Power and Communications Module (PCM) - Optional
The PCM (Figure 4) connects directly to the S5 or M9 using a 1-m cable. It provides power to
the ADP using a rechargeable battery pack. It allows for remote communications with a PC or
Mobile device via a radio link. There are two different radio communications options depending
on range.

The PCM has four LEDs. Table 1 describes their purpose. In all cases, a green light would indi-
cate that the component is functioning while a red/orange light would indicate that the system is
not functioning. Below is a description for the LED labels.

Bluetooth Option
A PCM with the Bluetooth option provides remote communication between the ADP and PC or
Mobile device. The maximum range using the supplied Bluetooth dongle plugged into a PC is
up to 200m. The Bluetooth range of the Mobile device is approximately 60m. Those approxi-
mate ranges assume a clear line-of-sight with no obstructions or poor weather.
