MBD-12F

Automatic Antenna Switch Controller

MBD-12F is a standalone, intelligent controller, no PC required for configuration. It is compatible with

all twelve-antenna switches manufactured by Hamplus. The MBD-12F managing up to twelve antennas and

six radios, one unit for each radio provide all the interlock necessary for a save operation. It has a band

decoder to receive the information coming from the connected radio equipment. In addition to antenna

switching, the MBD-12F also offers eight frequency-driven GPOs (General Purpose Output), one Band Data

BCD Output, one output to command Band Pass Filter.

The MBD-12F interface, using only the panel antenna keys, has a unique ability to select a dedicated

receiving antenna or to lock the transmit antenna and use temporally receive on any other antenna you have

so you can find the best signal to noise ratio on the station you are working. You can also control dedicated

systems from Top Beam’s Waller Flag receiving antenna.

Antennas with dedicated tuning needs, like 80m Yagi or vertical antennas with tuner can use the GPI / O

for reading and triggering external relay or equipment. The MBD-12F also control up to eight Rotator using

only one indicator on your desk, using the RS-28 and RS-48 Rotator switches.

There are four ways that antennas and enabled rotators can be selected;

1) Manually by the front panel of the MBD-12F,

2) Manually by frequency or band change on the front panel of the transceiver,

3) Automatically by frequency or band change by the remotely controlled transceiver,

4) Automatically by a remotely controlled personal computer via Lan port to the MBD-12F.

GPI/O = General Purpose Input and Output

Functions and operation

1- Connect the MBD-12F to an antenna switch type AS-1202 / AS-1204 / AS-1206 ...

2- Startup

The MBD-12F storage the last antenna used for each band on an EEPROM memory. It does no lose the

information removing power on the unit. The MBD-12F records last antenna selected any time you

change band or turn off the unit. When you turn on the MBD-12F, it read the frequency form the radio

and auto selected the last antenna you used on the last band. The Rotator and GPI/O configuration are

saved in the EEPROM memory too.

3- Choose the antennas

To select an antenna, press one of the twelve push buttons. When the push button is pressed, it grounds

he output pin that activate the corresponding relay on the antenna switch connector. It also activates

the selected rotator for the antenna.

MBD-12F –Operation Manual Page 2

The Busy Net LED informs the antenna and the corresponding rotator programed for that antenna push

button, and send the information to the others MBD-12F connected on the busy-net, so the antenna

selected is in use, and cannot be selected by others unit. It does not allow another MBD-12F to select an

antenna or rotator already in use. If you try to select an antenna in use the busy-net LED will flash for

few seconds and the antenna won’t be selected when you release the push button. When there is

conflict the signaling flashes with cadence of 0.5 seconds as long as you try to select a used antenna or

used rotator.

4- SPLIT Mode

This mode allows operation with two antennas. One for transmission and one for reception. It temporally

locks the transmit antenna and you can choose any other antenna to receive. This function allows you

quickly to select the best antenna to receive and keep transiting on the antenna you locked.

Procedure to enter “SPLIT” mode:

a- First, select the transmission antenna #_x. The push button key will light and the busy-net LED

will light on the other units indicting that the antenna #_x is in use.

b- Then press the PTT of the radio and holding it down, and press the push button of the desired

antenna for reception until all the push buttons LED stat flashing.

c- When you release the PTT, the “Split” LED will light and the unit is now in “SPLIT” mode.

d- Now you can select any other antenna to receive, but only transmit on the locked antenna. To

change the receiving antenna simply press the push button of another antenna.

e- Because you are using two antennas, one for RX and another for TX, two busy-net LED will light

on the other units indicating that both antennas cannot be selected

Check the split function by pressing and releasing the PTT of the radio and observing the push button of

the MBD-12F that must switch between the chosen antennas.

To exit the SPLIT mode:

You have two options

1- Switch band on the radio.

2- Press the antenna button set to transmit, all the push button LED’s will flash indicating that

you are releasing the Split mode.

5- EXCLUSIVE Antennas for RECEPTION (Permanent Split Mode)

The MBD-12F can configure receive-only antennas. It means you cannot transmit or select that antenna

on that unit, if you are using several MBD-12F you need to configure the same antenna as receive only on

all units. Whenever you select an antenna configured as EXCLUSIVE for RECEIVE, the MBD-12F will

automatically activate the SPLIT mode and when leaving this antenna, the MBD-12F will disable the SPLIT

mode.

Procedure for setting up an antenna for EXCLUSIVE Reception:

Do the same on all other MBD-12F connected to your antenna switch.

a- Select the transmit antenna and press the PTT, and hold it, then press for ten seconds or more

the button of the antenna you chose for EXCLUSIVE reception until all the buttons LED’s will

flash for few times.

b- The Split LED will light on indicating that you enter in split mode.

c- Keep holding for 10 or more seconds until all the push buttons LED flash again.

d- Then the Split LED will turn off, indicating that the selected antenna for reception is now

EXCLISIVE for reception on this MBD-12F unit.

MBD-12F –Operation Manual Page 3

Checking the operation

Press on the MBD-12Fthe EXCLUSIVE Reception antenna button and see that the SPLIT LED

indicator will light. Press the PTT of the radio and note that the MBD-12Fswitches from the

EXCLUSIVE Receiving antenna to the antenna you selected before to transmit.

The advantage off EXCLUSIVE receive antenna is that you do not need to configure the Split mode all

the time. Let us say you have a beverage antenna receiving only antenna. The MBD-12F will not let

you transmit on the EXCLUSIVE receive antenna. Select the transmit antenna and after that select

the exclusive receiver antenna, the Split LED will light on. When you push the PTT the transmit

antenna will be selected.

Selecting any other antenna, the Split LED will turn off. Selecting again the EXCLUSIVE receive

antenna the SPLIT LED will turn on, and two busy-net LED will light on the others MBD-12F.

With the EXCLUSIVE receive mode, the configuring will not change when you change band or select

another antenna. It is permanent until you re-configure the receiving only antenna.

To remove an antenna from EXCLUSIVE Reception mode

a- First, select on the MBD-12Fany antenna not in receiving mode, the SPLIT LED should be not be

light.

b- Press the PTT, and hold it, then press for ten seconds or more the button of the antenna you

want to exit the EXCLUSIVE reception mode. All the buttons LED’s will flash for few times.

c- The Split LED will light, indicating that you enter the split mode.

d- Keep holding for 10 or more seconds until all the push buttons LED flash again.

e- Then the Split LED will turn off, indicating that exit the EXCLISIVE mode.

f- Push the PTT now and check that now you transmit and receive on the same antenna. The busy-

net LED will indicate that only one antenna is in use on this unit.

OBS: if you are configuring antenna push button #1, you may hold it long enough to enter the

MBD-12F in configuration mode. The LED’s # 1 to # 8 will flash in sequence indicating the unit is

waiting to select the mode.

Press the # 12 button to exit the configuration mode.

6- GPOs2 Activation

The GPOs2 are eight pins available on the DB-9 connector labeled GPO2 located on the back of the

MBD-12F. These GPOs2 are used to tune shortened antennas with high Q coils.

GPOs2 can be triggered in two ways. By frequency and or by band. Each GPO2 is individually configured

and is associated with one of the 12 antenna positions. This means that the eight GPOs2 can be configured

to a single antenna position or one can be configured for each of the twelve antenna positions.

To configure the GPOs2 see item 12 B

7- Antenna groups

On MBD-12F you can create groups of antennas. When a radio accesses one of the antennas in this

group, all the antennas in this group inform Busy Net that they are busy. This means that no other radio

has access to an antenna belonging to this group. Only the radio that is connected to one of the

antennas in this group is allowed to use the other antennas in this group.

Example for a contest.

Create a group with the antennas for the 10m band. Only the radio operating in the 10m band will have

access to the 10m band antennas. The other radios will not have access to any of the grouped antennas.

You can create several groups of antennas.

To configure a group of antennas, see item 12C

MBD-12F –Operation Manual Page 4

8- Switching Rotors

The MBD-12F also commands the RS-24, RS-44, RS-28 and RS-48 rotor switches. In this way a single rotor

control can control up to 8 rotors.

To configure the rotor switch, see item 12A

9- Communication with Icom, Yaesu, Kenwood, Elecraft K-3 and Flex Radio

a. ICOM - CI-V protocol (CI-V port) for reading the frequency for the activation of the selected

Antennas, Rotors and GPIs.

b. YAESU- BCD protocol for reading the band for the activation of the selected antennas and GPIs.

c. Kenwood- RS-232 protocol for frequency reading for the activation of Antennas and GPIs. K3

and Kenwood use the same RS-232 protocol.

d. Elecraft K3- protocol BCD and RS-232.

e. Flex Radio, K3 and Kenwood use the same RS-232 protocol.
