General

• Use this relay board to switch antennas or other ancillary equipment.
• The USB 8 Relay Board may be driven using one of the following methods.
  • Using the band boxes in the USB 8 Relay Board group on the Features tab.
  • Using the Band Data File on the LPT tab.
  • Using the DDRB macro command.

GUI Controls

• Enable → Select to enable the Denkovi USB 8 Relay Board

Note: There is now a 2nd source for the Denkovi board at a cheaper price called a SainSmart 8. This board is from China and is a drop-in replacement for the Denkovi board.

• Use Band Data File → Selecting this check box will disable the local auto band following defined in this Graphic User Interface and enable using the Band Data file on the LPT tab.

Note: → See the Band Data File section below for more information.

• Band Boxes → Enter a decimal number for each band you want the board to activate a relay for. Entering the following numbers produces:

1 = Relay 1 activated

2 = Relay 2 activated

3 = Relays 1 & 2 activated

7 = Relays 1, 2 & 3 activated

255 = All relays activated

Notes:

1. Relays are activated in Binary notation (00000111) = 7.
2. See the Macro command DDRB for additional programming information for this board.
3. To use the relay board to band switch an amplifier that uses Yaesu binary notation use the following setup:

  160 = 1   80 = 2   40 = 3   30 = 4   20 = 5
   17 = 6   15 = 7   12 = 8   10 = 9    6 = 10

Band Data File

• Optionally the Band Data File on the LPT tab can be used to drive the USB-8 Relay Board for enhanced operation vs. the band only operation of the USB 8 Relay Board group settings on the Features tab.
• To use the Band Data File option follow these steps.
  1. Make sure a properly edited Band Data File is showing on the LPT tab.

     Note: → See this link for more information on setting up the Band Data File.

  2. On the Ports tab take the following actions.
     1. Select the Enable check box in the Parallel Port group.
     2. If not using a parallel port also, select None as the port number.
  3. On the Features tab in the USB 8 Relay Board group select the Use Data File check box.
