IWK keyboards can be used for remote
access of IWP series power board functions
by displaying functional parameters and the
operating temperature.
The Split version of the Wide device consists
of two units:
• an IWK keyboard available in several
sizes*
• an IWP power module. The IWK keyboard
is connected to the IWP power module via a
“powered” serial connection.
*Different IWK keyboard models are
available: this technical data sheet
describes the Eliwell standard 32x74 IWK
keyboard. For information on other key-
boards, refer to the relevant technical
data sheets.
