C50 (Rev. 1) User Manualthe power from the parallel port. Itcan take the +3.3 or +5vdc signalfrom the parallel port and deliversolid +5vdc at 24 milliamps. Output pins 1, 2, 3, 4, 5, 6, 7, 8,9, 14, 16, 17. Input pins 10, 11, 12, 13, 15. The common terminal to pins 2-9 can be ground or +5vdc.Forget about grounding problems.Easily connect your pin by usingyour close by ground connection.No need to be an electronicsexpert to ground all your stuff. Theboard has a jumper that allowsyou to select if the commonterminal to pins 2-9 will carry aground or +5vdc. So if you areconnecting encoders or proximityswitches, you can select it toground. If you are connectingGeckodrives or limit switches, youcan set It to be +5VDC.other external safety monitoringdevice.Works directly with popularCNC hardware and software.Such as Geckodrive, DeskCNC orRutex, and parallel port controlsoftware, such as mach2, LinuxEMC, TurboCNC, CNCPlayer,CNCZeus and others. (Not alltested).All TTL 5VDC signals. Interfacedirectly with parallel port interfaceproducts and other CNC4PCcards. 5VDC (TTL) cards are verycommon among automationdevices.Screw-On connections for allterminals. You only have toscrew-on the wires to make allyour connections.External Enable Pin (EN). Theboard has a pin that allows you toenable/disable all the outputs andinputs 11, 12, 13 and 15 at once.Only input 10 will be alwaysenabled. The board requires+5vdc in the EN pin. If it is notpresent, it will send all the outputsto high impedance and the inputsto an high. You can use this toenable or disable the systemmanually, or you can install anexternal Safety Charge Pump orRevision: 4/16/2012 http://cnc4pc.com/TechDocs/C50R1_User_Manual.pdf 2/14
