USAGE
KEYLINK is a versatile eight channel dig-
ital IN/OUT unit which can be used as
a handheld keypad transferring key clo-
sures from its built-in keys to the Dataton
control system. Alternatively, external
switches may be used, connected in par-
allel with the internal keys. Such switch-
es are connected via the 10-pole screw
terminal, where two poles are reserved
for the common connections (ground)
and the remaining eight (labeled
1–8) for the corresponding keys.
The screw terminal channels also double
as digital outputs. When “ON”, these
outputs make a low impedance connec-
tion with the common poles. When
“OFF”, they are pulled to an internal
12V DC source via 1.5 K
Ω
resistors.
The screw terminal poles may be turned
to “ON” as a result of key pressure on
the KEYLINK unit itself or as a result of a
programmed action from Dataton TRAX.
In both cases, the corresponding key’s
LED is lit.
KEYLINK is used with
the SMARTPAX QC
control unit in the
Dataton system. To
connect KEYLINK to
a SMARTPAX QC,
use the enclosed
cable, 3443 SMARTBRANCH FIRST
CABLE. The snaplock connector plugs
into a SMARTPAX QC port and the mod-
ular connector goes to the IN port on the
KEYLINK. To identify the KEYLINK unit’s
IN port, look for the single green diode
at the base of the unit. The IN port is the
one placed closest to this green LED.
CONNECT MORE UNITS
To connect additional units on the same
SMARTPAX port, use the enclosed modu-
lar to modular cable, 3444 SMART-
BRANCH LINK CABLE. This should go
from the OUT port of the first KEYLINK to
the IN connector on the second unit. In
this way, you can run up to four
KEYLINK units from one SMARTPAX port.
You may mix POWERLINK and KEYLINK
units on the same SMARTPAX port. The
remaining ports may be used to control
more POWERLINK or KEYLINK units, or
unrelated media devices as required.
