User Inputs
The user input(s) is a feature allowing a third-party device to interface with the 3300 digital clock model
via a dry contact closure for the purpose of sending a command to the clock. For example, upon receiving
a contact closure, the clock can initiate a count up, initiate a countdown, flash the time, and/or can trigger
additional commands.
Programming the clock as for which command to be triggered upon receiving the user input is done by
using the USB Programming Cable and the SBD Config software. Detailed instructions for programming
the clock can be found in this manual in the “
” section.
For utilizing the user input feature, use a dry contact closure between any of the two lines shown above
to activate one of the numbered user inputs. This input is a dry contact closure, which means that
the
user should not be providing external power on either of the lines leading from the relay to
the clock
. The dry contact closure only needs to complete the circuit when activated and can be a simple
switch or button.
To configure what a given input does to the clock when activated, refer to the section of this manual
labeled “
