JP1 Remotes

[jonpo]

A search did not uncover any ideas on how others have handled conflicts between devices which have warring protocols and dominating Combiners.

The remotes are 15-1994s (VPT only works for CBL on this model, so volume control has to be coded for the other devices).

Protocol Clash:

- The Sony LCD requires Sony 12/15/20 protocol with 2-byte codes because several commands use a mixture of device types under Sony15.

- Two Tivos (one satellite/one OTA) require the Official protocol.

When a Tivo was selected, none of the TV commands (Volume/Mute/Aspect) responded. The KeyMoves were in place for them, but did not work. Setting the TV controls as External Functions did not help either, so assumed the protocols were bashing heads.

Combiner:

Using a combiner seemed like a way out, so set up two sets:

- Tivo Official Unit 1 + Sony 12 Device 1 + Sony 15 Device 64 --> CBL
- Tivo Official Unit 2 + Sony 12 Device 1 + Sony 15 Device 64 --> VCR

There is a combiner for each Tivo BUT only the last protocol loaded into IR will work. CBL and VCR wind up as synonyms of each other, so only one Tivo can be controlled.

Assigned Device

My workaround for the combiners was to define P&P as Sony 12/15, and KeyMove the P&P/TV commands for the Tivos. Everything has worked fine since because P&P/TV was not invoking a protocol.

- TV |TV |Sony12/15/20
- CBL|CBL|Tivo Official (Unit 1)
- VCR|VCR|Tivo Official (Unit 2)
- P&P|TV |Sony12/15

This solution wastes memory and a device. I want to recover P&P for a more useful purpose than faking out control of the TV when Tivos are selected and would welcome any ideas on:

a) How to have Sony12/15/20 commands execute when a Tivo is selected.

b) How to have two Tivo/Sony Combiners coexist rather than one overwriting the other in IR.

Alternative suggestions on how to configure would also be welcomed.

I think this would be a lot clearer for us if we could see your IR file.

Two points...

1) VPT works in TV, VCR and CBL modes, just as long as the setup code assigned to each of those device buttons uses the native state (ie, you have a VCR code assigned to the VCR button, and a TV code on the TV button, etc. If you change the device type, you break VPT.

You can actually make VPT extend to a 4th device mode if you make the VPT device one of the other device buttons (eg, CD, AUX, etc).

2) For the device combiner, you want to make one protocol that has all the info for all of the devices that you want to combine. Then you can make multiple upgrades that use this protocol.

Tivo 1 is Cable on CBL and Tivo 2 is VCR on VCR but only Tivo 1 has volume control. I'll look deeper, see if something else may be amiss.

I like that wrinkle.

Brilliant solution, problem solved.

Thanks
