Using Your AutoHybrid
Auto-Answer
When the
is in the in position, AutoHybrid will
answer on the first ring. AutoHybrid
will look for a CPC disconnect signal
from the phone company to determine
when a call has disconnected. This will
generally take only several seconds
but can take up to a minute. If you
are using a simulated analog phone
line provided by a PBX system, the
system must be configured to send a
disconnect signal for the AutoHybrid's
auto-disconnect function to operate.
The CPC disconnect signal must be
set at 300 ms minimum.
Remote Screw Terminal
1 2 3 4
Call Drop OH LED Ground
The detachable remote control screw
terminal block on the back of the
AutoHybrid provides connection to
switch contacts for remote operation.
A momentary +5 VDC applied to Pin 1
takes the phone line off-hook. Another
momentary +5 VDC applied to Pin 2
will drop the call.
Pin 3 is an open collector opto-isolator
terminal that is pulled to ground while
AutoHybrid is off-hook. This terminal
is protected by a 220 ohm series
resistor. You can light a remote LED
by simply connecting your LED from
+5 VDC to pin 3.
