Overview
The Toshiba JK-MX16A Color Multiplexer has the capacity to support up to 16 cameras and can display
them in a variety of display modes (example: 2 x 2, 3 x 3, 4 x 4, etc.). Each camera is sequenced at a rate
that is equal to the recording speed on the VCR up to 1/20 second. The JK-MX16A offers a wide variety of
features designed to integrate with most any video surveillance system.
Features
• Multiple Screen Displays
In both live and playback modes, the JK-MX16A supports a multitude of display modes including: 2x2,
3x3, 4x4, 8+2, 12+1, picture in picture modes, vertical split screen, horizontal split screen, squash screen
and squish screen. (Refer to page 13 for details)
• Multiplex Recording/Playback
The JK-MX16A is designed to record all cameras onto a single VHS videotape. During the recording
process, each camera is encoded with a digital ID number. For example, camera one is encoded with a
"number one," camera two is encoded with "number two," and so on. During playback the multiplexer looks
for the digital ID number and decodes the signal. The end result is that you can select to view any camera
you wish to view without having to view all of the cameras that have been recorded.
The speed at which the multiplexer switches from camera to camera is determined by the speed at which
the VCR records. For example, if the VCR is set to record in 18-hour modes (also known as 24-Hour
Virtual Real-Time), the JK-MX16A must be programmed to record at the same speed. (Refer to page 22
for details)
• Multiple Monitor Outputs
The JK-MX16A is equipped with two monitor outputs. The main monitor output will display both live and
playback image in any multiple screen display desired including programmed camera sequence. The call
monitor output displays each live camera in full screen mode and can be programmed to sequence at a
rate determined by the user. (Refer to page 28 for details)
• Day/Night Function
This unit has the unique ability of converting a color camera with mediocre low light capabilities into a
black & white camera with excellent low light capabilities for use in low light conditions. This function is
programmable via a timer schedule. (Refer to page 21)
• Alarm Function and Scheduling
This unit is equipped with one alarm-input contact for each camera input. Upon alarm activation this unit
can be programmed to automatically alter recording priority of alarmed camera input and display the
alarmed camera in any desired display mode including full screen. Each alarm input channel can be
programmed to ignore an alarm input by timer schedule. (Refer to page 23 for details) In addition, this unit
has the capability of storing all alarm events in an alarm event log. (Refer to page 26 for details)
