The ET-DSELB can be used to program both ETERNA slide and NEXT swing operators. It is easily identified by its black colour and GREEN LEAF symbol in the upper right corner.

This digital programmer is an essential requirement for the installer to configure the operator, perform its set-up, change its functions/parameters, carry out system diagnostics and access the event memory.

It can also be utilised by the end user to switch between operating modes (e.g. one-way, two-way, hold open), and is therefore password protected to stop unwanted persons from tampering with the chosen settings.
