3.1
INTRODUCTION
The operation of the Model 1150A VOR is controlled by a system of local and remote controls and status displays
that provides the following general capabilities:
1. Control of operational parameters and comprehensive display of operational status through the use of user
friendly Windows XP
™
or VISTA
™
based PMDT application running on a standard PC or notebook
computer.
2. Control and display of equipment operation in the airport maintenance room and tower cab.
3. Remote control and status via modem and dial-up telephone line with the same displays and control menus
as are used with local control.
3.2
REMOTE CONTROL STATUS UNIT (RCSU)
The RCSU provides summary level control and status of the VOR equipment. The RCSU is usually located in the
airport equipment maintenance room. The controls and indicators on this panel are described in the RCSU manual
(572238-0001or 572240-0001) specific to this equipment.
3.3
REMOTE STATUS UNIT (RSU)
The RSU displays the summary level status for one pair of opposing approaches and an additional VOR/DME site,
but on a smaller panel than the RCSU that is suitable for installation in a console in the tower cab. The controls and
indicators on this panel are described in the RCSU manual (572238-0001or 572240-0001) specific to this
equipment.
3.4
REMOTE STATUS DISPLAY UNIT (RSDU)
The RSDU displays the same summary level status as the RCSU, on either a notebook pc, desktop LCD, or a touch-
screen controlled display installed in the tower cab or various other locations. The controls and indicators on this
display are described in the 2238 RCSU manual (572238-0001) specific to this equipment.
3.5
PORTABLE MAINTENANCE DATA TERMINAL (PMDT)
The PMDT system is comprised of a Microsoft Windows-based desktop or notebook PC and the PMDT control and
monitoring software. The PMDT can be used in differing applications including:
1. Local control and status of VOR equipment in the equipment shelter. In this application the PMDT
connects directly to the Remote Maintenance Subsystem (RMS) interface on the front of the equipment
cabinet.
2. Remote Maintenance Monitor (RMM). The same software and hardware used in the shelter for direct
control of the equipment can be used remotely to control and monitor the equipment.
The PMDT software allows the operator to easily select control parameters and monitor thresholds for display and
change, and to select operation and status parameters for display. The operator can control the operational state of
the equipment for maintenance purposes.

3.5.1.1 Connecting the PMDT
When connecting directly to the VOR, the PMDT PC connects to the J1 PMDT USB port on the front of the RMS
CCA using a standard USB A/B cable from one of the PMDT PC’s USB ports. This USB cable (SELEX-SI
#950915-0000) is supplied with the PMDT PC.
When the PMDT is used as an RMM, the connection is made by connecting the PMDT’s internal modem to the
TELCO line and using the PMDT software to either call the VOR directly, or call an associated RCSU to establish a
PMDT-Passthru link to the VOR via the RCSU. Alternatively to the modem-based RMM connection, the PMDT
can connect to the RCSU over a standard TCP/IP network link for RMM operations.
