Watch Dog Installation Instructions The Watchdog consists of an interface device that connects to a COM port on your computer. The computer communicates with the interface device constantly. This is how the interface device knows that everything is okay. If the computer does not continue "talking" to the watchdog, the watchdog tells the UL approved Intelligent Power Module to shut power off to your computer. After a preset time, the computer is turned back on. If the computer still does not respond the watchdog attempts to power it off and on again and at the same time will close its contact closure. The contact closure can be tied to a dialer or an alarm system that can notify an operator that the computer is down and cannot be rebooted. 旼컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � COMPUTER -> INTERFACE -> POWER SWITCH �> AC WALL OUTLET ControlReady Operation: For ControlReady, a playlist is run from an empty automation deck. The playlist basically needs to send the letter O every 5 seconds (with COMTALK command). The Watchdog is setup default to expect an O every 20 seconds. Thus the computer has plenty of chance to send the O. The playlist repeats with a GOTO 1 command. In English the playlist looks like this: 1 COMTALK (string is O com port is whatever you want. Baud rate is 9600 N81) 2 DELAY FOR 5000ms (5 second) 3 GOTO 1 Jumpers: The Watchdog has several jumper settings. These control the timing. For example how often it expects the O, how long it waits for the computer to reboot after power is applied etc. WireReady has pre-configured the Watchdog to these settings, so you will not need to change these settings. A 1 indicates an closed jumper. A 0 indicates a removed jumper. An '*' indicates preferred settings for WireReady. Power cut off: J4 controls the length of time the Watchdog will turn off power when it reboots the computer * 1 Cut power for 10 seconds 0 Cut power for 20 seconds Boot delay: J5 J6 and J7 control how long the Watchdog will wait for the computer to start communicating with it after rebooting, before the Watchdog will try rebooting the computer again if no communication received. This is to give the computer enough time to reboot and start communicating with the Watchdog. This setting also controls how long the Watchdog waits after it receives power, before it will try to reboot the computer if no communication is received. J5 J6 J7 0 0 1 1 Min boot delay * 0 1 0 2 Min (DOS Computers) 0 1 1 3 Min 1 0 0 4 Min * 1 0 1 5 Min (Windows95/98 Computers) 1 1 0 6 Min 1 1 1 7 Min 0 0 0 8 Min Communication wait: J8 and J9 control the length of time between when the Watchdog receives communication from the computer, and when it will reboot if no more communication is received. J8 J9 0 1 Send 'O' every 5 sec 1 0 every 10 sec * 1 1 every 15 sec 0 0 every 20 sec Disabling the Watchdog: You'll want to disable the watchdog anytime you need to shut down or exit ControlReady to DOS. This is since if we stop running the Watchdog thinks there is a problem and it will shut your computer off and turn it back on! Note: To enable the remote disable switch, jump the right pins of j11 and j12 together and jump the left pins of j11 and j12 together. Two pins on the barrier strip can be shorted with a momentary push button. (N- and N+ on the barrier strip) OR... The Intelligent Power Module can be set to 'I' to prevent power from being shut off. When back in ControlReady, it should be set to O to enable the Watchdog. LED Lights: The CPU-OK LED should flash green. The RS232 led will flash green when in watch dog mode. The RS232 led will stay solid green when in sleep mode. (when disabled with the remote switch) Alarm will go red if the device has tried to shut off the computer twice. Contact Closure for tripping an alarm or auto-dialer: A contact closure relay will close if the watchdog attempts to power down your computer twice. The points on the barrier strip ALM and COM. Connecting the Watchdog NOTE: When first setting up the Watchdog, do NOT plug a necessary computer into the Intelligent Power Module (IPM). Wait until you are sure that the Watchdog and IPM work properly before plugging the computer into the IPM. Otherwise, you might continuously reboot your computer. Connect the included RJ adapter to the com port on your computer. This com port must be the same one used in the Comtalk command sending the O to the Watchdog. Connect one of the included RJ cables between the RJ adapter and the Watchdog. This MUST be connected to the RJ jack closest to the power jack on the Watchdog. Connect the other RJ cable between the other RJ jack on the Watchdog and the RJ jack on the Intelligent Power Module (IPM). Start the playlist which is sending the O to the Watchdog. Make sure that the RS232 LED on the Watchdog is flashing. This LED flashes each time it receives an O from the computer. If the RS232 LED is not flashing, check the connections between the computer and the Watchdog. Make sure that you are connected to the correct com port. Make sure that the RJ cable between the computer and the Watchdog is connected to the RJ jack closest to the power jack on the Watchdog. Testing the Watchdog Once you have the proper connections, you will want to test that the Watchdog operates properly. Do this testing without plugging your necessary computer into the Intelligent Power Module (IPM). Use a monitor, a table lamp, or some other electrical device which you do not need kept on. Make sure that the IPM switch is on 'O'. If the IPM switch is on 'I', it will ignore commands from the Watchdog, and remain on at all times. With the playlist running, sending O characters to the Watchdog, make sure that the Watchdog will not disable the power on the IPM. Keep the playlist running for at least 10 minutes to test this. If the Watchdog does disable the power, even the playlist is sending the O character, you will need to check your connections, and test again. Once you confirm that the Watchdog keeps power on correctly, stop the playlist. The RS232 LED will remain off, because the Watchdog is no longer receiving the O character. After about 20 seconds, the Watchdog should disable the power on the IPM. You will also see the red Alarm LED on the Watchdog light. About 10 seconds later, it should return power to the IPM. [NOTE: If you stop the playlist after running it for less than the boot delay (set up with jumpers J5 J6 and J7) the Watchdog will not cut the power. This is one reason why we recommend you first let the playlist run for at least 10 minutes.] If power is not disabled to the IPM, and the red alarm LED does not light, then the Watchdog is not operating properly. If the red alarm LED does light, but power is not disabled to the IPM, then the switch on the IPM SWITCH might be on 'I'. If the switch is on 'O', but power is not disabled, then the IPM is not operating properly. If everything else works properly, but power does not return after 10 seconds, then the Watchdog is not operating properly.
