ScoreLink 200 RF Modem System

Items not provided by Electro-Mech Scoreboard Company that are necessary for

installation:

Wall fasteners
A grounded NEMA 5-15R 120 VAC receptacle for the control console at the scorekeeper’s table.

Electro-Mech Scoreboard Company performs installations in some areas. In other areas, we can help you contact an independent installer. In areas in which installation service is not available from Electro-Mech Scoreboard Company, we will make every effort to answer your installation questions. Qualified personnel should perform the scoreboard installation. Consult national and local codes before installation.

MECHANICAL INSTALLATION

The mechanical installation includes mounting the scoreboard on the wall and attaching the optional bottom sponsor panel (if purchased) to the scoreboard.

Mounting the Scoreboard The following steps describe how to mount the scoreboard on the wall:

1.There are two hanger brackets attached to the scoreboard near the top of the cabinet on the rear side. They may have been rotated down to facilitate shipping. Rotate the hanger brackets so that they protrude past the top of the scoreboard and tighten the bolts. 2.Lift the scoreboard to the desired location. There are two eyebolts mounted at the top of the cabinet that can be used to lift the scoreboard into place. Be sure to mount the center of the scoreboard close enough to the wall receptacle so that you can plug in the 6 ft. power cord. 3.Insert lag bolts or other suitable fasteners through the hanger brackets and fasten the scoreboard to the wall. Figure 1 shows the mounting point locations for model 2770.

Attaching the Optional Bottom Sponsor Panel Two attachment plates, four bolts, and four washers are provided to attach the sponsor panel to the bottom of the scoreboard. The attachment points are located on the sides of the scoreboard and sponsor panel cabinets. The following steps describe how to attach the sponsor panel to the scoreboard:

1.Raise the sponsor panel to the bottom of the scoreboard. 2.Fasten an attachment plate to the right side of the scoreboard and sponsor panel using the provided washers and bolts as shown in figure 2. 3.Fasten the other attachment plate to the left side of the scoreboard and sponsor panel in the same manner.

Figure 2 2770 with Bottom Sponsor Panel Attached

ELECTRICAL INSTALLATION

We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the scoreboard. These connections include connecting the scoreboard to a power source, installing the ScoreLink 200 or the control cable, and connecting the control console. The installation of goal lights and multiple scoreboards is also described in this section.

Power Connection The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model 2770: 120 Watts. The scoreboard has a 6 ft. attached power cord located at the top of the cabinet. Plug the power cord into a grounded NEMA 5-15R receptacle. The receptacle should be controlled by a separate circuit breaker so that the scoreboard can be turned off without turning off other electrical devices in the facility. Figure 3 shows the electrical connection points on the scoreboard.

ScoreLink 200 The SCORELINK 200 RF MODEM SET is intended to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard MM and MP series scoreboards as well as all LED scoreboards. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the SCORELINK 200 RF MODEM SET OWNER’S HANDBOOK for installation instructions.

Control Cable Installation The control cable connects the scoreboard to the control console. A small junction box with a ¼” stereo jack mounted on the face plate is attached to the control cable at the point of operation of the scoreboard. This junction box should be securely mounted within ten feet of the rear of the control console. Most customers order the control cable with the junction box attached. Some customers prefer to attach the junction box after the cable is installed. Those customers must solder the control cable to the ¼” stereo jack. Figure 4 shows the control cable wire connection points on the rear of the ¼” stereo jack.

Figure 4 ¼” Stereo Jack Wiring Diagram — PIN 1 - BLACK WIRE PIN 2 - RED WIRE PIN 3 - SHIELD WIRE — Figure 4 ¼” Stereo Jack Wiring Diagram Labelled: PIN 1 - BLACK WIRE PIN 2 - RED WIRE PIN 3 - SHIELD WIRE

A ¼” stereo plug is attached to the scoreboard end of the control cable. It is inserted into the ¼” stereo jack mounted on top of the scoreboard. Most customers order the control cable with the ¼” stereo plug attached. Some customers prefer to attach it after the cable is installed. Those customers must solder the ¼” stereo plug to the cable according to the figure 5. Unscrew the stereo plug cover from the plug body to expose the contact pins.

Figure 5 ¼” Stereo Plug Wiring Diagram — STEREO PLUG COVER, PIN 3 - SHIELD WIRE, PIN 2 - RED WIRE, PIN 1 - BLACK WIRE — Figure 5 ¼” Stereo Plug Wiring Diagram Labelled: STEREO PLUG COVER · PIN 3 - SHIELD WIRE · PIN 2 - RED WIRE · PIN 1 - BLACK WIRE

Control Console Connections The 10 ft. extension cable has two molded ¼” stereo plugs attached to it. It is used to connect the control console to the junction box. The following steps describe how to connect the control console:

1.Plug one end of the extension cable into the ¼” stereo jack on the junction box or the ScoreLink 200 Transmitter, if purchased. 2.Plug the other end into one of the four ¼” stereo jacks mounted on the control console back plate. 3.Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle.

Control Console Safety Warning This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding- type plug.

Goal Lights Installation This scoreboard can control a set of goal lights. The following steps describe how to install a goal light:

1. 2. 3. 4.

Mount the goal light in the desired location. Splice wires (not provided) to the two wire leads of the goal light. Attach a polarized plug to the other end of the wires. Insert the plug into the goal light receptacle on the right side of the scoreboard cabinet. The goal light receptacle is protected by a 1 amp fuse. Do not insert bulbs greater than 40 watts in the goal lights.

Installation of Two or More Scoreboards at the Same Site It is possible to operate multiple scoreboards or shot timers from the same console. Either install a control cable between each unit and the control console or install a ScoreLink 200 Transmitter at the control console and a ScoreLink Receiver at each scoreboard or shot timer. Additional scoreboards and shot timers can be controlled by connecting a control cable from the serial data output ¼” stereo jack on the right side of an installed scoreboard cabinet (figure 3) to the serial data input ¼” stereo jack on the top of the additional scoreboard or shot timers. Attach ¼” stereo plugs on each end of these cables according to figure 5. Never splice the control cables together or connect them to the same junction box. Each scoreboard will need to be connected to 120 VAC service.

SCOREBOARD STARTUP

1.Place the circuit breaker for the scoreboard in the ON position. 2.Plug one end of the extension cable into the ¼” stereo jack on the junction box or the ScoreLink 200 Transmitter, if purchased. 3.Plug the other end into the ¼” stereo jack mounted on the control console back plate. 4.Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle. 5. If a ScoreLink 200 RF MODEM SYSTEM is installed with this scoreboard, plug the wall mount DC power supply into a grounded NEMA 5-15R 120 VAC receptacle and the male plug on the end of the attached cable into the Power jack on the Transmitter.

1.Remove the machine screws that fasten the mask to the face of the scoreboard. Caution: Support the mask with your hand before removing the last screw. The ribbon cable that connects to the rear of the circuit board is not designed to support the weight of the assembly. 2.Disconnect the ribbon cable from the rear of the circuit board. Caution: Do not let the cable hang outside of the scoreboard. It is easily cut by sharp metal edges. Damage to the ribbon cable may create short circuit paths that will damage the LDM1 LED driver module. 3.Place the assembly on a flat surface and remove the 6-32 kep lock nuts that hold the circuit board in place. 4.Remove the circuit board. 5.Align the mounting holes in the circuit board with the threaded studs on the mask and install the replacement digit on the mask. 6.Plug the ribbon cable onto the header on the back of the circuit board. Refer to figure 9 in order to plug the ribbon cable IDC connector onto the circuit board in the proper orientation.

RIBBON CABLE IDC SOCKET

7.There are two circuit boards that may be used for the BONUS indicators. One circuit board has two headers and may be used for either BONUS 1 or BONUS 2. As seen in figure 10, inserting the ribbon cable IDC socket on the top header makes the circuit board operate as BONUS 1. Inserting the ribbon cable IDC socket on the bottom header makes the circuit operate as BONUS 2. The other circuit board has one header and may only be used for BONUS 1.

RIBBON CABLE IDC SOCKET

Horn Replacement 1.Remove the machine screws that fasten the mask to the face of the scoreboard. 2.Pull the horn assembly out of the scoreboard and cut the two wires leading up to the rear of the horn assembly. 3.Splice the new horn assembly wires to the two wires inside the scoreboard. 4.Install the horn assembly and fasten it to the scoreboard face using the machine screws.
