General

Use this relay board to switch antennas or other ancillary equipment.

GUI Controls

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. See the Band Data File section below.
  • 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
