Basic Connections
The Basic Connection Diagram shown above, is the proper way the BDA should be connected
and once up and running, require minimal to none manual configuration. Connections between
cabinets are made through N-Bulkhead connectors located on the top of each cabinet. All
programming and adjusting is done through the software and this manual primarily deals with
this topic.
The computer running the software is connected via an RS232 serial cable to the front panel
connector on each channel.

MAIN SCREEN
Below is the main working screen used to configure the channel card settings.
The primary fields addressed are:
• Communication Connection
• Time Out Timer
• Mode Setting
• Key On Delay
• Key Off Delay
• Attenuation
• Setting a Frequency

COMMUNICATION CONNECTION
This software automatically checks the condition of its communication with the intended
channel. Each message is acknowledged and displayed in the message box at the bottom of the
screen. If the software does not receive a response from the channel, a warning message is
displayed, “NO RESPONSE FROM UNIT”.

TIME OUT DURATION
The time-out duration is how long a channel can be held open (keyed on) for a retransmission.
An inadvertent or intentional “key and hold” action without any voice communication will not
disable the channel because of this feature. The time-out duration can be up set from 1 second to
99 seconds 1 second intervals. The time-out duration can be disabled by setting it to 00, when
disabled, the channel will key continuously with the presence of a received signal.
SETTING A TIME-OUT TIME
To set a time-out time, click on the text box “Time Out Timer” and enter the desired time-out
time up to 99 seconds then click “Send Button” next to the box. To verify the setting, click on
the “Read Button” and the display will be updated with the channel setting.
MODE SETTING
The channel mode may be set to either INHIBIT, CONTINUOUS, CARRIER DETECT or
optional TONE DETECT. In the Inhibit mode, the channel is off and will not key on. In the
50289-BAM-8-800 - 7 -
continuous mode, CW, the channel is always keyed and continuously transmitting. In the carrier
detect mode, CD, the channel is keyed only when the incoming signal strength is above the
factory set threshold level. Normal operation will be in CD mode; continuous mode is normally
used for testing.
CHANGING THE MODE
To change the Mode, click the desired function box on Mode Selection on the main screen. Then
click “Send Button” next to the box. To verify the setting, click on the “Read Button” and the
display will be updated with the mode setting.
KEY ON DELAY
The key on delay is a delay duration between the detection of carrier detect and the transmitter
key on. The key on delay duration can be up set from 0 to 99 milliseconds 1 millisecond
intervals.

SETTING KEY ON DELAY
To set a time-out time, click on the text box “Key On Delay” and enter the desired delay up to 99
milliseconds then click “Send Button” next to the box. To verify the setting, click on the “Read
Button” and the display will be updated with the channel setting.
KEY OFF DELAY
The key off delay is a delay duration between the release of carrier detect and the transmitter key
off. The key off delay duration can be up set from 0 to 99 milliseconds 1 millisecond intervals.
SETTING KEY OFF DELAY
50289-BAM-8-800 - 9 -
To set a time-out time, click on the text box “Key Off Delay” and enter the desired delay up to
99 milliseconds then click “Send Button” next to the box. To verify the setting, click on the
“Read Button” and the display will be updated with the channel setting.
ATTENUATION
With high RF receive levels, an input attenuator can be set 0 to 15dB in 1dB steps.
SETTING ATTENUATION
To set Attenuation: click the function window Attenuation on the main screen. Click on the
scroll bar next to the text box, a scroll down list of available attenuation settings. Double Click
the on desired setting.

SETTING A FREQUENCY
The 8 Channel BDA is shipped with 8 Uplink frequencies and 8 Downlink frequencies. The
user can program any card to any of these 8 specified frequencies.
To set frequency click the function window Frequency Setting on the main screen. Click on the
scroll bar next to the text box, a scroll down list of available frequency settings. Double Click
the on desired setting.

FCC COMPLIANCE AND RF EXPOSURE INFORMATION
This product is certified by the FCC as compliant with CFR.47 Part 90. Any changes
or modifications not expressly approved by the manufacturer could void the user’s
authority to operate the equipment.
To comply with FCC RF exposure requirements, antennas that are mounted externally
at remote locations operating near users at stand-alone desktop or similar
configurations must operate with a minimum separation distance, determined at the
time of site licensing, from all persons.
50289-BAM-8-800 - 12 -
For Downlink operation, the minimum safe distance from the antenna is 20cm with a
maximum antenna gain of 0.6 dBi. This specification is for operation in an
uncontrolled environment.
For Uplink operation, the minimum safe distance from the antenna is 40cm with a
maximum antenna gain of 11 dBi. This specification is for operation in a controlled
environment.
