ITC Delta 3 triggered start

[SFM-Ptgal]

Here I am again...

Following this information:

Delta I, II, III Playback Remote Control pin-out:
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

How can I make my ITC DIII playout carts automatically 1-2-3-1-2-3-1-2- so on, so that the TER pulse triggers the next deck while the SEC is kept for audio mute. Is this possible?

TIA,

Pedro

wire pin 12 on machine 1 to pin 2 on machine 2; pin 12 on machine 2 to pin 2 on machine 3, pin 12 on machine 3 to pin 2 on machine 1.
I normally put a double pole switch in each wire to break the sequence, and wire the other pole to an LED which lights when sequenceing is in operation. Some folks skip the switch, and simply leave the next deck empty to preclude a start at the end of he preceeding cart.

Thank you Littlejohn, I'll give it a try...

 

[SFM-Ptgal]

Nope... it didn't work. I can ear the TER recording and detection but it doesn't trigger anything Have we missed something?...

 

[SFM-Ptgal]

Just add this: I've shortened pin 1 and 2 with the remote start in mind. It didn't work...

 

[littlejohn]

OK, something's busted in it, or the pinout isn't correct. When the short of 1 to 2 makes it go, then the tertiary ground will also. I last played with Deltas in the late 70s, my mempry of their wiring and quirks isn't great. Graduated to Tomcats thereafter, which had their own quirks.

ooops... I've just tested the shortened pin 1 and 2. It worked. The problem was that the 1st time I did it the machine was leaned towards me so the solenoid didn't pulled up. With this problem solved any clues about the main issue?

Thanks for any help!!!!

Measure pin 12, and be sure it is in fact going to ground when the tertiary tone hits. If it doesn't fall low enough, series pin 2 through the tertiary relay NO to ground.

What should I measure, how, what pins should I use? Sorry I'm not into electronics :-\

Ahh but you are getting there That's part of the fun

Sorry I can't help with your problem though, as I don't own a Delta.

There's nothing more fascinating than a studio filled filled carts and cart machines compared to these cpu, ram, tft's, lcd's, 0100110110111001, blah blah blah days ;D

Hehehehe, unless you are working in a studio still using carts, that happens to reside at or near a fault line. Earthquakes + Racked Carts = klunkityklunkityklunkityklunk! ;D

No need for a earthquake to drop a cart (pile) on the floor ;D Well... let's hope that our cart babies get fixed asap... ;D

Yeah, it's more fun to precisely stack an hours worth of carted material, only to accidently knock 'em over... while you're on the air! ;D

I'm not Littlejohn...but I'll try to help: Go to the local electronics store (whatever the equivalent to Radio Shack is over there) and purchase a digital voltmeter - also known as a DVM. The older version was a VOM - volt-ohm milli-ammeter - that is also usable if a DVM isn't available.

When you get the meter, turn its selector knob to the "ohms" position, connect one side of the meter to Pin 12 (as littlejohn suggested) and the other side to ground (the case will do). See if the meter reads zero when the tertiary tone hits.

Nooope... Tips on the pin 12 and 1 (=case) the TER tone didn't move the "needle" on the DMultimeter (Ohm, several scales tested) Pin 1 and case shunted gave a zero reading on the display... as it should, I think

Could you give me a comprehensive tutorial how to... What should connect to what, etc... Sorry for my insistence

 

[littlejohn]

Try connecting the wire you had on pin 12 to pin 13 instead. That's the realy contact which closes on the tertiary tone. You don't list Relay Common on the pinouts, I assume it is logic ground, which ios already connected. I'd also connect all three logic grunds together. The three sets of electronics may be isolated. (I last messed with Delta machines in 1980, my meory isn't all that good over 27 years,......)
