Operation
Your DTS-6/6R has no power switch; it powers up when you plug it in. The relay associated with
the selected antenna is energized and draws current all the time.
Operation is exactly the same whether you use the DTS-6 directly, or remotely with the DTS-6R
remote control.
Selecting an antenna
Never attempt to change antennas while transmitting. If you attempt to do so, the DTS-6 will
not
switch, and all six LEDs will flash to indicate the error condition. To change antennas, stop
transmitting and press the button on the DTS-6 or DTS-6R corresponding to the desired antenna.
You will hear a distinct "click" as the relays change state. You can change antennas as often as
needed; just be sure to stop transmitting before you press a button.
Grounding all inputs
To ground all inputs, stop transmitting, then press buttons 5 and 6 together. All ports are
grounded; lights 5 and 6 will flash twice to confirm grounding. Never attempt to transmit when
the DTS-6 inputs are grounded; your transceiver or transmitter may be damaged. When all inputs
are grounded, all four LEDs are out. To unground, simply press the button for the desired
antenna. The LED for the selected antenna will light, indicating that it is ungrounded.
Setting Radio Sense mode On and Off
To set Radio Sense mode on, press buttons 1 and 2 together. All six lights will blink twice to
confirm that Radio Sense mode is on. Whenever your rig is off (that is, the DC power port on the
radio is off), the DTS-6R will automatically ground all inputs. If you press an antenna selection
button while the DTS-6R is grounded in Radio Sense mode, lights 1 and 2 will blink three times
to remind you; the antenna will
not
be selected.
To set Radio Sense mode off, press buttons 3 and 4 together. Lights 3 and 4 will blink twice to
confirm that Radio Sense mode is off. The last antenna you were using will be automatically
selected.
Application Notes
Your DTS-6 is perfectly suited to mobile use. Simply install it in a convenient location near your
operating position, and provide 12 volts DC through a fused line (fuse not included; LDG
recommends a 1 amp fast-blow fuse). Or, you can install the DTS-6 in the trunk near your mobile
antennas, and use the DTS-6R near the operation position. The DTS-6R also requires a fused
power line.
Many modern transceivers have a "auto off" function, allowing you to program the rig to turn
itself off at a specified time. Using this function along with the Radio Sense function of your
DTS-6 insures that the rig will be protected even if you forget to turn it off. At the programmed
time (midnight, for example) the rig will switch itself off. With Radio Sense mode enabled, the
DTS-6 will then automatically ground all inputs, protecting the rig.
