JUMA COM Hub Interface

JUMA COM Hub Interface

JUMA COM HUB provides a connection between your PC/Mac software, transceiver and JUMA PA1000. It will share the single serial COM port of your transceiver. PC/Mac and transceiver are seamlessly connected together while JUMA PA1000 is tracking the band by polling the transceiver frequency. JUMA COM HUB is powered by PC USB cable and you don’t need a USB – RS232 converter because that is built in to JUMA COM HUB. We are using FTDI USB chipset which is compatible with Windows. The USB COM driver will be installed automatically when you plug in COM HUB to your PC. The green LED will be lit when the driver has been successfully installed and the USB port is ready to use.

JUMA COM HUB supports Kenwood, Elecraft and Juma compatible transceiver CAT protocols. Additionally you can select a transceiver independent time out based mode** for other similar applications. The available baud rates are 9600, 19200, 38400, 57600 and 115200. The enclosure is small 65 x 65 x 30mm and the weight is only 0.07kg. The interface is supplied from 5Vdc (PC USB).

You will need cables for the interface, accordingly to the description below. Specific cables are needed from transceiver interface etc.

See complete SET-UP instructions below at “Description”.
