Databox Expansion Head Installation
This section describes the installation of the Databox Expansion Head for your radio. Ensure that the battery
terminals are removed or the transceiver is turned off during the whole installation.
3.4.1
Databox Expansion Head Radio without Control Head
The Databox Expansion Head can be used without a control head.
This configuration allows the use of your radio without any control head, allowing your radio to be turned on
using the ignition switch.
The packet data or Short Data Service (SDS) using AT commands are available from the 9-pin subD
connector (PEI), and from the Accessory Connector through the USB cable at the same time.
The Remote Push-to-Talk (PTT) can be connected using the 26-pin rear connector. Only one talkgroup is
available, and that talkgroup is the first item on the configuration tool list.
