Impulse 2123 - Manual (Page 13)

SeaLATCH™ USB
The 2123 integrates a patent-pending SeaLATCH USB port, which is fully
compatible with standard USB cables. When used with SeaLATCH locking USB
cables, the metal thumbscrew provides a secure metal-to-metal connection and
prevents accidental cable disconnection.
Sealevel incorporates SeaLATCH locking USB ports on many USB I/O devices.
Accidental cable disconnection is the most common point of failure with USB
industrial I/O devices and SeaLATCH cables and connectors prevents that while
being fully compatible with standard USB cables.
The image below shows the 2123 secured with the included SeaLATCH cable.
