Frequency Shift Keyed (FSK) /

Remote Terminal Unit (RTU)

Preliminary Printed February 27, 1999

This is an Animation system with 128 digital outputs and (optional-

ly) sixteen 0-10 VDC analog outputs. It can be used in stand-

alone applications using its on-board EPROM or an external

source of FSK data for program storage. This unit can also be

used as an output device attached to a PC•MACs animation sys-

tem, receiving data sent to it through the DMX-512 or FSK inputs.

The FSK/RTU can be mounted in 1-3/4” of standard 19” rack

space. It requires 4-1/2 “ of space behind the panel. Power re-

quirements are between 12 and 24 VDC (18 VDC or greater if the

analog output option is installed). The current requirements are

determined by the loads attached to the unit. The FSK/RTU unit it-

self draws between 350 ma. and 1 amp, depending on the

number of front panel LEDs on at any one time.

This Animation System is used in one or more of the following three

modes:

1) Frequency Shift Keyed (FSK) Data Playback: To play animated shows

which have been recorded on any standard audio tape, Compact Disc,

LaserDisk, or other source of audio data. Sixteen to thirty-two 8 bit channels

of data can be played back using this unit. FSK data is normally generated

using a PC•MACs Animation Control System. When operating in this mode,

three relay outputs and/or the serial port can be used to start, stop and

rewind a tape deck, LaserDisk or Compact Disc players. Delays between

shows can be set for up to 9,999 seconds.

2) Remote Terminal Unit (RTU): Receive DMX-512 data transmitted by a

PC•MACs animation Control System, or any other source of DMX-512 data,

and convert it to individual digital outputs and (optionally) sixteen 0-10 volt

analog outputs. FSK/RTUs can be used to temporarily take the place of Brick

Animation Control Systems when programming a show from a PC•MACs sys-

tem. A single DMX-512 twisted pair is often more convenient to handle than

a multitude of temporary J6 ribbon cables.

3) Stand-Alone Animation Playback: A sequencer feature allows the unit

to play a show from an on-board EPROM memory. The FSK/RTU can be set to

play whenever either of the two data sources above stops. This allows an ani-

mated show to continue running in an ‘attract’ or ‘keep alive’ mode when it

isn’t playing any of the regular shows. This mode of operation can also be

used if you just need to run a single show continuously. The sequencer

EPROM is programmed using a PC•MACs Animation Control System.

The FSK/RTU can use this to verify that the data received from PC•MACs has no transmission errors in it. If you address a FSK/RTU or other DMX-512 device to addresses 256 or 257, you will see this verification data displayed as a flickering pattern. Note that at frame rates higher than 40 FPS, not all 256 channels will be transmitted through the DMX-512 output.

These simply snap on to an entire cable, automatically ‘displacing’ the wire insulation and making contact with the wires within. This means that an entire 40 wire cable can be terminated in seconds. All connectors are polarized, to keep them from being plugged in backwards.

You should treat each 1/4 J6/A as an individual, and not cross the outputs or supply lines from one 1/4 J6/A to the lines from another. Doing this won’t cause any damage, but can reduce the protection for the outputs that the circuit breakers normally provide.

Whenever it hears valid data, it will start decoding it and sending it to the outputs. This means that a show can be started at any time by simply pressing the 'Play' button on the tape deck (or LaserDisk or Compact Disc player) that supplies the FSK data.

All characters are sent in ASCII. All numeric values are sent in HEXadecimal (HEX for short), and consist of one or more ASCII characters (0-9, A through F). The case (as in upper and lower) of all input is important. A lower case 'a' signifies a command, while an 'A' is a numeric value.

You can even build up a string which will tell the LaserDisk player to search for another frame on the disk and freeze or start playing from that frame. If no command is given to the LaserDisk player at the end of a LaserDisk show, then the player will continue playing along until the end of the disk is reached or another command is received.
