1.2 BD1/BD2 Ports: Radio Band Data connection
You can use the Band Data input with a Yaesu or Elecraft K3 transceiver; also ICOM
Band Voltage input is supported. RemoteBox will receive Band Data and will allow for
automation of antenna selection based on band information. This adds practicality
and error proofs the radio shack.
This is the Pin Out of the Band Data port:
•
Pin-1: Common Ground
•
Pin-2: Band Data A
•
Pin-3
Band Data B
•
Pin-4
Band Data C
•
Pin-5
Band Data D
•
Pin-6: Inhibit (see *Note 1)
•
Pin-7: PTT In (see *Note 1)
•
Pin-8: Not used
•
Pin-9: Band Voltage Input (ICOM)
Note 1: Those options are available adding an additional module.
You can also use any device that reads CAT information and translates it into
standard Yaesu/Elecraft type Band Data.
Important Note: Firmware versions before April 2016 don’t support the Inhibit and
PTT IN control signals
The RemoteBox can read which is the band active for each radio and with the
INHIBIT option enabled (SET 4), if it detects that both radios are at the same band, it
will inhibit both radios to transmit.
The “PTT In” will allow to control if the Radio is transmitting so it can be used to avoid
a hot-switching. So in case you want to avoid to change the antenna relays
meanwhile the radio is in TX mode, you must connect the PTT from the radio to pin 6
and enabled the PTT for that Radio (SET 5)
You have to activate the Band Data options (SET1 and/or SET2) as well as configure
the RBM band data/antenna matrix prior to using this functionality.
The Band Voltage input (ICOM) provides the same level for 17m/15m. In a
similar way the ICOM supplies the same voltage for 12m/10m so the RemoteBox
cannot detect the difference between 17-15m or 12-10m
