D/3 USB Keyboard

The D/3® USB Keyboard is an environmentally hardened operator’s keyboard with keys dedicat- ed to process control functions. It communicates at 12 mbps via an available USB 1.0/2.0 port on an OCM, DCM or CDCM.

The D/3 Keyboard contains an audible alarm horn with an adjustable volume control and an alarm relay consisting of a single set of Form C contacts.

D/3 control and display functions can be pro- tected by limiting access to them. To access a protected function, the user must have either a master key to operate the key lock in the D/3 Keyboard or a password and a Console-Enabling Index, CEI. The master key bypasses both the passwords and CEIs to access all protected func- tions.

The D/3 USB Keyboard functions in parallel with a standard QWERTY keyboard. When connected and configured either keyboard may be used.

Drivers and virtual communication port software for Windows 2000, XP, Vista, and Server 2003 are included on the D/3 Keyboard installation CD.

The D/3 Keyboard case is made of steel. The key- pad is a one piece rubber overlay that is sealed to the case making the top impervious to dirt or liquid spills and easy to clean. The standard case has openings in the rear near the connectors;

however, a wash down version of the keyboard is available by special order.

Power for the keyboard functions is provided from the USB connection. The universal 12 VDC power supply (included) is only required when the audible horn or Form C contacts are utilized.

Dedicated Keys

The D/3 USB Keyboard simplifies operator tasks by providing dedicated keys, grouped into a logi- cal arrangement for operators, for selection and process control.

There are 16 quick-select keys which are used to select faceplates and parameters from vari- ous OCM displays. Six keys dedicated to alarms are used to acknowledge alarms, silence audible alarms, and review alarms. Ten display function keys perform general operations for viewing and editing of displays. Eight sequence logic keys are used for interacting with units, recipes, and mes- sages. Five continuous control keys allow direct access for changing setpoints, outputs, and other functions. Finally, four keys provide functions for modifying parameters and four keys are used to ramp values.

See Operator Console User’s Guide for additional information about the D/3 Keyboard functions.
