Aiphone MYW-MD/B User manual

Brand: Aiphone

Model: MYW-MD/B

Type: User manual

Aiphone MYW-MD/B is a versatile video modulator/demodulator that allows for the integration of CCTV cameras and standard monitors with Aiphone's MK and MY series video systems. As a modulator, it converts a standard CCTV camera's signal to a 2-wire signal compatible with Aiphone monitors. Conversely, as a demodulator, it converts the 2-wire signal from an Aiphone video door station to a standard coaxial video signal for display on CCTV monitors or distribution through a cable network.

- INSTRUCTIONS -

The MYW-MD/B adaptor converts the video from a 2-wire signal to a standard coaxial video signal

(Demodulator mode). It can also be used to convert a standard CCTV camera's signal to a 2-wire signal

(Modulator mode). The MYW-MD/B is compatible with Aiphone's MK and MY series video monitors.

NOTES:

1. In the above system example, the CCTV

cameras are addressed by pressing the

MONITOR button on the MYH-CUB. Press once

to turn on camera 1 (MK-DBC), press again to

switch to camera 2 (CCTV #1). Pressing

MONITOR a third time will switch to Camera 3

(CCTV #2), and a fourth time turns the monitor

off.

2. The LE-DA will become active by selecting

station #9 on the LEF-10C. Selecting this station

will also activate CCTV camera #2. The camera

will not activate when the LE-DA calls in.

System Configurations:

1 Aiphone video door station and 2 CCTV cameras

2 Aiphone video door stations and 1 CCTV camera

Optional:

Part #261380 - Video Output connector for MYW-P3L.

(Provides a 1V peak-to-peak video signal output when

the Aiphone monitor is on.)

TO POWER THE CAMERA:

(1) WHEN IN USE

- Install a switch or relay contact in series with the "+" terminal from the power supply (see diagram.)

- Solder a jumper between points labeled AA on the MYW-MD/B main PC board. (see illustration)

This allows the camera to be activated manually, or when the relay contact is activated from a separate

source.

(2) CONTINUALLY

- Solder a jumper between points labeled AA on the MYW-MD/B main PC board. (see illustration)

This will provide continuous power to the camera, which may cause the camera to be warm.

Note: Continually powered, the overall life of the camera will be reduced and condensation may occur.

OPERATIONS

MODULATOR:

Using the MODULATOR to Integrate a CCTV camera with an Aiphone 2-wire video system:

1. The view from the CCTV camera can be seen on the Aiphone MY monitor by pressing the MONITOR button. With

multi-camera systems (MY-2CD, MYW-P3CB & MYW-P3L), the cameras will come up sequentially. (e.g. One

press of MONITOR button brings up camera 1, second press brings up camera 2.) After the last camera in the

system is activated, the next press of the MONITOR button will turn off the monitor. If the monitor is left on, it will

automatically time out after 2-½ minutes.

2. When using a CCTV camera with the LEF/MY system, an audio sub station can be installed near the camera to

provide audio monitoring. The sub station and camera are activated simultaneously from the LEF master station

through the connection of the "K#" terminal from the LEF to the MYW-P3L adapter.

DEMODULATOR:

Using the Demodulator for VIDEO OUTPUT with the Aiphone 2-wire video systems:

1. When the call button is pressed on the MK door station, the inside monitor station will ring and the picture will

activate. At that time, the video signal out of the MYW-MD/B adaptor will be present, and the picture can be seen on

the monitor(s).

2. When the MONITOR button on the inside Aiphone station is pressed, the picture will come up for approximately

2-½ minutes and video signal will be sent to the monitor via the MYW-MD/B.

3. The video signal can be connected to any receiving device that accepts a composite video signal (75 ohm, 1V

peak-to-peak). This could be a standard CCTV monitor, a video input on a switcher or a multiplexer system that

modulates the video onto a cable TV channel. To take the video signal directly into a TV, use a spare video input

or go through the proper modulator.

Using the Demodulator to integrate the MY video door station with a standard CCTV monitor:

(No audio communication or PanTilt is possible with this application)

1. To view the camera location at any time, the camera must be powered at all times, or a switch must be installed to

turn it on. To do this, the PC board must be modified by adding a jumper wire in the location indicated on the wiring

diagram on page 3.

2. There is no PanTilt control of the camera when used in this application. To adjust the angle of the MK camera at the

time of installation, remove the Lexan® dome and move the camera head to the desired angle. Replace the dome

and install the unit.

3. If the camera is powered continually, there will always be a video output from the MYW-MD/B. There is no audio

communication possible through the door station. This application will shorten the life of the camera.
