ITC Delta: The show must go on...

S

SFM-Ptgal

The Delta cart is now running with automatic sequence upon the TERC tone. Thanks to those who helped me on that challenge...
Now a new challenge: I want to make a remote control with pushbuttons of this kind:

http://www.canford.co.uk/commerce/resources/catdetails/3160.pdf

The start/stop contacts issue is solved. Now I'm missing the lamp pin contacts, where should I connect them? Start and Stop remote lamp.

1 - Logic Common, Switch Ground
2 - Remote Start (Run Ground)
3 - Remote Cue Switch
4 - Remote Cue Lamp
5 - Remote Stop (Stop Ground)
6 - Remote Run Lamp (Ground)
7 - Remote Read Lamp (Ground) - Follows ready lamp function,
when lamp is at ground. When lamp is on, signal is at ground.
When lamp is off, the open collector transistor is off.
CAUTION: ready ground follows condition of front panel
ready lamp. If ready lamp is strapped to flash ready
ground will change states synchronous with front panel ready
lamp. Maximum open circuit voltage is 25VDC, maximum
current at 200 ma.
8 - +5 Volts
9 - Auxilary Start Pulse - momentary (100 msec) pulse to
ground upon start of cartridge - open collector. May
be used to start an external clock or timer. Maximum
open circuit voltage is 25VDC, maximum current at 200 ma.
10 - Secondary Cue Relay (Open Collector) - 200 ma switching
current (sinking), maximum 25 VDC open circuit voltage,
switches to ground upon sensing of secondary cue.
11 - Secondary Cue Relay (Normally Open).
12 - Tertiary Cue Relay (Open Collector) - switches to
ground upon sensing of tertiary cue.
13 - Tertiary Cue Relay (Normally Open).
14 - Cue Audio Output - Nominal voltage is .5VRMS
15 - Cue Audio Ground

Thanks again!!!!
 
You'll need something to power the lamps. A wall-wart power supply will probably be OK, but being unregulated it may get dimmer when you have more lamps lit. If you use LED lamps, that may not be an issue.

Run your + voltage source to the lamp + terminal.

Run your - voltage source to station ground.

Run pin 6 of the connector to the lamp - terminal.

Pin 6 goes to ground when the machine is running, which turns on the lamp.

Great suggestion about using LED's! They'll last a whole lot longer than miniature bulbs.

Plus, they are brighter! 8) 8) 8)
