Overview
The PK-232SC is the latest generation of multimode data controllers built upon the solid
foundation of the legendary PK-232. The PK-232SC features an expanded interface to
connect and control your radio transceiver, station accessories and computer.
The key to the new PK-232SC is a single USB cable from your PK-232SC to your
computer. No other connection is necessary. Note the PK-232SC block diagram in
Figure 1. The USB cable from the computer connects to a four port USB hub inside the
PK-232.
Port 1 of the USB hub connects to a dual USB-to-UART bridge.
One of the UART serial ports connects directly to the PK-232SC UART serial port. This
shows up on your computer as a standard COM port. Your software terminal program
connects to this COM port to control the PK-232SC.
The other UART serial port is the rig control port. This optically isolated port supports
Icom CI-V, Yaesu CAT, Kenwood logic level, and RS-232 connections. This shows up
on your computer as an enhanced COM port. Your software rig control program controls
your transceiver.
Port 2 of the USB hub connects to a USB Audio sound card inside the PK-232SC.
The sound card audio is transformer isolated from the USB circuitry. The sound
card/PK-232 switch or a software command selects either sound card transmit audio or
PK-232SC transmit audio. Receive audio from your transceiver is always connected to
both the sound card receive audio and the PK-232 receive audio.
Ports 3 and 4 of the USB hub connect to a dual USB jack on the back panel of the
PK-232SC. Use these jacks for rig control of USB-equipped transceivers and for other
USB station accessories.
A new feature in the PK-232SC is an instant reset switch. A quick flick of the switch
when the power is off resets the PK-232SC to factory default condition.

mode.
The sound card mode (blue LED) is active if it is selected with either the panel
switch or the software control. The software control will override the front
panel switch PK-232 mode selection.

Operation
Note: This manual covers the features added with the SC version of the PK-232.
The main PK-232 manual describes the modes and features found in the
original PK-232 and PK-232MBX. The DSP manual supplement describes
the DSP board features.
PC USB Connection
Connect the PK-232SC to an USB 2.0 compatible port on a computer with a single USB cable (USB miniB
to USB A). No other computer connections are required. The computer USB port must be capable of
supplying full USB power (5.0 Volts @ 500mA.) If a USB hub is used, it must be a powered hub.
USB device driver
The device drivers for Windows XP/VISTA/7 will load automatically when the PK-232SC is connected to
your Windows PC if it is connected to the internet. The drivers are also found on the CD distributed with
the PK-232SC and on the Timewave web site (
and Apple computers. Please contact Timewave or visit the Timewave website for further information.
Note: This device driver is different from previous PK-232/USB device drivers. The older drivers will not
work for the PK-232SC.
www.timewave.com.) Other drivers are available for Linux
Power
Connect the PK-232SC to a +13VDC @ 750 mA. power supply. Press the PK-232SC power switch to the
IN position. This connection is the same for all models of the PK-232.
Radio
Connect your radio data audio input, data audio output and PTT line to the PK-232SC Radio 1 or Radio 2
ports. This connection is the same for all models of the PK-232. If you are upgrading your PK-232MBX
to a PK-232SC, you can use your existing cable if you do not change radios. This connection is the same
for all models of the PK-232.
PK-232SC Ports
The PK-232Sc has two COM ports, a USB Audio sound card port and 2 USB ports.
The PK-232 terminal program uses the “standard” COM port to control the PK-232SC operation.
The PK-232SC rig control program uses the “enhanced” COM port to control your transceiver.
The PK-232SC sound card mode programs use the “USB Audio Codec” to run sound card
programs.
The PK-232SC USB ports appear on your computer USB port list and can be used for USB 2.0
compatible USB devices.
