3 Installation
The installation of the PTC is simple. You only need to correctly configure the cable between
the PTC, the computer and the transceiver, if this is not already available.
3.1 Power supply
The PTC-IIIusb has two inputs for its power connections which can be used alternatively.
Either connect via the DC-in supply socket at the rear of the unit, or via the connector for the
short-wave transceiver (Audio, pin 5). Both connections are decoupled with diodes and
protected against reverse polarity. An input voltage between 10…20 VDC is allowed. The
current consumption is usually around 200 mA at 13.8 V. The power supply inputs on the PTC
are especially filtered so that harmonics of the switch- mode regulator cannot pass to the
outside of the unit. The inputs are also protected by a self-resetting fuse.
3.2 USB
The PTC-IIIusb is a USB 1.1 device and can be operated in an USB 2.0 environment as well.
The connection to the computer is done with the attached USB cable.
For USB operation an appropriate driver needs to be installed on your computer. This driver is
on the
SCS
-CD that comes with the modem.
Below you find a short description on how to install the driver on Windows XP (Service Pack
2). With earlier Windows-versions the installation runs in a similar way.

To the first question if Windows shall connect to “Windows Update to search for new
software” you answer with “No, not this time” and then click on “Next”
x
The wizzard now wants to install the driver for the
SCS
Radio Modem Device. Select the
option “Install the software automatically” and click “Next”
