EIKI A-6

Tested To Comply
With FCC Standards

FOR HOME OR OFFICE USE

To the System IntegratorR

Thank you for choosing Eiki A-6.
The Eiki A-6 Multi Media Port is ideal

for “smart classroom” projector
installations that combine fixed PC
and AV equipment with the ability to
plug in portable devices such as
laptops. The A-6 is a compact, easy
to install integrated wallplate and
VGA-AV switcher that is an ideal
companion to the MCS-1 Multi
Control System.

For your safety

Please ensure that any wiring used to
connect an A-6 to other equipment is
kept clear of mains wiring and follows
applicable local wiring codes. Under no
circumstances may an A-6 be
connected directly to power mains
wiring.

Please ensure that the power supply
you are using meets your local safety
regulations and that its voltage does
not exceed 16 volts DC. Unregulated
power supplies can output voltages
that are well above what is shown on
their label.

Introduction

The A-6 Multi Media Port combines the following
functions:

• Input plate

• Four input Audio-video switcher

• Two input RGBHV switcher

• RGBHV splitter

in a single-gang wallplate. The Eiki A-6 greatly
simplifies installation and cabling and avoids the
need in most cases for video/audio and RGBHV
switchers.

Anyone who has ever had to manage AV
facilities will appreciate these unique features of
the MultiMedia Port:

• A fast-response “Signal Present”
indicator LED for the laptop input helps a
user to quickly set up a laptop so that it
is outputting a signal.

• MultiMedia Ports can be installed in
different parts of a room and “daisy­chained” to create an economical multi­point input solution with minimal wiring
and no central switchers.

• A “Monitor” output allows a desktop PC
to display its output on a projector and
its own monitor at the same time.

The diagrams on this page show the inputs and
outputs that are available on the A-6 Multi
Media Port. The rear connections use screw
terminal plugs to simplify the installation of
fixed wiring.

The Eiki A-6 is an ideal companion for the Eiki
MCS-1 and connects directly to it with the
supplied interface cable.

The A-6 may also be controlled by other
systems. It includes video sensor outputs that
may be read by external equipment. Or the A-6
may be used standalone and locked to any fixed
input arrangement by a combination of
connections on the interface cable.

Please note that the Cable Compensation
provision marked on the rear of the unit is not
implemented in current production.

Input terminals

On the front of the unit there are the following connections:

• One VGA input

• One VGA monitor output. This follows the output of the switcher.

• Two RCA sockets for line audio, shared with a 3.5mm stereo jack

• One RCA socket for composite video input.

The audio and video inputs are accessed together as Input 3. The VGA input is
switched separately. If you want to use the audio inputs with the VGA input you
have to select them separately as AV input 3.

On the rear of the unit there are the following connections:

• One VGA input on HDDB15 connector

• One VGA projector output on HDDB15 connector

• Three audio inputs on screw terminal connectors. Input 1 is a mono input.

• Three video inputs on screw terminal connectors.

• One pair of stereo audio outputs on screw terminal connectors

• One Composite video output on screw terminal connectors

• Two breakout connections from the Control and Power socket for relay drive.

(See notes on the following page for more information.)

Audio input 4 would normally be used in conjunction with the rear PC input.

There is an internal 2 pin jumper that, when linked, converts to output to mono by
combining L and R audio signals.

With no control inputs asserted, AV 1 and the rear VGA input is selected.

Programming an MCS-1 to control the A-6 Multi Media Port

• In the Eiki Control System Editor, select MCS-1 as your device.

• In “Edit behaviour” mode, double-click the key you wish to program. A

dialog like that shown will appear.

• You can choose the inputs of the A-6 you wish to select when the button is
pressed by using the drop-down items in the Multimedia Port section, as
shown.

• Eiki Control System Editor software version 2.7.15 or later has a “Relay
Output” drop-down item that allows you to operate an external relay which
can be used to control a motorised screen or lights, for example.

• Make sure that when you are programming keys that should not change the
state on the A-6 Multi Media Port, the selections are left at the default of
“No change”.

“AV 1 (rear)”
will select A in
1 and V1 in
inputs on the
rear of the unit.

Audio and video
inputs are
switched
simultaneously.

“RGB front” will
select the VGA
socket marked
“Laptop” on the
front of the unit.

Please note that
any audio
associated with an
RGB input must be
selected separately
using the
A/V Selection
drop-down. Audio
for RGB Front would
be selected with
“AV 3 (front)”

Interfacing to the MultiMedia Port.

If you wish to control the A-6 internal switchers in some other way, or configure the
unit as a standalone, fixed input wallplate, you will need to know the control port
connector pinouts for the ribbon cable. They are as follows:

Pin Function Type Comment

1 Relay output Logic Low RL1
2 Relay output Logic Low RL2 (not implemented on MCS-1)
3 GP output 2 Not used
4 RGBHV source Logic Low input Low = Front PC input
5 AV source 1 Logic Low input See table below
6 AV source 2 Logic Low input See table below
7 RGBHV sense Logic output
8 Video sense Logic output
9 GND
10 +24 v Power Any positive voltage from 9v to

30v. DC.
