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.

If both blue and amber LEDs are on at the same time, you have selected the SC mode with software control and have set the panel switch to PK-232 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.

Maximum 100 mA. each unless 5VDC power supply is connected. 21) +5VDC ONLY! Do not connect any other voltage to this jack! Center of jack is positive polarity. 5 Volts DC only @ 2A for powered USB hub operation only Required only for USB devices that draw greater than 100 mA. To use this jack, you must change a jumper inside the PK-232SC.
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.
Some programs will automatically identify the correct ports for their functions. Others may have limited ability to aid you in connecting the correct port to your software application. If you wish to identify or edit the various PK-232SC ports, use the Device Manager application found in Windows XP/VISTA/Win7. Go to Control Panel/System or Computer/properties to find Device Manager.
SC Board Jumper Settings The SC board has several jumper options that may be changed by the user. In most instances the jumpers can be left at the factory default settings. The jumpers are located on the SC daughter board at the rear of the PK-SC. Rig Control Not all transceivers have the same polarity settings for their logic level rig control ports. The PK-232SC polarity settings for RX, TX, RTS and CTS can be changed to meet the requirements of any specific transceiver.
