Figure 9. Pelco Time-Lapse VCR Wiring Example
To connect one of Pelco’s Time-Lapse VCR Models TLR2024, TLR3024, TLR3040,
TLR2096, TLR2168, or TLR2168S to the multiplexer (refer to Figure 9):
1. Connect BNC video cable between the VCR connectors on the multiplexer and the
VIDEO connectors on the VCR.
2. Head (or VCR) Switching Pulse lets the VCR control the multiplexer’s recording speed.
It is the most efficient recording method. To wire (refer to the “B” lines in Figure 9):
a. Connect the VCR’s CLK output to the multiplexer head switching (H) input to
synchronize camera switching.
b. Connect the multiplexer’s ground terminal to the VCR’s GND terminal.
3. Alarm recording starts and stops when there are alarms. To wire (refer to the “A” lines
in Figure 10):
a. Connect the multiplexer’s TTL output relay (O) terminal to the VCR’s SET IN
(alarm input) or ALM IN terminal.
b. Connect the multiplexer’s ground terminal to the VCR’s GND terminal.
NOTE:
The TTL output re-
lay (O) terminal is designed
to be used with devices un-
der 5 mA.
