General
1.1 OVERVIEW
The Eberle Design Auxiliary Display Unit (ADU) is a display module that provides an
enhanced user interfac e for th e ITS C abinet M oni t or U n it ( CMU-212) system. T h e Auxiliary
Dis p lay Unit is i ntend ed to mount int o a 1U sp ac e of th e 19 inch r ack of an ITS C abinet.
The Auxiliary Display Unit meets with or exceeds all specifications outlined in the
ASHTO/ITE/NEMA Intel ligent Tr ansport ation Sy stem (IT S) Standar d Specif ication f or
Roadside Cabinets Version 01.02.17b document.
1.2 DISPLAYS
The Aux iliary Dis play Un it provi des a Red, Yellow, and Green st atus LED indicator along
with a Blu e LED indic ator f or fault st atus, f or each of the thir ty tw o chann els supp orted b y
the CMU-212. This LED Channel Status display provides a full view of the intersection
status.
The Aux ilia ry Disp lay Un it al s o provid es a Liqui d Cr yst al (LCD ) b ase d men u dr iven dis play
that provid es det ailed status inf ormati on fr om the CMU-212 along with an interface to the
EDI SmartMonitor® technology.
For further information on the ITS Cabinet Monitor Unit (CMU-212), CMU-212 monitor
functions, and CMU D ata Key parameters ref er to the E berle Design CMU-212 Cabinet
Monitor Unit Operations Manual (pn 888-0212-001).
1.3 CONTEXT SENSITIVE HELP SYSTEM
The built-in Help s ystem provid es operati onal guidanc e as well as trouble sh ooting advic e
to both the novice and expert technician. The front panel HELP button presents the
requested information on the main LCD depending on the display page and context
currently selected.
1.4 SMARTMONITOR
®
DI AGN OS TIC WI ZAR D
The built-in Di agnostic W izard (s ee S ect ion 4) is an integral part of the Help System th at
provides detailed diagnostic information regarding the fault being analyzed. The Wizard
provides a concise view of the signal states involved in the fault, pinpoints faulty signal
inputs, and provides guidance on how the technician should isolate the cause of the
malfunction.
The CMU-212 monitor must be programmed with a firmware version that
supports the operation of the Auxiliary Display Unit (ADU). Consult the
factory for the firmware version information for the installed CMU-212 model.

Front Panel Description
2.1 DISPLAYS
2.1.1 CHANNEL STATUS DISPLAY
Thirt y two Red , Yellow, and Gr een LED indicators are provided by the Auxiliary Display
Unit to display the com plete inters ection st atus of the field signal inputs t o the CMU-212
monitor. If the monitor is oper ating nor mall y without a fault con diti on presen t, the cu rrentl y
active RYG field input signal states will be displayed.
When th e CMU-212 monitor is in the fault mode, all channels that were involved in the fault
will be indicated by the Blue LED indicators.
2.1.2 MAIN S TATUS DISPL AY
The Mai n Stat us Dis play (LCD) of t h e A ux il iar y Dis p la y U n it is us ed t o displa y the cur rent

4.1 LAUNCHING THE DIAGNOSTIC WIZARD
The Di agnost ic W izard is aut omatic ally in voked when the CMU-212 monit or is in th e fault
mode and th e H E LP bu tton is press ed w hil e the Main Status dis play is at the top level. It is
also automaticall y i n vok ed wh en th e Auxiliary Display Unit is in the Previous Fail (PF) event
log display mode and the HELP button is pressed.
4.2 DIAGNOSTIC WIZARD STEPS
Press in g the H ELP b utton or t he N E XT b utton w il l sequ ence th e disp l ay thr oug h t hi s seri es
of steps. At any point the EXIT button will return the display back to the normal display
mode.
4.2.1 CONCISE DISPLAY STEP
The first step of the Diagnostic Wizard provides a simple definition of the fault type
detect ed. It als o filters th e Channel St atus dis play to a c oncise vi ew of only th e ch annels
ac tually invo lv ed in the fault.
Press the HELP or NEXT button to proceed to the next Diagnostic Wizard step.
4.2.2 FAULTY SIGNAL IDENTIFICATION STEP
The next step(s) pinpoint known faulty signals. This function relies on the proper
progr am mi ng of t h e Fi eld Ch ec k En able p ar am et er s i n the C MU -2 12 Data K ey. This s tep is
the heart of the Diagnos tic W izard. It identif ies first whether the fault condition was caus ed
by t he Controller Unit or by a malf unction of the load b ay or field wi ring and loads. If th e
malfunction was caus ed by a malfunction of the load bay or field wiring and loads, the
“fault y” in puts of each ch an nel ar e direc tly identified along wit h t h e proper st ate.
Press the HELP or NEXT button to proceed to the next Diagnostic Wizard step.
4.2.3 TROUBLE SHOOTING TIPS STEP
The last step off ers the tech nician s everal sugg estions to investigate f or th e cau se of t he
malfunction.
If Field Check is not enabled f or a signal that is part of the concise display fault
status then the D iagnostic Wizard wil l identify the input(s) as “not Field Checked”.
The f ull benefit of the Diagnostic W izard will not be obtained unless the CMU-212
has been fully progr am m ed w ith the F i eld Ch ec k En able parameters c orrec t l y s et.
