JUMA COM
HUB
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.
