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

installation:

• Hardware to attach the shot timer to the wall or basketball goal.
• 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 shot timer on the wall or basketball goal. Two 3/8” bolts and two washers are provided for each unit. The bolts and washers can be used to attach the shot timer to the customer’s mounting hardware. There are two tapped holes are located on each side of the cabinet which accept the bolts. Figure 1 shows the mounting points located on one side of the shot timer. Identically spaced holes are located on the opposite side of the shot timer. Be sure to mount the shot timer close enough to a wall receptacle so that you can plug in the 6 ft. power cord.

ELECTRICAL INSTALLATION

We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the shot timer. These connections include connecting the shot timer to a power source, installing the ScoreLink 200 or the control cable, and connecting the control console.

Power Connection The shot timer requires 120 VAC service at the shot timer to operate properly. Maximum power consumption of Model 2170: 60 Watts. The shot timer 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 shot timer can be turned off without turning off other electrical devices in the facility.

ScoreLink 200 The ScoreLink 200 RF MODEM SYSTEM is intended to eliminate the control cable between the shot timer and the control console. If you have purchased this option, disregard the next section of this manual. Refer to the SCORELINK 200 RF MODEM SYSTEM OWNER’S HANDBOOK for installation instructions.

Control Cable Installation The model 2170 shot timer is compatible with Electro-Mech Scoreboard Company scoreboard models MP-259, MP-269, MP-259/220, MP-269/220, MP-259/220-4S, MP- 269/220-4S, 2350, 2370, 2550, 2557, 2570, 2650, 2655, 2770, 2350-4, 2650-4, and 2655- 4. If the customer has one of these model scoreboards, the model 2170 shot timer can be operated with the same control console. If the customer does not have one of these models, the model 2170 shot timer must be operated with its own control console. If the customer has one of the models listed above, he can install the control cable from the ¼” stereo jack mounted on the top of the shot timer to either the shot timer output jack located on the right side of the scoreboard (serial data output jack located on the top of models 2350-4, 2650-4, and 2655-4) listed above or to the control console. A connection to the control console is preferred.

When connecting between the shot timer output jack of the of the listed scoreboards to the model 2170 shot timer, each end of the control cable has a ¼” stereo plug attached. When connecting between the control console and the model 2170 shot timer, the cable end that attaches to the scoreboard has a ¼” stereo plug attached and the other end has a small metal junction box with a ¼” stereo jack mounted on the face plate. The junction box should be securely mounted within 10 feet of the control console point of operation. A 10 ft. cable with ¼” stereo plugs attached to each end (called the extension cable) is provided to make the connection from the junction box the control console.

Most customers order the control cable with the proper connectors attached to each end when ordering the shot timer. Some customers prefer to attach the connectors after the cable is installed. The instructions below describe how to attach these connectors. All connections should be soldered. Splicing the cable is not recommended. Figure 2 shows the connection points to solder the ¼” stereo plug to the control cable. Unscrew the stereo plug cover from the plug body to expose the contact pins. Figure 3 shows the connection points to solder the control cable to the rear of ¼” stereo jack mounted on the face plate of the junction box.
