Completed Installation

Installing the Wall Dock

In some installations it may be desirable to mount a single gang control
keypad next to the A0316. To accomplish this, the single gang trim plate
can be installed next to the A0316 in a 3-gang junction box.
Follow the steps below:

Installation Steps

1. Connect all wiring. Use the correct
installation tools: J-110 tool, or
1014 crimp tool.

2. Install keypad and single-gang
trim plate in the far left position
of the 3-gang junction box.
(See details on page 3)

3. Leave off the right side
flange and trim piece.

4. Install the iPod dock in the
left side of the 3-gang j-box.
It will overlap and snap into
the single gang trim plate.
(See page 5 for details)

Completed Installation

Docking the iPod

The dock platform can slide up to hide
the dock connector when the system is
not in use. Make sure the dock platform
is in the down position so the dock
connector is exposed (as shown here).

The sliding dock lever beneath the dock adjusts the position of the
dock connector to create a perfect fit for all compatible iPods (see
page 3 for a list of compatible iPods).

Using the A0505 Remote Control

The buttons above the iBus
label on the A0505 remote
control will mimic the
functions on the iPod wheel.

The volume, mute, power, and source buttons
on the A0505 are designed to control Channel
Vision’s whole-house audio systems such as
the A4603 and P-1044.

Please note that this remote will only function
when your iPod is docked in the A0316 wall
dock. It can be pointed directly at the wall
dock or at an IR receiver that is part of an
external whole-house IR system. An IR-4180
cable can be used to connect the emitter
output of the whole-house IR system into the
IR IN of the A0316 output wall plate. See page
5 of this manual for an example.

We realize that custom integrators way wish to design advanced control systems. To
provide assistance we have published the hex codes for the IR commands (see below).
(IR codes can be downloaded at: www.channelvision.com)

A0316 Serial Protocol

RS-232 Control Code:

For more complex installations, the A0316 supports RS-232 making it well
suited for use with automation systems. Baud Rate: 57600, 8N1 (8-Bit Data,
No Parity, 1 Stop Bit)

The checksum is calculated by adding the bytes together as signed 8-bit
values, discarding any signed 8-bit overflow, and then negating the sum to
create the signed 8-bit checksum byte.
When calculating the checksum of iPod responses, the sum of all the bytes
from the packet payload length to and including the packet payload checksum
is 0x00.
When calculating the checksum of commands issued to the iPod, the sum of
ALL bytes, including the “A36” prefix, as well as the checksum is 0x00.
Responses in the Special Lingo are also calculated in this way.
NOTE: to issue commands without calculating a checksum, you can use the
ASCII lowercase ‘z’ (0x7A) as a wildcard checksum value.

There are two possible responses generated when a command is received:
#(0x23) - This acknowledges that the command was received and it had a

valid check sum.
Y(0x59) - This means there was a length error with the command.
ZZZ(0x5A) - This means that the command was not understood. It could also

mean that the check sum was not valid.

Serial Cable Pin Out

A0316 RS-232 Pins
DB-9P, Female

PC RS-232 Pins
DB-9P, Male

The format of responses is as follows:
# {Length} {Lingo} {CommandID} {Message} {Checksum} {Carriage Return} {Line Feed}

Checksum value

HEX 0D

Message from the iPod

Com ID

The iPod Lingo

Length of the response, measureswhich the Lingo, Com ID, and the Message.

HEX 0A

Message Payloads are shown in italics: 1 2 3 4 5 ... are represent a HEX byte,
followed by [cs] = Check Sum. All understood commands will elicit a ‘#’ (0x23)
acknowlegement, which is not shown in the tables below. Other commands will
also elicit an additional response in the form of a “Return” command.

}

Checksum value

Message from the iPod is 01, so, the Remote UI Mode is “On”.

Com ID is 04, so, this is the “Return Remote UI Mode” message.

The iPod Lingo is 00, which is the basic lingo.

The Length is 3 bytes, which are the Lingo, Com ID, and the Message.

Acknowledge the command was received

The commands below are for simple transport control of the iPod.
There is no reply from the iPod dock beyond the basic ‘#’ acknowledgment.

A0316 Serial Protocol

Example:

The following example describes how to query the iPod database.
There are several database categories that can be queried.
Category (HEX Number)
Playlist (01)
Artists (02)
Albums (03)
Genres (04)
Tracks (05)

All numbers are HEX values.

Note: commands begin with ASCII A36, which converts to HEX:
The database must be reset prior to a query. Use Reset DB Selection: 41 33
36 31 41 E4
Ask how many artists records there are by using the
Get Number Categorized DB Records command.
41, 33, 36, 32, 43, 02, 7A

The iPod will urn Number B
07, 04, 00, 19, 00, 00, 00, 70, 6C, 0D, 0A

d

Get 5 atabase records for artists starting at record index 0, by using the
Retrieve Categorized Database Records command.
41, 33, 36, 3A, 44, 02, 00, 00, 00, 00, 00, 00, 00, 05, 7A

*The commas separate bytes so the largest valid decimal number will be 255
(or HEX FF). 4 bytes are reserved for the record index and 4 bytes are
reserved for the number of Artists requested in each transmission. For
numbers exceeding 255 (HEX FF), use the preceding (more significant) byte.
Examples:
00, 00, 00, 05 = There are 5 records
00, 00, 00, FF = There are 255 records
00, 00, 01, 01 = There are 257 records

To select the 9th record in the Artists database, use: Select DB Record
41, 33, 36, 36, 42, 02, 00, 00, 00, 09, 7A

Connection Tips and Troubleshooting

1) Be sure you have connected the CAT-5 cable correctly. Follow the TIA-568A standard at
both ends. Incorrect wiring can cause distorted sound or prevent the system from working
at all!

2) Be sure you have connected the speakers in phase. Follow the label on the product. Out
of phase speakers can rob the system of its bass. Especially when driving dual-voice-coil
speakers.

3) Trouble with IR control?

a. Make sure you are using the correct remote control. The A0316 will only respond to IR

signals from the Apple Remote produced by Apple Computer or the A0505 produced by
Channel Vision. Other 3rd party remote controls are not supported.

b. Disconnect anything that is connected to the “IR IN” on the output wall plate. Point the

A0505 remote at the Wall Dock and see if you can control the iPod. If this works, you
need to troubleshoot your IR repeating system.

c. Troubleshooting an external IR system: Some IR receivers have a feedback LED that

flashes whenever IR signals are received. If the IR receiver you are using has this
feature, check to make sure the LED flashes whenever you press buttons on your remote
control.

i. If you don’t see the feedback LED, try replacing the batteries in your remote

control.

4) The A0316 is designed to charge the iPod (see compatibility notes on page3). When the

iPod is not playing music, the screen should indicate that the iPod is being charged. If
this does not occur, make sure the power supply is connected to the output wall plate of
the A0316.

5) Observe wiring distance specifications. The maximum recommended wire length

between the wall dock and output wall plate is 350 fee for audio & power.
For meta data output limitations, please reference page 19.

6) If you are experiencing problems with your iPod that occur even when it is not docked in

the A0316, then please contact Apple customer service for support.

7) If you need additional help troubleshooting the A0316 please contact Channel Vision

technical support or check our website for more details: www.channelvision.com.

Stripping and Connecting CAT-5 Wire

CAT-5 cable should be stripped with a proper stripping tool, such as Channel
Vision’s J-110 tool.

1. Place the CAT-5 between the blade and the first notch of the J-110 tool.

Cat5

3. Inspect the inner wires for damage.
If any wires are cut start over at step 1.

2. Rotate the tool only once. Multiple turns

will cause you to cut into the inner wires.
