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 by routing the serial communication. JUMA COM HUB is powered via USB port 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 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**. Available baud rates are 9600, 19200, 38400, 57600 and 115200 (Note. Baud rate will be set only during power-up). The enclosure is small 65 x 65 x 30mm and the weight is only 0.1kg.

** Time out based mode is forwarding data packets after a 50ms pause in the data stream.

It is very easy to use
1. Select the baud rate with a jumper. Set the same baud rate to PC, TRCVR and PA1000 COM1. (No hand shaking)
2. Select the mode with the CONFIG jumper.
3. Connect a type B plug USB cable between PC and COM HUB and wait for automatic USB driver installation. Watch the green LED.
4. Connect a serial cable between transceiver and COM HUB. This is a cable illustrated in JUMA PA1000 user manual for your transceiver.
5. Connect a standard 3.5mm stereo audio cable between JUMA PA1000 and COM HUB.
