Other things that can cause errors are when the system powers up it does a system check before anything If it does not receive the responses back from the devices it s checking it goes into error If this occurs you should call the Larry McGee Company and request an RMA number as this problem needs to be addressed by the factory PWR ON LED This led should be lit whenever the power supply is plugged into the unit This led will always remain on regardless of any errors or power up sequence The ALRM ACK Button has the following three functions 1 Boot To Factory Defaults J2 on PCB the Log in jumper must be enabled i e on pins 1 amp 2 PM NID 1002 00 0H Page 9 October 2014 for this to work Power down the board and then press and hold the ALRM ACK button while powering up the unit All the front panel leds but the power will flash on and off signaling that you have the ALARM button pressed It will do this for 3 more seconds giving you a chance to release the button should you choose to cancel If you continue to press it for more than 3 seconds the leds will stop flashing and only the ERROR led will flash letting you know that it is now ok to release the button When you do the unit loads in the default factory settings CAUTION Do not remove power before this is complete If this it accidentally done it will not damage the unit but you will have unusable setting and will have to perform this operation again

When the board flashes all LEDs except the Power LED then stops it is ok to remove the power if necessary 2 Unit Reset when the unit is running if you press and hold this button for greater then four seconds it resets the unit Release the button when the front panel leds except the power turn off This is equivalent to removing power from the unit then restoring power 3 Alarm Acknowledge If there is an error the SYS ERROR led flashes along with the associated led that is in error If enabled the piezo sounds If you want to quiet the alarm press this button until the piezo turns off PM NID 1002 00 0H Page 10 October 2014 4 Setting Up amp Adjusting the Silver Box Physical Selections The following selections and adjustments are available Several parameters are set with jumpers or by adjusting pots e 2 wire or 4 wire operation e 600 Ohm or Hi Z termination Transmit Audio Level Receive Audio Level COR Positive Trigger Ground Trigger with or without 12VDC source or constant transmit Web site access Your LMnid Silver Box can be pre configured at the factory if you supply the necessary parameters A sheet will be provided with your Silver Box indicating how it was configured when it left the factory To configure your LMnid Silver Box remove one of the end panels and slide the cover off Figure 4 1 depicts the top view of the circuit board with the Ethernet module installed Do not remove the Ethernet
