Data Expansion Head Enhanced Installation

Data Expansion Head Enhanced Radio without Control Head
The Data Expansion Head Enhanced can be used without a control head.
This configuration allows the use of the radio without any control head, allowing the radio to be powered on via the
ignition switch.
The packet data/SDS via the AT commands are available from the 9-pin subD connector (PEI) and from the
Accessory Connector via the USB cable at the same time.
The Remote PTT can be connected via the 26-pin rear connector. Only one talkgroup is available, and that talkgroup
is the first one on the CPS list.
Data Box Radio
This configuration allows the controlling of the radio (Transceiver Box) without NGCH via PEI (for example:
Personal Computer, Laptop, Console, and so on) with AT Commands (recommended) or TNP1 protocol from a
Control Terminal.
In this configuration, the Control Terminal is a substitute for the Enhanced Control Head. The Data Terminal is
connected to either the 9-pin socket of the Data Expansion Head Enhanced via the RS232 cable, or to the 26-pin
accessory connector via the USB cable.
