SHOT TIMER INSTALLATION

This part of the manual describes the mechanical and electrical installation of the shot timer.

One of the items listed below must be purchased in order to complete the installation:

• Control cable (length dependent upon installation site layout)
• ScoreLink 200 RF Modem System (a transmitter and two receivers)

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. The shot timer can be mounted by using either the side or the rear cabinet mounting points.

Rear Mounting Method This shot timer can be mounted in front of a single pole. The mounting points are located at the top and bottom edges of the rear side of the cabinet. Figure 1 shows the mounting points located on the rear of the shot timer.

Two sets of mounting hardware are provided for mounting the model 2160 to a pole. The mounting hardware will accommodate poles up to 7 inches outer diameter. A single set of mounting hardware consists of an aluminum angle bracket, two threaded rods, two washers, and two nuts. Figure 2 shows an overhead cross section view and a side cross section view of the shot timer attached to a pole at a mounting point. A steel bar is riveted inside the scoreboard’s aluminum extrusion frame. The bar has two tapped holes. The threaded rods screw into these tapped holes. The washers and nuts are used to clamp the aluminum angle bracket against the steel post and hold the scoreboard in place.

igure 2 Rear Mounting Method

The following steps describe how to mount the scoreboard on the posts: 1.Screw the threaded rods into the tapped holes on the rear of the shot timer. 2.Raise the shot timer into place at the pole. 3.Place a steel angle bracket over the threaded rods at the top mounting point. 4.Place a washer over each threaded rod. 5.Screw the nuts onto the threaded rods so that the bracket is loosely held in place. 6.Repeat steps 3 - 6 at the bottom mounting point. 7.Tighten the nuts to clamp the shot timer in place on the posts.

Side Mounting Method 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 3 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 2160: 40 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. Figure 4 shows the electrical connection points on the scoreboard.

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 2160 shot timer is compatible with Electro-Mech Scoreboard Company scoreboard models that operate with a control console programmed with the B62C software. The program name appears briefly on the control console LCD display after the operator presses the [NEW GAME], [1], [ENTER] key sequence. If the customer has a scoreboard that operates with this control console, the model 2160 shot timer can be operated with the same control console. If the customer’s control console has a different software program, contact Electro-Mech Scoreboard Co. to determine if their scoreboard can operate with a B62C control console.

If the customer is operating a scoreboard with the same control console as the shot timer, 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) 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 scoreboard to the model 2160 shot timer, each end of the control cable has a ¼” stereo plug attached. When connecting between the control console and the model 2160 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 5 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 6 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.

1/4" STEREO JACK

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 or ScoreLink 200 Transmitter. 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. 4.Plug the shot clock hand held remote into the RJ45 jack mounted on the control console back plate labeled DGT/SC Hand held.

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.
