Linker - Selections and Connections
DC POWER INPUT
allows either an external DC power supply to be
plugged in or a 12 volt battery to be connected.
The DC power socket mates to a standard 2.0mm ID DC power plug.
CVP’s DCPS120 power supply plugs directly into the socket. The variable
DC output should be set to about 18 volts for best operation of LGB snap
action turnot motors. If using solenoids or relays, set the DCPS120 output
voltage to the voltage rating of the solenoid or relay.
If using a battery, proper polarity must be observed. Reversing the polarity
will not damage the Linker but it also will not work.
The Linker
does not automatically turn off after a period of no use. Be sure
to disconnect the battery if not used.
Do not use both inputs at the same time.

Normal Setting
Output pairs AorB
connect to the remote Activators. Use one or both at the same
time.
The pluggable header accepts wire sizes ranging from 12AWG to 26AWG. If
using stranded wire, it must be twisted and tinned. Cut the stripped and tinned wire
so that it is completely inside the clamp area and keep the insulated portion outside
the clamp for a good connection.
To remove the plug from the socket, gently rock the plug back and forth
horizontally to release the locking tabs.
Replacement plugs are available from CVPProducts.
Heavy Duty Wiring is Required
Inadequate wiring will not allow the short circuit sensor
to work correctly and can pose a safety hazard. There is
almost no limit to the length of wire between the Linker
and the Activators. However, if going very long
distances, consider the use of #12AWG or #14AWG
wire.
PW-OK LED
turns on when power is
applied.
DCC-GP LED
turns on whenever valid
throttle signals are detected. This light may
flash on and off which is normal. This
indicates some frequencies are not in use.
FLT-ER LED
turns on any time there is a
short circuit or overload on the output wires.
In normal operation, this LED is off. During a
short circuit the alarm buzzer will also sound.
When the short or overload is corrected, the
buzzer and LED will turn off.
SCAN RATE
potentiometer (pot) sets the rate at which
the Linker scans each of the 8 frequencies. With the pot
rotated to the LO setting, there is a better chance of
receiving throttles that are a long distance from the
receiver. However, there is a better chance of missing
activation commands especially when many
frequencies are active.
With the pot set to HI, activation commands are almost
instantly received and acted upon. However, distant
throttles might not be received.
For most applications, place the pot in the middle of its
rotation range. This provides a good balance between
remote reception and fast activation.

Antenna
The threaded aluminum rod is the
Linker’s antenna. It is shipped
unattached for protection.
Gently screw in the antenna through the
hole in the top of the case. The antenna
should be finger tight for best
performance – don't over tighten.
Do not obstruct, cover, or otherwise
allow anything to touch the antenna.
Do not carry or pull on the Linker by its
antenna.
Always touch a metal object before
touching the antenna to discharge any
accumulated static electricity.

Your Throttle May Need ASoftware Upgrade
Check your T9000 throttle software revision number. It must show revision
1.3 or higher. If not, it will need to be returned to CVP Products for a free software upgrade. You pay the shipping charges to
return the throttle to CVP. CVPwill pay for the return shipping.
For the RF1300 throttle, check that the label on top of the chip says GTX-8A. If not, or if you are not sure, call us for a free chip
to upgrade to the latest software. Instructions and the new chip will be sent at no charge.
Placement Suggestions:
Higher is usually better for maximum range. To
keep wiring to a minimum, consider locating the Linker near a cluster of
Activators. Multiple linkers may be used without interfering with each
other.
Several Linkers may share a
DCPS120 power supply.
