 3.3 V power

supply through a nominal resistor value in the range of 180 to 470 ohms. Module pin 27

should connect to a green LED, pin 28 should connect to a yellow LED, and pin 29 to a

red LED.

2.1.3 Switches

Module pin 31 should be connected to ground through a normally open tact switch. In

addition a 10k ohm pull-up resistor to VCC should be connected to this pin as well. This

switch is referred to as the USER1 button in the subsequent instructions.

Also, the RESET pin should be connected to ground through a momentary contact

normally open (NO) push button switch. This switch is referred to as the RESET button

in the subsequent instructions.
