NotaTech Electronic Keyboard D 3 User Manual

D/3® USB Keyboard  
Process Control Functions  
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.  
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.  
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.  
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.  
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.  
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.  
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;  
See Operator Console User’s Guide for additional  
information about the D/3 Keyboard functions.
