1.4 HIGH DENSITY FLASHER UNIT (HDFU)
The HDSP-FU (
iPack
®
2202) provides the CMUip-2212 with voltage and current
measurements from each installed HDFU flasher unit. Each HDFU has the capability to
measure and report field terminal voltages and load currents for two channels of two
outputs per channel. The HDFU is configured by its Output Assembly address. For further
information concerning the HDFU, see the Eberle Design
iPack

HDSP-FU Operations
Manual
(
pn 888-2202-001).
1.5 CMUIP-2212 PROGRAMMING
The CMUip-2212 is individually configured using a removable nonvolatile memory device
called a Datakey
tm
(Datakey is a registered trademark of Datakey Electronics, Inc.). The
Datakey replaces the mechanical jumper or diode based program card used in
conventional signal monitors and provides an electronic method of programming the CMU-
2212. The Datakey contains a nonvolatile prom device that is read by the CMU-2212. The
Datakey itself is programmed by a separate programming device using a Personal
Computer program such as the Eberle Design MonitorKey product. See the Eberle Design
MonitorKey Operations Manual
(pn 888-1212-001) for further details.
1.6 DETAILED CMU STATUS
1.6.1 ECCOM SOFTWARE INTERFACE
The front panel display of the CMUip-2212 provides limited operational status. Detailed
status is obtained through the front panel Ethernet port (CMUip-2212) using Eberle Design
ECcom
Signal Monitor Communications software running on a personal computer. The
ECcom software provides access to real time monitor data such as current field signal
status, field terminal voltages, cabinet control voltages, channel load current status,
temperature, and fault status. Historical event logs and signal sequence logs are also
provided. See the
EDI ECcom Operation Manual
(pn 888-1000-001) for further details.
The
ECcom
Signal Monitor Communications software can be obtained from the Eberle
Design web site at www.EDItraffic.com.
1.6.2 AUXILIARY DISPLAY UNIT
The Eberle Design
Auxiliary Display Unit
(ADU) is a display module that provides an
enhanced user interface and SmartMonitor
®
technology for the ATCC Cabinet Monitor Unit
(CMU-2212) system. The
Auxiliary Display Unit
is intended to mount into a 1U space of the
19 inch rack of an ITS Cabinet. The ADU communicates with the CMUip-2212 via Serial
Bus #3. See the
ADU Operation Manual
(pn 888-0217-001) for details.
- WARNING -
The ATC must verify that all channels being driven by a Serial Interface Unit
(SIU) are being monitored by an enabled HDSP, and that each HDSP is
enabled by the programming in the CMU datakey.
Failure to provide this check may result in unmonitored load switch outputs.
This could occur as a result of improper configuration of the cabinet, improper
address assignment for one or more HDSP units, improper address assignment
for one or more SIU units, or improper programming of the ATC.
