BM-5 BandMaster V Installation


Before you begin


    Installing and configuring the BM-5 BandMaster V is a simple process. All configuration is done from the front panel. Installation and configuration steps are listed below.



Power / ShackLAN connections


   The first step in the installation of the BM-5 is to connect 12vdc power to the unit. This can be done using either the power jack or via either ShackLAN jack from another device on the network.   More information for the network and power connections are here. 



USB Connector


   The USB connector is used to transfer data to and from the radio to your computer using a standard USB cable. It is also used to update the firmware. The USB may also be connected directly to Flex SDR radios. The USB driver should automatically install itself. If it does not, drivers can be downloaded here.


CI-V Connector


   This connector is used to interface to Icom radios. It uses the standard 1/8" phone plug used on all Icom radios for computer control. It should be connected to the REMOTE jack on Icom radios. For other makes of radios a CI-V data stream is sent from this connector to allow control of external devices.


Radio Connector


  This connector is used to interface to all radios except Icom. You can use the same cable you would normally connect between the radio and a computer except when using the band data outputs from Yaesu and K3 radios. It is preferred that you use the RS-232 data from the radio and not the band data outputs otherwise there will be reduced functionality. If you still wish to use the band data outputs, you will need to make your own interface cable or purchase a custom cable. Band data signals are labeled A, B, C, D in most radio manuals but may be designated as 1, 2, 3, 4 or 1, 2, 4, 8. Pinouts for the radio connector are shown in the diagram to the right. Consult your radio manual for pinouts on the radio connector. When acquiring radio data from the CI-V, USB or band data this connector will transmit a RS-232 data stream in either Kenwood or Yaesu format. When not using band data from the radio this connector will output band data information.

Relay common selection



   The BM-5 has 12 internal relays with the relay common available at the rear panel. This common connection may be used to enable the relays to switch to +12vdc, ground or an external voltage. These selections are made using jumper pins inside the unit. The jumper is located behind the relay connectors. The factory default is to provide 12vdc when the relays are activated and should cover most installations. To change the common selection, remove the 4 screws from the rear panel and slide the board out far enough to access the jumpers. Shown to the right are 4 selection options. 


Supplies 12vdc when activated. "C" pin is ground.

(Factory default selection)


Supplies 12vdc when activated. "C" pin is not connected



Switches to ground when activated. "C" pin is not connected



Connects to the power source on the "C" pin




Relay Connections


Relay connections are made via the pluggable 7-pin connectors. No soldering is required. Each connector has outputs for 6 relays. The relay outputs are labeled 1 thru 12. The G pin is ground and the C pin is for an external voltage, if desired.  Attach the control wires by inserting them into the holes in the connector plug and tightening the screw to secure them.
