Trigger older flash?

[Darryl Roberts]

Hi, do you know if there's a cable that can connect to these prongs to trigger flash?

Bi-post connector.

Have a cord made for it and your flash connector by Paramount flash cords.

B&H sells the paramount cables as well:

Problem is getting it to trigger the 1/8 inch Pocket Wizard

Or just buy a TV cheater cord or an electric razor cord.

Paramount could probably make that for you.

Verify that an electric razor cord will fit then spice that to a 1/8" mono plug.

This is the thing to do; I have mine quite short and hang them in front of the camera, for my microsync transmitter.

Paramount can custom build a cord with any ends you want, leastwise, last time I looked. A bi-pin to mono plug for Pocket Wizard might be a standard item for them though, there are probably more than a few of us that could use something like that. Another option might be to get a bi-pin to PC-female cord, and plug a standard Pocket Wizard cord into it.

Those Bi Post pins are corroded/tarnished. Clean/polish them with metal polish, paste type. Do not unscrew them as they hold contacts in place inside the shutter.

They might work (mine that look like that work)... but GREAT advise! I’ll probably polish mine up.

A problem with old very shutters is that internal contacts usually were intended for higher voltages then the ones sourced by modern flashes. Each metal type requires a certain voltage level to start electrical conduction, it can some microvolts or several volts. Some time the internal mechanism operates are he contacts are in touch but signal is not transmited becaue of the natural oxyd layer is not broken by the low voltage sourced by a modern flash.

We may fire several times the shutter or we may clean the internal contacts to get an stable operation, but soon it will fail again. Personally I solved that by making an interface electronic circuit working at higher voltage and this one fires the strobe, it's a quite simple interface circuit.

Here different solutions are debated: https://www.eevblog.com/forum/projects/old-camera-speedlight-low-voltage-trigger-conversion/

Perhaps some standard adapter circuit is there... but I know/remember none.

Thank you for solving the problem.

I just got that exact cord from Paramount this past week.
