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 installing the posts and mounting the scoreboard and the optional sponsor panels (if purchased) to the posts.
Post Installation The scoreboard mounts on two posts. Typically installers will use steel pipes or I-beams. In order to reduce the glare from the sun on the front of the scoreboard, position the posts so that the front of the scoreboard is angled away from the afternoon sun, if possible. The mounting hardware will accommodate posts up to 7 inches outer diameter. Sink the posts in reinforced concrete footings. Figure 1 shows the spacing of the posts for the 3250 scoreboard. The specifications for the posts and concrete footings are dependent upon the expected local wind and soil conditions, the height of the scoreboard from the ground, and the local building codes. Electro-Mech Scoreboard Company assumes no responsibility for the installation of scoreboards by others.
Figure 2 shows the spacing of the posts for a 3250 with an optional top sponsor panel. This panel is a separate unit that mounts on the same posts as the scoreboard.
Three posts are needed for a 3250 with side sponsor panel. Figure 3 shows the spacing of the posts for a 3250 with side sponsor panel. The side sponsor panel is a separate assembly that bolts to the side of the scoreboard.
Mounting The Scoreboard The scoreboard is attached to the posts at four points. Figure 4 shows the location of the mounting points on the rear of the scoreboard.

ELECTRICAL INSTALLATION
We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the scoreboard. These connections include grounding the scoreboard, installing the horn, connecting the scoreboard to a power source, installing the ScoreLink 300 or the control cable, and connecting the control console.
| Ground Connection | ||
|---|---|---|
| The National Electrical Code | requires a scoreboard (electric sign) to be grounded. Grounding the | |
| scoreboard helps the scoreboard electronics operate properly and helps minimize damage if it is struck by | ||
| lightning. Metal posts do | not provide an adequate ground path. The following steps describe how to | |
| ground the scoreboard: | ||
| 1. | Drive one or more 5/8” x 8’ copper clad ground rods in the soil near the scoreboard. | |
| 2. | Connect #6 bare copper wire to the ground rods using 5/8” brass tear drop connectors. | |
| 3. | Remove the rear access panel and the dome plugs on the plate below the access panel. Figure 6 shows | |

Horn Installation The items provided to install the horn are the horn, the weatherproof back box, the mounting bolts, and the mounting bracket. Items which are not provided but are necessary for proper installation are ¾” flexible conduit, a ¾” right angle male conduit connector, a ¾” straight male conduit connector, two wires, and four forked crimp terminals. The electrical requirements for the horn are 0.35 A 120 VAC. The horn assembly is attached to the left side of the scoreboard for models with top sponsor panels. These models have two tapped holes at the mounting point. Other models may have tapped holes on the left side of the scoreboard or have one tapped hole on the top of the scoreboard at the mounting point. Mounting bolts are screwed into the tapped holes at the factory. The following steps describe the assembly and mounting of the horn: 1.Remove the mounting bolts from the scoreboard. 2.Cut a piece of ¾” conduit of sufficient length to reach from the horn mounting point to one of the holes in the plate below the access panel. 3.Attach the ¾” right angle male conduit connector to one end of the conduit and the ¾” straight male conduit connector to the other end. 4.Cut two pieces of wire of approximately 7 feet longer than the conduit. 5.Push the wires through the conduit. 6.The horn mounting bracket has a side mount bracket attached. If the horn is going to be mounted on top of the scoreboard, remove the side mount bracket as seen in figure 8.
7.
7.Push the end of the conduit with the right angle male conduit connector through the 2” diameter hole in mounting bracket. 8.The weatherproof back box has two threaded conduit holes. Screw the provided conduit plug into the hole near the word “TOP” inside the weatherproof back box. 9.Feed the wires through the other back box conduit hole and screw the right angle conduit connector to the back box. 10.Attach the weatherproof back box to the mounting bracket using the provided 8-32 x 1/2” Phillips head machine screws, #8 split-lock washers, and 8-32 hex nuts as shown in figure 9.
11.Remove the horn signal mounting plate from the horn base by loosening the Phillips head screw on the base as seen in figure 10.
12.The word “TOP” is stamped on the front side of the horn signal mounting plate. Pass the two wires that are inside the back box through the horn signal mounting plate center hole from the rear. 13.Align the horn signal mounting plate with the back box so that the word “TOP” on the horn signal mounting plate and the back box should be oriented in the same direction and the screw hole on the bottom edge of the horn signal mounting plate should be directly over the gap in the back box gasket as seen in figure 11. 14.Fasten the horn signal mounting plate with the four 8-32 x 7/16” machine screws that are provided with the back box.
15.Crimp forked terminals on the ends of the two wires and attach them to the plug receptacle seen in figure 12.
16.Slide the slot on the side of the horn base over the tab on the horn signal mounting plate and tighten the Phillips head screw on the other side of the horn base. 17.Fasten the horn assembly to the scoreboard using the mounting bolts from the scoreboard as seen in figure 13.

Connect the AC-L wire to the left terminal and the AC-N wire to the right terminal.
Power Connection to Scoreboard The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model 3250: 221 Watts. Make sure that power cable is rated for this electrical load. Install the power cable in conduit. Avoid running the power cable in close proximity to the control cable. The following steps describe how to connect the scoreboard to the power source: 1.Feed the power cable through a hole in the plate below the access panel. 2.Crimp fork terminals to the power cable wires. 3.Connect the AC line wire and AC neutral wire to the Main Power terminal block on the junction chassis according to Figure 14.
Install a power disconnect that isolates all current carrying conductors on one of the posts below the scoreboard (not the ground conductor). If a secondary switch is installed near the scorekeeper’s table, it should also isolate these conductors. Place the power disconnect in the OFF position between games to help protect the scoreboard from lightning damage. A power disconnect on the scoreboard post also provides a convenient way of turning the scoreboard off during maintenance or repairs.
ScoreLink 300 The ScoreLink 300 RF MODEM SYSTEM is designed 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 300 RF MODEM SYSTEM OWNER’S HANDBOOK for installation instructions.
Serial Data Output Connections Customers who have purchased a set of delay of game timers can provide one unit with serial data from this scoreboard. This connection is an alternative to providing a delay of game timer with serial data from the control console via the control cable or a ScoreLink 300 RF modem. Do not connect the second delay of game timer to this scoreboard. The following steps describe how to transmit serial data from this scoreboard to one delay of game timer: 1.At the rear of the scoreboard, feed data cable (same type of cable specified for control cable on page 3) through a hole in the plate below the access panel. 2.Crimp fork terminals to the cable wires and the shield. 3.Connect the cable to the terminal block labeled Serial Data Output on the junction chassis according to figure 15.

8.
Reinstall the delay of game timer rear access panel.
Control Cable Installation The control cable connects the scoreboard to the control console. Install the control cable in conduit. If the cable is ever damaged, it is easier and less expensive to replace a cable in conduit. 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 in a clean, dry area 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 17 shows the control cable wire connection points on the rear of the ¼” stereo jack.
1/4" STEREO JACK
The following steps describe how to connect the control cable to the scoreboard: 1.At the rear of the scoreboard, feed the control cable through the left hole in the plate below the access panel. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to the terminal block labeled Control Cable on the junction chassis according to figure 18.

LED Digits Replacement
The LEDs that form digits are soldered on circuit boards mounted behind metal masks. Do not attempt to replace individual LEDs. In case of a malfunction, the entire LED circuit board must be removed. To avoid damage to the LED driver module,always turn off the power to the scoreboard when removing or replacing LED digits. Figure 21 shows the components of an LED digit assembly.
1.
Remove the sheet metal screws that fasten the mask to the face of the scoreboard. Caution: Support the mask 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. 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 LDM12 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. Remove the old circuit board. Align the mounting holes in the new circuit board with the threaded studs on the mask and install the replacement digit on the mask. Plug the ribbon cable onto the header on the back of the circuit board.
