ELECTRICAL CONNECTIONSThis scoreboard was designed to make the electrical connections as easy as possible. These connections include connecting each scoreboard cabinet to a power source, installing the control cable, daisychaining the serial data lines, and connecting the control console. Figure 1 shows the electrical connection points on the scoreboard. We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of your scoreboard.
Each scoreboard cabinet requires 120 VAC 1 amp service. Each scoreboard cabinet has a 6 foot attached power cord which can be plugged into a NEMA 5-15R receptacle.
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. If you have purchased this option, disregard the next section of this manual. Refer to the SCORELINK 200 RF MODEM SET OWNER’S HANDBOOK for installation instructions. Installing The Control Cable The control cable connects the scoreboard to the control console. A small junction box with a stereo jack mounted on the face plate is attached to the control cable at the point of operation of the scoreboard. A stereo plug is attached to the scoreboard end of the control cable. The 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 and stereo plug attached to the control cable. Some customers prefer to attach them after the cable is installed. Those customers must match their stereo jack to one of the stereo jacks in figure 2 in order to make the proper connections. These connections should be soldered.
Attach a stereo plug to the scoreboard end of the cable according to the figure 3.
Insert the stereo plug into the serial data input jack mounted on top of one of the scoreboard cabinets. Daisychaining the Serial Data Lines Plug one end of a 25 foot extension cable (a cable with stereo plugs attached to each end) into the serial data output jack of the same cabinet. Plug the other end into the serial data input jack of the next scoreboard cabinet to the right of the first cabinet. Connect the next two cabinets in the same manner using two of the remaining extension cables. Connecting The Control Console The control console is connected to the junction box via the extension cable. This extra length of cable allows the scoreboard operator some mobility and the ability to store the control console after the game. The control console requires a 120 VAC 1/2 A power source. The power cord can be plugged into a NEMA 5-15R receptacle. 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.
Installation of Two or More Scoreboards at the Same Site It is possible to operate up to four scoreboards from the same console. Install a control cable line in the same manner as described previously for each additional scoreboard. Connect the additional control cable lines with extension cables to the control console. Never splice the control cables together or connect them to the same junction box. Goal Lights Installation A set of goal lights is an accessory that can be used with this scoreboard. Mount the goal lights 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.
