2.2 Operational Overview

The quick start demonstration presented in this chapter is referred to as the

ping pong test. The ping pong test allows an end user to easily verify

communication between two transceivers and get a feel for the quality of the

link via feedback of the flashing LEDs.

Operation involves two boards, with one designated as a master device and

the other as a slave device. The master periodically transmits packets to the

slave. If the slave receives and verifies the packet, it will flash its LEDs and

transmit an acknowledgement to the master. If the master receives and

verifies the acknowledgement, it will flash its LEDs.

In normal ping pong mode, LEDs indicate signal strength (two LEDs on

indicate high signal strength, one LED indicates low signal strength). If the

LEDs do not light, the packet or acknowledgement was not received.

2.2.1 Power Up

Insert batteries into interface boards and verify that battery supply is selected

using the jumper as shown in Figure 2-3 below (J43 1-2, J18 4-6, J16 5-6,

J16 9-10, and J36 1-2).
