Introduction MicroTC was introduced to answer the need for a small, economical but still very capable Programmable Media Controller, particularly for use with Home Theatre and also for applications where there is no audio or video requirement. In fact, it can function in a similar way to PLCs if desired. • • •
MicroTC is simply the programmable controller section of a full Theatre Commander unit. It has all the same capabilities without the inbuilt audio and video systems. It has no front panel controls, but there is a socket for connecting an optional diagnostic control panel.
For system integrators already familiar with TC, this manual covers the points of difference and presents some typical applications - it is not intended to be complete in itself but, for programming purposes, to be used in conjunction with MAN0008. This manual will concentrate on • • •
Choosing your ancillary equipment Connecting this equipment for control purposes Guiding you through the process of changing a standard Theatre Commander template to suit MicroTC in a typical home theatre environment.
For detailed information on the many advanced capabilities of MicroTC, other Command Systems products that form part of the system and the software tools that tie it all together, see MAN0008. Thank you for purchasing a Command Systems product! We know you’ll be pleased with it!

How to program MicroTC Because the MicroTC lacks the full-size unit’s inbuilt audio and video facilities, any references to these in existing programs, templates and macros have to be changed. Fortunately, this is quite easy because you can use the Resource Usage dialog to find all the places where you need to make changes. Of course, your application may not need any audio controls, in which case there’s nothing to do! There’s no reason why unused items can’t be left in place – they just won’t do anything. But it’s quite likely that you will be using a remote-controllable audio system of some type. This is probably going to be an infra-red controllable “Hi-Fi”-type item such as an AV receiver or modular Music System. These units often have video switchers in addition to the normal audio input selections and volume control. Another possibility might be to use the audio functions of a projector or TV monitor. In any case, TC’s normally inbuilt audio functions will need to be replaced by “Send Serial Code” commands that will activate the appropriate functions. Here’s how I’d suggest you go about it:
1. Choose and Load a Codeset You will need to use a codeset to suit the equipment you are using and one that already has the Input select and Volume Up/Down commands. If there is nothing suitable in the library you may have to sample your unit’s remote control.
2. Change the Volume Control in the Function List Change the Audio Control Add and Audio Control Subtract items to Send Serial Code statements.
3. Change the Input Select macro I suggest you add the necessary Send Serial Code commands and leave the existing Audio Switch, Video Switch and AV Switch commands in place. This is because other things, such as the Control macro, may rely on them. That’s all there is to it!
