4. The LTC 2600 Series multiplexers are configured to record and playback from a wide range of VCRs.The VCR
provides a pulse (VEXT) each time a video field is recorded to tape.This signal lets the multiplexer know that it
can switch to a new camera.This feature also simplifies installation by synchronizing the normal and alarm
recording speeds.You will need to decide how you are going to synchronize the multiplexer and the VCR.
Either accomplish the following steps for synchronization using the VEXT input (recommended), or perform the
alternate method (programming the VCR model and corresponding time-lapse speed).
NOTE: VCR SETUP is an involved programming sequence with many options. Please read through the
information in this section carefully to understand all the options available.
Synchronizing the VCR using the VEXT Signal
If provided by the VCR, use of a VEXT signal is the preferred method of synchronizing the Multiplexer and the VCR.
The VEXT pulse is a signal provided by the VCR that causes the Multiplexer to sequence to the next camera. It is
highly recommended to use this method if supported by the VCR as it will ensure optimal update rate and
performance of the Multiplexer. Select VCR SETUP (menu shown below).
• Connect and enable the VEXT output from the VCR, then choose the recording speed of the VCR.
• Connect the VEXT output from the VCR (CAM SW Out or Record Out) to Pin 21 and Ground to Pin 25 of
the Alarm In/Out.
• From the VCR SETUP menu, select the RECORD SETUP option.
• From the RECORD SETUP menu, select VEXT INPUT. Switch it to the ON setting (the factory default is
OFF). Using this feature will bypass the time-lapse setting in the multiplexer VCR selection menu (i.e.
programming SELECT VCR and TIMELAPSE are not required.)
