3.2. Outline of Host Station (Transmitter) Operations

The host station is configured using a transceiver and a PC connected to the
network. Data signals that control the transceiver are connected to the PC using
either LAN, USB or RS-232C. The PC uses its sound function to input and output
audio transmitted and received by the transceiver, and converts them between
digital and analog signals.
The ARHP-990 is installed on the PC. In the case of use via the Internet, VoIP
Program is installed on the PC. The ARHP-990 exchanges transceiver control
data signals with the network. The VoIP Program exchanges audio
transmissions with the network.
The PC is connected to the network, and exchanges transceiver control data
signals and audio transmissions with the "Remote station (operator)" on the
network.

Connection LAN, USB
or
RS-232C
Audio
Controls that change the frequency or mode are
performed by connecting the transceiver and PC
using either a USB cable or RS-232C cable. (The
transceiver has only one RS-232C connector, so if
you are using the RS-232C connector for KNS
operations, another device cannot be connected.)
There is also a way to connect both the transceiver
and PC to the home LAN. Since the transceiver
control communication is high-speed, this method is
recommended.
The audio cable is created by the user.
To exchange audio transmissions, connect the
transceiver ACC2 connector to the PC sound I/O
terminal. For the transceiver connector
specifications, refer to the TS-990S instruction
manual, and for the cable creation and connection
methods, refer to "4.2. Connecting an Audio
6
Cable".
