Usage Information

More info about device  :

This is Marantz's cheapest model that has rs232c connector and surprisingly, it has two way communication capability - that means that when user does something on receiver's button or IR remote control, you get status messages about changes...

There are few different documents about RS232 protocol on this device. This one worked on mine, luckily is ASCII based and therefore much more user friendly...

First I've closely examined existing templates for Yamaha receiver, RS232 Plasma and tried to learn things. Since there is currently no special screen prepared for control of Audio/Tuner receiver device, I decided to use 'TV - LiveTV' device with template #1751, that already has associated media screen for tuner control (it's meant for TV tuner control, but is close enough for a start)...

I have also decided to use Marantz in Multiroom configuration (7+1 output is in this case split to 4+1 output ("Zone Main") and 2ch stereo output ("Zone Multiroom"). There is also third zone - "Line Out", but this is only preamp output of Multiroom Zone, but can have separate volume/mute control. Template has currently basic support for all 3 zones. There are still few things to be added, but I'm learning Ruby slowly and have few problems, so maybe I will get some help from more experienced guys...

The whole idea of implementation is to have 3 separate zones (each represented by "Zone" child devices (extended template #1867), to whom you can connect your audio sources by audio pipes. Currently squeezebox devices and other HW players will work ok, there are some slight problems with ordinary Xine player on Onscreen Orbiter, cause whole Orbiter is connected on pipe and when the media stops playing, On command for Orbiter instead of Off for player is propagated through pipe, so your amplifier stays On for some time even after stop...


LinuxMCE Developers: Can you please add new media screen for such type of devices (http://plutohome.com/support/mantis/view.php?id=3151) and maybe even document procedure on Wiki. It would ease similar contributions from other users...

Description of needed templates

I hope that this template will be available with stock LMCE distribution, so you won't have to create that template from scratch. Template is called "SR Series MultiRoom RS232" to be different from existing template for Marantz in 7+1 configuration ("SR Series RS232"). The main difference between those templates is that this template is more complicated, cause it gives you independent controls of more zones and therefore it has a bit different logic (for example main general power is switched off only when all zones are muted, zones are switched on/off only by muting them)

For template to be functional I've made certain extensions to existing template for "Zone" that I hope will be usefull also to others...

Settings are factory defaults and should't be changed (9600 baud rate, 8 bits, 1 stop bit)...

'Edit Ruby code' (on template page)

'Determining proper set of inputs'

I've added all inputs that are present on device. There is also a special input called "FM" where I connected Live TV embedded device to be able to control tuner functions (tuning/searching up/down, go to preset stations, etc...)


'Set proper set of commands'

Basically I've added command groups :

Ruby Internal Commands
Standard Receiver Command
Volume Commands

and added some needed commands (important is command to tune to certain FM frequency, so you can later add scenarios for tuning to certain FM stations....)


'Add Ruby snippets to commands'

I've created new IR/Codeset group called "Marantz SR Multiroom RS232", although I'm not sure how to handle it. Have also edited coresponding Ruby snippets for each command. Basically those are just simple strings that get send on rs232 to take proper action on device according to received command from LinuxMCE... There are also a lot of other functions that help :

- determining for which child zone command is targeted
- to "normalize" volume levels between Marantz's internal dB units and range of 0-100

'TV - LiveTV' device with template #1751 as child device'

TV- LiveTV device is automatically added as child to parent device, because I have selected it for connection to FM input. Therefore nothing more is needed to do, except support for commands that can be sent from LiveTV Orbiter screen.

Important device data and parameters for "Zone" template (#1867)

I've extended that template to be useful for multizone audio devices. Basically such device should include everything that is needed to control Audio Zone (input switching, A/B switching, volume control, On/Off Commands). But bevare, those devices are embedded - that means that they don't do anything - they are just empty boxes you add to parent device for representing each audio zone. All processing of commands should be done in parent device. But using Zones, you can easily connect devices via pipes, create scenarios with sending commands to certain devices/zones etc...

Important extensions to Zone template:

- added common audio inputs (so input switching can be implemented)
- added commands (volume, inputs, on/off, A/B switching)
- added "controlled by" category of Amps,...

Have added following command groups are used in Zone :

A/B switching           (select A, select B)  	
Generic IO Commands 	(On, Off)
Inputs 	                (common inputs on audio receiver)
Radio 	                (command for tuning to certain radio frequency)

Zones are automatically added to parent device by having this on parent template :

Device Template Related
#1867 	Zone 	My Child 	Extra 	12|2|186|Line Out 	
#1867 	Zone 	My Child 	Extra 	12|1|186|Zone MultiRoom 	
#1867 	Zone 	My Child 	Extra 	12|0|186|Zone Main 	

3 child zone devices are automatically added to parent device.

12|2 means that device data #12 (Port) will have value of 2 and that Line Out is description (data #186) of that zone 2.

Using device

Add device based on created template

Specify COM port for it

Assign it to new room

Assign also child zones to rooms or EAs.

Specifiy Audio pipe connections to inputs on zones

In my case, I connnected output of Hybrid Core and one MD to different inputs (CD and DVD) and different zones. In that way, when you press play on each source, commands to setup inputs on SR5600 should be done automatically so you can hear music right away....

Now reload Router, regenerate Orbiters and new device should appear in specified room. On click you get into control screen where you can control device 'manually' beside automatic handling described above.


Prepare Media scenarios

Beside from commands that are sent from Orbiters, you can also create various media scenarios, with On/Off, Volume, A/B, Input switching (you can for example put both (all three) output zones to same source - no sync problems !!!...

Where the problems arise

I'm describing few potential problems I'm facing in my setup. Will be happy on any opinion or guidance...

Proper support for connecting On screen media player (MD or Hybrid) to Amplifier

Currently it seems that media players cannot be connected to amplifier in a clean way. The problem is in routing of volume and on/off commands through audio pipe. In short, the problem is that currently you have to connect hybrid or MD to audio pipe, but when media ends in that EA, Off is sent to Xine player, but On command to Orbiter and this On command also gets propagated on pipe - so Amplifier turns on, instead of Off. Also when screen saver jumps in, there is also possibility that Off command will get to the amplifier, which is not correct if you're listening to media... There are at least few threads on forums and Mantis, if you want to read more...

Some older discussions

Below I'm leaving some older discussions about potential problems. Not sure if they still hold...

Proper support for MultiRoom feature

Device supports separate stereo device on two back channels. That means that with enabling multiroom feature, basically you get two devices (one 4+1 and other 2 channels) that can have separate or same sources and different volume levels. I'm not sure how to properly setup support for such feature - will try to add another child tuner and set it up to control only second separate channel. But it seems that I cannot get two screens for two tuners/zones in one zone, but as child devices they need to be in same zone (as I was advised from LinuxMCE guys or am I missing something).

Cannot add device to Entertainment areas in same room

I have SR5600 assigned to room. Assigning it to separate entertainment area in one of the rooms didn't work (menus didn't appear on Orbiters). Also I should put two child devices (tuners) into separate audio entities, but that would probably not work at this time...

I'm not sure what is the real problem and what is proper solution. I'll kindly ask LinuxMCE guys to guide me here....

Pipes can be connected only to one device

It seems logical, but in case of such devices it's also restriction. I have Hybrid and MD output connected to one input on receiver (although have virtually two devices and would like to have an option to be able to connect two audio pipes from one source). There is also Y connection splitting line audio signal from MD to TV and receiver. Also pipes feature of automatic handling of routing (if you for instance press play on MD, then receiver will be automatically switched to proper input, so you can hear music) can sometimes become restriction. For instance if I use two separate inputs, then hybrid is assigned to one of them and volume control will change main volume and play/stop will reroute always to hard-coded route, regardless of current state, where it might be better rerouted to second device output, cause first one is occupied with Movie....

Pipes and automatic routing is not always a good thing

For instance, user is listening to audio, then he decides to switch manually receiver to FM station. MD or hybrid keeps playing its music and shuts receiver off when it finishes... If we want to properly deal with this situation, we should have two way communication and a lot of code to sense user actions and set everything according to that - but that's a lot more of work to do....


This is schema for my setup and I'd kindly ask for further guidance. There are quite few potential problems with more sophisticated setups, but I feel that this will be common practical situation in deploying LinuxMCE system...

Discussion on how to properly implement template for such device ?

Currently, I've implemented such template using child Zone devices and it seems like a step in proper direction. But we will see. I'm also presenting discussion below that describes where the problem lies...


After a year or so, it is not clear to me how to properly implement template for such device that includes all sorts of "embedded devices".

Let me start with basic description of capabilities :

1. Outputs

A. device as single audio output

 A.1 7+1 channel amplified output
 A.2 Line out that has same music as A.1, but can be swithced on/off and volume controlled separately with serial commands

B. device as multiroom audio output (two separate and controlable outputs) - this is how I use it at the moment to feed 2 audio zones)

 A.1 5+1 channel amplified output
 A.1 2 channel amplified output on last two speakers terminals with own commands for volume,source and other control...
 A.3 Line out that has same music as A.1, but can be swithced on/off and volume controlled separately with serial commands 

So basically to cover both cases I have 3 possible outputs :

 O.1 normal main audio output (either 7+1 if A and 5+1 if B)
 O.2 secondary stereo amplified output (last two outputs from A.1 are made as separate amplified stereo output with its own serial commands, volume and source control..)
 O.3 Line out that has same music as O.1, but can be switched on/off and volume controlled separately with own serial commands, so could be used for externally amplified replication of main output...

Basic distinction is that all 3 possible outputs have separate serial commands for volume and source control(not O3) etc...

2. Inputs

Outputs O.1 and O.2 can select one of possible sources independently - (I'm not sure if they can select separate FM stations on Tuner input) - so basically this is true multi channel audio feature. If they select same source, then same music is heard on each... But again serial commands for selecting inputs differ for each output....

LMCE has already prepared FM and AM Tuner devices templates (which I don't understand quite well, but no docs available), but I'm not sure if they are usable in such situation.

3. How to make usable template out of this ?

What I'm currently thinking is : - Marantz receiver being parent device - have child devices for each output (O.1-O.3), each from different template, cause they have separate commands for each

But questions arise : - each output could be placed into separate audio zone - but I'm not sure if this can be done with children of same parent ? - how to dispatch commands to each child ? - is it convenient to use tuner devices as well ?

And probably there are some more problems to be solved.

Any opinion ?
