Technical Note #300 - Remote Dump Operation FAQ

Many BD500 and earlier delay unit installations require activation of the DUMP button from somewhere other than the front panel of the unit.  This page consolidates a lot of the information found in our manuals and elsewhere, and provides information on obtaining the "official" DUMP button and related parts.

REMOTE DUMP

Q:  I want to remote the DUMP function on my BD500  How do I do this?

A:  The BD500 has a "basic" remote control and an optional, much more elaborate, remote control.  You must first determine which is in the unit you wish to control.

The BASIC remote control is described in detail on page 21 of the manual.  You can identify units with this remote by the presence of a single DB15 connector surrounded by two unused DBx connector cutouts on the rear panel.
The OPTIONAL remote control is described in detail on page 23 of the manual.  You can identify units with this remote by the presence of at least one additional connector next to the DB15 in the middle cutout.

In both cases the manual will provide full information on using the remote.  This FAQ is for remote DUMP using a pushbutton switch only.

Q: My unit has the basic remote control and I need the functions of the optional remote control.  Can I upgrade?

A:  Yes.  Please contact Eventide for information on upgrade paths.

Q:  I have the BASIC remote control.  How do I remote the DUMP function?

A:  Referring to Appendix B of the manual, page 21, the following connections must be made to the female DB15 connector:

Short Pins 5 and 6 together.  This grounds the - side of the DUMP relay coil.
Connect a single pole, single throw, normally open push button switch contact between Pin 9 (+5V) and Pin 4 (the + side of the DUMP relay coil).

Closing the push button switch energizes the internal DPDT relay.  One set of contacts is brought out to the rear panel.  The other internally closes the DUMP switch contacts just as if a person pressed the button on the front panel.

Q:  I've done this and it works as it should.  However, I've noticed that pressing the DUMP button on the front panel doesn't close the rear panel relay contacts.

A:  The remote DUMP relay is only energized by the remote dump switch.  The optional remote control gives you more control versatility.

Q: My unit has the optional remote control.  How do I remote the DUMP function?

A:  Referring to Appendix C of the manual, page 23, connect a single pole, single throw, normally open push button between Pin 2 (remote input 1) and pin 8 (reference supply).  Please refer to the manual for necessary programming instructions!  The remote DUMP will not work until properly programmed.

DUMP SWITCH

Q:  I'd like to remote the DUMP switch on my Broadcast Delay and I like the nifty DUMP button on the Eventide unit.  Can you sell me a switch and cap to use on my remote?

BD941, BD942

Q:  Can we get one of the 5 pin DIN plugs and if so, how much?

A:  We can supply mating connectors for the DIN connectors on the back of these Broadcast Delay lines.  The BD941 and BD942 use the same connector.  The mate bears Eventide part number 312281 and the price is $10.00.  Please note we have a $25 minimum order policy.

BD980, BD955

Q:  Can we get one of the 8 pin DIN plugs and if so, how much?

A:  We don't know if we can supply mating connectors for the DIN connectors on the back of these Broadcast Delay lines.  It's been so long since anyone has asked that the parts aren't in our "system."  The BD980 and BD955 both use the same connector.  If you need one, let us know and we'll see if we can find any.  They will be $10 if we can.  Please note we have a $25 minimum order policy.
