14.0 REAR PANEL
The DMX512/1990 connector and Mains input connector are described in the “CONNECTING AND
TURNING ON” chapter. DMX512 pin connections are printed on the rear panel of the Atom (below).
Typical dimmer connections are described in Appendix A.
Rear panel layout of an Atom 12/24. An Atom 24/48 has provision for a second analogue output module.
14.1 Mains Fuse
The mains fuse is located in a slide out tray in the base of the mains input socket. Should the fuse blow,
remove the mains lead and slide out the fuse tray. Pop out the blown fuse and replace it with a 0.5 Amp slow
blow fuse. A
spare fuse is provided
in the slide out fuse tray. Replace the fuse if you use it.
14.2 VGA Output (Optional)
The
optional
VIDEO output allows a standard VGA computer monitor to be directly connected to the Atom to
provide visual displays of channel levels, fade times etc. For operational details, refer to the “VIDEO
OUTPUT” section in the “UTILITIES” chapter.
14.3 Expansion Port RS 232c
The RS 232C connector is a serial port that may be used for the following functions;
•
VIDEO TERMINAL / COMPUTER
. A “video terminal” or “computer” may be connected to provide visual
displays of channel levels etc. Refer to the “VIDEO OUTPUT” section in the “UTILITIES” chapter.
•
PRINTER
. A Serial Printer may be connected to provide hard copy print-outs of the Atom memory
contents. Refer to the “PRINT” section in the “UTILITIES” chapter.
14.4 Desk Lamp Connector And Fuse
The optional halogen goose-neck desk lamp is connected to this socket. The socket provides both power and
mounting for the lamp. If you have purchased the optional desk lamp, simply plug the goose-neck into the
connector and adjust the position of the lamp to illuminate the front panel. The desk lamp is separately fused
from the main Atom power supply. Should the desk lamp fuse blow, replace it with a 1 amp fuse.
14.5 Analogue Output Connectors (Optional)
The
optional
analogue outputs provide an analogue control voltage (0 to positive 10 volts or 0 to negative 10
volts) on a one-wire per channel basis to control older analogue dimmers. Several different types of connector
are available. Wiring details of the analogue connectors are given in “APPENDIX B”.
14.6 Mode Switches
The DIP MODE switches on the rear panel provide the following functions;
•
Switch 1 UP. The operation of the Yellow Submaster is inverted.
•
Switch 1 Down. The operation of the Yellow Submaster is normal. See the “UTILITIES” chapter for details.
•
Switch 2 UP. The selection of the Softpatch is allowed.
•
Switch 2 DOWN. The selection of the Softpatch is NOT allowed. See the “PATCH” chapter for details.
14.7 Audio Input
The audio input connector accepts a line level audio signal up to 1 volt rms. An automatic gain control feature
ensures reliable stepping with varying audio levels. The bass frequencies of the audio signal may be used to
control the stepping of a chase and so synchronise the chase to the beat of music. See the “CHASES”
chapter for details.
