IBS-1 Automatic Band Decoder






The IBS-1 Intelligent Band Switch is designed to provide flexible,
intelligent automatic control of antennas in one and two transceiver environments. The unit runs
off of 12 volts and interfaces directly to Yaesu and Icom transceivers. It also interfaces to the
band-data outputs generated by many logging and contest programs for Kenwood radios, which
have no band data output jack.

The unit has 10 antenna outputs that can be configured in a number of different ways. The
outputs from the IBS-1 Controller are 12 volt DC and source up to 300 milliamps. Optional relay
boards are available for applications that require sinking or different voltages. The relay
boards are available in Single Radio format and in a Dual Radio Format. The Controller measures
6"w by 3"h by 2"d (15x8x5.5cm) and fits nicely on top of the transceiver.

The unit is powered by 12 volts DC and allows automatic or manual selection of a number of
antennas. In addition to nine auto/manual antenna outputs, there is a "Special" output that can
be used for a dummy load or a reference antenna.



Installation of the IBS-1 is straightforward. If you are installing the IBS-1 without
the Relay driver option, refer to the next section.

Here are the basic installation steps:


1. Open the Controller Unit and configure the jumpers as you require for your installation. The
factory setting is one relay per band (1-9 = 160 through 10).
2. Connect the external antenna wiring to the appropriate terminals on the antenna switch for
each
radio. Note that Relay Circuit #10 is for a "special" antenna, e.g., a dummy load. You can select
this output at any time by pressing the "SPECIAL" button on the front panel of the controller unit.
3 .If the IBS-1 is to be used with an FT-1000x, plug in the provided connector from the
appropriate controller to the "Band Data" jack on the FT-1000x. No other settings are required for
Yaesu FT-1000x use.
4 .If the IBS-1 is to be used with Icom, use a 1/8" single circuit jumper cable to plug in to the CIV
output (Remote or one of the available jacks on the CIV interface module, if you have an older CI-
V interface you can buy a Y adapter cable from Radio Shack for this purpose.) Configure the
Baud Rate on the ICOM for either 1200 or 9600. The IBS-1 is jumpered from the factory for 9600
baud. These are the only two baud rates available.
5. Apply power to the system.



Installation IBS-1 Directly to Antenna Relay Box or through the Relay Driver
Option box.

Installation of the IBS-1 is straightforward. There are ten outputs that source 12
volts DC to ground.
There is a 12 conductor cable that is used to interface to the antenna relay unit
(such as the Array Solutions SixPak). Configuration jumpers are provided that
control which leads are activated on various bands.
Each output is able to source up to 300 milliamps and is protected against short
circuit conditions.
Important note: the IBS-1 requires that at least 100 milliamps be drawn from the
active output. Also, we STRONGLY discourage using the IBS-1 outputs to drive
cables outside the operating area. If the antenna switch is located outside the
operating area, the "
Level Converter and Relay Driver Option
" should be used
from Array Solutions. It will re-drive from up two IBS-1s (or 12 signals) to a
SixPak or remote antenna switches. It also provides a great little junction box to
integrate your cables for bandpass filters as well as the SixPak to help make the
cable terminations easy.

For dual radio installations (SO2R), you must assure that the relays are
"interlocked" so that you cannot select the same band for both radios. The Array
Solutions Relay Driver Option Box does this very well when couples with the
WX0B SixPak. If you use bandpass filters in addition to the antenna selectors the
best solution for this is to use the Relay Driver Option Box. Wire the outputs of
the IBS-1 to the input terminals of the Relay Driver Option box, this will allow the
IBS-1 to sense the current being drawn by the bandpass filter relays ( the Array
Solutions FM-6 product). Then wire the SixPak or antenna switches to the output Array Solutions

of the Relay Driver Option. You can drive a considerable distance with this by
upping the +V DC supplied to this box say to 16V DC if you like.

Here are the installation steps:

1.The 12VDC power is connected to the Black wire (ground) and Pink wire (12VDC).


2.The outputs 12 volt sourcing. If 12 volt sinking is required (ground common) then you must
use the Relay Option Board configured to be a Level Converter, or provide relays of your own.
Connect the wires to the input terminal strip of the Relay Driver/level converter box.


3.Open the Controller Unit and configure the jumpers as you require for your installation. The
factory setting is one relay per band (1-9 = 160 through 10). (NOTE-This is the most likely setting
for contesters even if you use a tri-band antenna, so that you can chose the proper bandpass
filter. Use steering diodes to select the tri-bander. This is easy and we have a diagram for you if
needed on how to do this.)


4.Connect the output drive antenna wiring to the appropriate terminals on the Relay Driver input
terminals.
Note that Output #10 is for a "special" antenna, e.g., a dummy load. You can select this
output at any time by pressing the "SPECIAL" button on the front panel of the controller unit.

4.a If bandpass filters are used connect 12V sourcing filters to the input terminals of the Relay
Driver Box. The IBS-1needs to see 100ma being drawn from it. The Array Solutions FM-6 matrix
for filters satisfies this requirement. If you use a Sinking band pass filters such as the ICE 419A
units you must configure the system with a Level converter Box to drive sinking current to the
419As. Place the Antenna Relay on the input terminals (12V source) and the 419As on the output
of the Level Converter box. You can call us for detailed information on this if needed. Basically we
have the parts to configure the IBS-1 to take care of all the commonly configurations of
commercial antenna switching and bandpass filtering.

5. See comments above for connecting to the radios band data jacks.

6. Outputs from the Relay Driver Option Box, if used, should go to the appropriate antenna
terminals of the antenna switch. Other wise connect the IBS-1 outputs directly to the antenna
switch if inside the shack.


7.Apply power to the system. See the section below for operational details.

Operation

The IBS-1 is simple to use. It automatically senses the band you have chosen
and drives the relays as instructed by the jumper settings inside the unit. If you
try to select a band that is already in use by the other radio, the IBS-1 indicates
"Er" (in some configurations) and waits for you to select another antenna. If you
move the second radio off the conflicting band, the IBS-1 automatically corrects
the problem and reselects the originally selected antenna.

ICOM notes: for ICOM, the IBS-1 is able to sense ALL bands, including 30
meters, 17/15/12/10 and six meters. It does this by monitoring the CIV
communication. There are a few things to keep in mind for ICOM:


1. When first powered on, you must cause the ICOM to output its band data. Do
this by twisting the tuning knob or by changing bands. Until you do this, it will
sit on 160M.

2. When using remote control software, a band change may or may not trip the
IBS-1. Again, a slight tweak of the tuning knob will update the outputs. CT is
known to require this operation.

3. Be sure your baud rate is set correctly. The IBS-1 will not work unless it is.


User Interface

The IBS-1 has five 7-segment displays. The first three of these indicate the
selected band. The right of pair of these displays indicate the selected antenna.
When in automatic operation, the antenna number (1-9) is indicated with the
letter A followed by the antenna number. The "A" is not there when manual
operation is selected via the front panel switch.

For manual operation, flip the front panel switch to manual. You can then
manually select the antenna you want by pressing the "SELECT" button. It cycles
from 1 though 9.

The IBS-1 supports a "SPECIAL" position. When you press the "SPECIAL"
button, antenna relay #10 is selected. This can be used for a dummy load (most
common application). It can also be used to select a special antenna of some
