PRODUCT DESCRIPTION

The SCORELINK 300 RF MODEM SYSTEM is an accessory that allows an Electro- Mech Scoreboard Co. MM or MP series control console to send instructions to an Electro-Mech Scoreboard Co. outdoor MM, MP, or LED scoreboard without the connection of a control cable between the console and the scoreboard. The SCORELINK 300 RF MODEM SYSTEM consists of two units: a transmitter and a receiver. The transmitter sends radio frequency signals that contain the console instructions through the air to the receiver. The receiver detects the radio frequency signals and passes the instructions to the scoreboard. The transmitter is designed for indoor use and is installed near the control console. The receiver is packaged for outdoor use and is installed adjacent to the scoreboard. The receiver should be installed within 750 ft. of the transmitter with no line of sight obstructions. Non-metallic obstructions may decrease the range. The transmitter signals can not pass through metal objects.

The SCORELINK 300 RF MODEM SYSTEM consists of a transmitter and a receiver which are factory set to the same channel. There are eight factory set channels available. Contact the factory if the site requirements exceed the eight channel capacity. Multiple scoreboards can be controlled with one control console, one transmitter, and multiple receivers if all units are on the same channel. Additional transmitters and receivers are available for purchase from Electro-Mech Scoreboard Co. Transmitters and receivers with different channel numbers will not work together. Multiple transmitters with identical channel numbers in close proximity may cause interference problems.

While the SCORELINK 300 RF MODEM SYSTEM is intended to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard MM, MP, or LED series scoreboards, it does not replace the need to run power cables to the scoreboard. Disregard the Control Cable Installation section of the scoreboard owner’s manual.

INSTALLATION

Installation of the SCORELINK 300 RF MODEM SYSTEM consists of mounting the receiver at the scoreboard, locating the transmitter at the scorekeeper’s table, and making the proper electrical connections.

Transmitter Installation The preferred method of installation is the transmitter located within direct line of sight of the scoreboard with the top of the transmitter pointing up. Objects between the transmitter and the receiver will tend to decrease the system operating range. The transmitter signal will not pass through metal, so a large metal structure between the transmitter and receiver may prevent the system from working. However, the signal may bounce off metal objects in an indirect path to the receiver and allow the system to work.

The transmitter can be mounted on a window using the provided suction cups or on a wall using screws. It may be possible to operate with the transmitter placed on a flat surface like a table. Figure 1 shows one possible installation inside a press box using the suction cups to attach the transmitter to a window.

A ¼” stereo extension cable is provided to make the connection between the control console and the transmitter. Plug one end of the cable into the ¼” stereo jack (Signal) on the transmitter and plug the other end into one of the ¼” stereo jacks on the rear of the console. The transmitter operates with a DC power cube supply. Plug the male plug into the Power jack on the transmitter and plug the power cube into a standard 115 VAC (NEMA 5-15R) receptacle. The transmitter uses 0.1A of current. Figure 2 shows the transmitter jacks and indicators.

Receiver Installation The receiver should be mounted above (preferred) or below the scoreboard on the post that is closest to the rear access panel. For scoreboards with more than one access panel, refer to the scoreboard owner’s manual to identify the access panel that the control cable would have been connected behind (listed in the section titled Control Cable Installation). The connections from the receiver to the scoreboard will be made behind this access panel. Locate the receiver on the post that is closest to this access panel. The receiver is contained within a weatherproof box. Make sure there are no cracks in the weatherproof box. Clamp the weatherproof box to the post with the provided hardware according to figure 3. Point the weatherproof box hinged cover toward the transmitter location.

Remove the access panel. A section of flexible conduit is attached to the weatherproof box. Two cables extend from the conduit. Run the cables through one of the knockouts below the access panel and fasten the end of the conduit to the scoreboard using the conduit nut. The data cable has three wires and is attached to Control Cable terminal block behind the scoreboard rear access panel. For scoreboards with more than one access panel, refer to the scoreboard owner’s manual for the location of the terminal block. Figure 4 shows the connections to Control Cable terminal block.

The power cable has two wires and is attached to terminal block to which the power cable wires that supply the scoreboard are connected. Refer to figures 5, 6, and 7 to determine the appropriate power connections.

Figure 5 shows the connections to the power terminal block found in our smaller outdoor MM and MP scoreboards.

Figure 6 shows the connections to the power terminal block found in our larger outdoor MM and MP scoreboards.

Figure 7 shows the connections to the main power terminal block inside the outdoor LED scoreboards.

IMPORTANT: After installation, make sure that conduit connectors are tight. Install the rear access panel.

Installation should be performed by qualified personnel. In many areas there are independent installers who are experienced in Electro-Mech Scoreboard Co. product installations. You can contact Electro-Mech Scoreboard Co. to determine if we can help you locate an installer.

OPERATION

After installing the scoreboard and the SCORELINK 300 RF MODEM SYSTEM, turn the power to the scoreboard and the control console. The scoreboard should turn on and the operator should be able to control it from the console. Refer to the scoreboard owner’s manual for console operation.

You should reset the scoreboard each time that it is turned on. Test out all the functions to ensure that the scoreboard is operating properly. Electro-Mech Scoreboard Company strongly advises that you unplug the control console and the transmitter and turn the power to the scoreboard off when the scoreboard is not in use. The control console can’t turn the scoreboard off. This action will help protect the scoreboard, control console, and the SCORELINK 300 from power surges and lightning strikes. Important: The transmitter and control console are not weatherproof. Do not expose them to rain or leave them outside between games.

SERVICING THE SCORELINK 300 RF MODEM SYSTEM

While your SCORELINK 300 RF MODEM SYSTEM was designed for years of trouble- free operation, some problems may occasionally occur. Our trained personnel at Electro- Mech Scoreboard Company are ready to answer your questions from Monday to Friday during the hours of 8 AM to 5 PM Eastern Standard Time. Be sure to know your model number when calling. Our convenient toll free number is listed at the bottom of every page in this manual. While there are no user repairable parts inside the transmitter or the receiver, there are some easy tests, which will aid in determining the cause of the problem. If possible, perform these tests before calling for assistance.

Transmitter Test Make sure that the transmitter power cube supply is plugged in, the control console power cord is plugged in, and the extension cable connects the console to the transmitter. When the system is installed and turned on, the On LED indicator is lit and the Signal LED indicator turns on and off at a rate that varies with the amount of data that is transmitted. If the On LED indicator is not lit, the problem may be in the power cube supply. Check the 115 VAC receptacle into which the power cube supply is plugged. If the Signal LED indicator does not turn on and off, the problem may be in the control console or the transmitter. In this case, perform the Bypass Test.

Receiver Test When the scoreboard is turned on and the receiver (inside the weatherproof enclosure) is detecting a strong signal, the On LED indicator is lit and the Signal LED indicator is green. The Signal LED indicator is yellow / orange when a weak signal is detected, and red when no signal is detected. The weatherproof enclosure has a hinged door with a latch on one side. Unfasten the latch and open the door to view the receiver. Figure 8 shows the receiver.

If the On LED indicator is not lit, the problem may be in the power cube supply. The lack of a strong signal may indicate a problem in the transmitter or receiver. Perform the Bypass Test.

Bypass Test 1.Carry the control console and the ¼” stereo extension cable to the scoreboard. 2.Remove the rear access panel. For scoreboards with more than one rear access panel, remove the rear access panel to the section of the scoreboard to which the receiver cables are connected. 3.Plug one end of the ¼” stereo extension cable into the ¼” stereo jack on the rear plate of the control console and the other end into the ¼” stereo jack behind the access panel. 4.Plug the control console power cord into a 115 VAC power source. 5.Check the scoreboard to see if bulbs or LEDs turn on. Press control console keys to check the scoreboard operation. 6.If the scoreboard can’t be operated in this configuration, the problem is in the scoreboard or control console and not the SCORELINK 300 RF MODEM SYSTEM.

Receiver Removal and Replacement 1.Make sure the power to the scoreboard is removed. 2.Open the weatherproof enclosure door. 3.Unplug the male plug from the Power jack. 4.Unplug the green connector from the Signal jack. There is no need to disconnect the wires that are attached to the jack. 5.Remove the two gold hex nuts that hold the receiver on the mounting plate inside the weatherproof enclosure. 6.Remove the receiver from the weatherproof enclosure. 7.Insert the replacement receiver on the mounting plate inside the weatherproof enclosure. 8.Fasten the receiver with the two gold hex nuts. 9.Insert the male plug into the Power jack. 10.Insert the green connector in the Signal jack. 11.Close and latch the weatherproof enclosure door.

Figure 9 shows the wiring diagram for the green connector on the receiver in case the wires are disconnected from the green connector. The insulation should be stripped approximately ¼” off the ends of these wires. Insert the wires into the connector openings according to figure 10. Use a small flat blade screwdriver to tighten the wires into the green connector.

Receiver DC Power Cube Supply Removal and Replacement 1.Make sure the power to the scoreboard is removed. 2.Open the weatherproof enclosure door. 3.Unplug the male plug from the receiver Power jack. 4.Cut the plastic tie wraps that hold the DC power cube supply in place. 5.Unplug the DC power cube supply. 6.Plug the replacement DC power cube supply into the receptacle. 7.Insert the male plug into the receiver Power jack. 8.Close and latch the weatherproof enclosure door.
