Showstopper 3 E-Stop Hub Reference Manual
Published 4-14-20
INSTALLATION
The Showstopper 3 E-Stop Hub is intended to be rack mounted in any standard 19” rack. Feel free to
install it along with other Showstopper devices, a rack PC, a storage drawer for the Showstopper 3
Consolette or in racks with your Stagehand controllers. It can also sit on the operator desk or on top
of a Stagehand controller - just be sure it is secured to avoid falling down or being accidentally
engaged.
MAKING THE CONNECTIONS
As with all our devices, they need to be connected to function.
INPUT POWER
Connect the IEC cable to mains power and to the Showstopper 3 E-Stop Hub. The power connection
must be constant, loss of power to the Showstopper 3 E-Stop Hub will stop all movement to any
connected Stagehands. We recommend adding in a Battery Backup to avoid power loss issues.
SHOWSTOPPER E-STOP OUTPUT
Each Stagehand and smart machine requires a direct connection to a Showstopper 3 Base or
Showstopper 3 E-Stop Hub. The Showstopper 3 E-Stop Hub includes 10 E-Stop connections. These
connections are made with a Neutrik 5-pin XLR cable. There’s no tech wizardry here, any 5-pin XLR
cable will work as long as the polarity is correct. The 5-pin XLR cable is not a DMX signal, but rather it
was chosen as a convenient cable that is prevalent in many venues so you should always be able to
find a spare cable when needed.

ACCESSORY INPUT/OUTPUT
The Accessory output provides power (+24VDC) to the accessory devices as well as the Remote
E-Stop capability. This connection is a standard locking Harting connector (IRC 21mm x 21mm (3A)
12P 10A). This connection is designed to allow devices to be daisy chained together. However, at the
