DESCRIPTION

The EDACS Site Controller is made up of the SiteController cabinet, the Site Controller computer, and all ofthe standard and optional supporting equipment that getsmounted in the Site Controller cabinet. The standardarrangement for a fully-equipped EDACS Site Controller isshown in Figure 1. The actual arrangement may varysomewhat, depending upon which options or specialcustomer requirements are supplied. Blank panels areprovided in place of non-supplied optional front-mountedequipment. The Auxiliary AC Power Strip is used in placeof the AC Relay Panel when the Guardog option is notsupplied. The 230V, 50 Hz version of the Main AC PowerStrip is mounted in a different position than the 120V, 60 Hzversion. For more information, see Interconnection Diagram16 or Interconnection Diagram 17 at the end of this manual.

The EDACS Site Controller supports up to 20 channelsfor a Level 1 EDACS system, or up to 24 channels for aVoted (non-Simulcast) or Simulcast (Voted or non-Voted)system. In a Level 1 system, the EDACS Site Controller islocated at the site with the EDACS Repeaters. In a Voted(non-Simulcast) system, the EDACS Site Controller islocated at the Main Site. In a Simulcast system, the EDACSSite Controller is located at the Control Point.

STANDARD EQUIPMENT

The standard EDACS Site Controller consists of thefollowing standard equipment:

• Cabinet

• Exhaust Fan

• Main AC Power Strip

• Auxiliary AC Power Strip

• EDACS Interface Panels

• Downlink GETC

• Site Controller

• System Manager Modem

Site Controller Computer

The Site Controller is a 32-port DEC computer withapplication software to provide system-level supervision forthe EDACS equipment in a single or multisite EDACSsystem. Earlier models are referred to as PDP-11 models.Later models are referred to as VAX models. Earlier PDP-11 models and later VAX models (except the current VAXmodel) are identified by the use of EMULEX or DILOGpanels as connection points to the Site Controller. Thecurrent VAX model is identified by the 8-pin modularconnectors mounted directly in the back panel of the SiteController. For connections to the Site Controller, seeInterconnection Diagram 1 at the end of this manual.

System Manager Modem

The modem for the data link to the System Managerprovides the interface at the Site Controller end when avoice-frequency data link is used between the SiteController and the System Manager. For connections to theSystem Manager, see Interconnection Diagram 4 at the endof this manual.

DC Power Supply

The DC Power Supply provides regulated +13.8 VDCfor the standard Downlink GETC and the optional PowerMonitor Unit, Redundant Downlink GETC, Alarm andControl Unit, Test Unit, and Guardog (Reset Unit and ACRelay Panel).

INSTALLATION

Each step of the installation consists of one or moreinformation paragraphs followed by one or more actionitems (identified by the ❏ symbol so it can be checked offwhen completed). Skip steps for equipment not supplied.

CABINET

The cabinet or open rack has four holes in the bottomfor 1/2-inch bolts or lag screws to fasten the cabinet or openrack directly to the floor, or to a raised platform (which isitself secured directly to the floor). An open rack also comeswith two holes in each side (one near the top; one near thebottom) for 3/8-inch bolts for securing the rack to anotherrack on either side.

❏ Secure the Site Controller cabinet (or open rack) tothe floor or the raised platform using four 1/2-inch bolts orlag screws. If the EDACS Site Controller is mounted in anopen rack, also fasten the rack to any adjoining rack usingtwo 3/8-inch bolts.

PROTECTIVE GROUND

A protective ground wire must connect the SiteController cabinet to the same single-point ground that isused by all equipment in the room. Use annealed copperwire with a cross section no smaller than that of #2 AWGwire and no longer than 25 feet. Solid wire is better thanstranded wire. Use as straight and direct a route as practical.If bends are unavoidable, they should have no less than a 12-inch bending radius. Do not run the wire through metalconduit.

The Site Controller cabinet is equipped with a copperground bus running vertically along the left side rail, asviewed from the back of the cabinet. The protective groundwire can be run through the top of the cabinet and connectedto the upper end of this ground bus, or run through thebottom of the cabinet and connected to the bottom end ofthis ground bus.

❏ Connect a protective ground wire from the groundbus in the Site Controller cabinet, to the single-point groundthat is used by all equipment in the room.

AC POWER

The AC power for the Site Controller cabinet must besupplied through a separate circuit breaker. Use a 20-ampcircuit breaker for 120 V, 60 HZ, or a 10-amp circuitbreaker for 230 V, 50 Hz. The outlet for this circuit must beplaced within reach of the Site Controller cabinet’s powercord.

The Site Controller cabinet is equipped with an ACpower cord terminated with a NEMA 5-15 type plug for120V, 60 Hz, or a CEE 7/7 type plug for 230V, 50 Hz. TheAC power cord may be routed through the top or bottom ofthe cabinet. The AC power cord is approximately 15 feetlong from the point where it is fastened to a power strip nearthe bottom of the cabinet. Therefore, routing the cordthrough the top of the cabinet will make it appear shorter bythe approximate height of the cabinet.

❏ Turn off the AC circuit breaker for the EDACS SiteController cabinet. Plug the EDACS Site Controller’s ACpower cord into the AC outlet provided for the SiteController cabinet. Do not turn the AC circuit breaker on.

INTERFACE PANEL #1

The EDACS Site Controller is equipped with twoEDACS Interface Panels mounted in the back of the cabinetnear the top. The upper panel is referred to as EDACSInterface Panel #1 (part number 19D904009G12) and isshown in Figure 2.

Power Sensor Module

If the EDACS Site Controller is equipped with a PowerMonitor Unit, the upper interface panel is equipped with a“POWER SENSOR” module. The Power Sensor moduleprovides the connection points between the transmitterpower sensor circuits from the repeater cabinets and thePower Monitor Unit in the Site Controller cabinet. ThePower Sensor module also provides the connection pointsfor the antenna power sensor circuits between each antennapower sensor in an RF cabinet and the Power Monitor Unitin the Site Controller cabinet.

The 19C852632G1 Power Sensor module is used withthe present DB8860-based Power Monitor Unit as shown inInterconnection Diagram 11 at the end of this manual.

Transmitter Circuits

A transmitter power sensor circuit consists of a powersensor at the output of a transmitter, the cable connecting itto the Power Sensor module in the repeater cabinet, and aseries of daisy-chained cables between the Power Sensormodules in neighboring repeater cabinets and finally the SiteController cabinet. The transmitter power sensor circuits forchannels 1 through 12 are carried by one daisy chain ofcables. The transmitter power sensor circuits for channels 10through 20 are carried by another daisy chain of cables. Thetransmitter power sensor circuits for channels 11 and 12 areincluded in both daisy chains to support configurations ofeither 2, 3, or 4 channels per cabinet.

All unused transmitter power sensor circuits must begrounded. One jumper board, with grounding jumpers, isprovided for installation at the end of each of the twopossible daisy chains. When no second daisy chain is usedthe second jumper board is installed in the Power Sensormodule in the Site Controller cabinet. These 19C852379G1jumper boards are usually found wrapped in plastic andtaped to the top of the Site Controller computer.

All unused transmitter power sensor circuits mustbe grounded (jumper present on jumper board).

The power sensor circuits for channels 11 and 12each have two jumpers (one on each jumperboard). Both jumpers must be removed if a powersensor is connected to one of these circuits.

NOTE

❏ Connect a 25-pair cable from J1 on the PowerSensor module in the Site Controller cabinet, to J14 on thePower Sensor module in the first repeater cabinet of the firstgroup of channels (repeater cabinet containing channel 1).

❏ Follow the string of 25-pair cables connecting J15on one Power Sensor module, to J14 on the next until youreach an empty J15. Plug the first 19C852379G1 jumperboard into this empty J15.

❏ Remove the jumper for each channel which isequipped with a power sensor (see interconnection diagramat the end of this manual). If channel 11 or 12 is equipped
