C11T (Rev.2.1) User Manual Optoisolated Drivers Monitorcircuit. Buffered outputs. Outputs arebuffered through the use of highspeed and high current buffersallowing the card to output the signalswithout using the power from theparallel port. It can take the +3.3 or+5vdc signal from the parallel port anddeliver solid +5vdc at 24 milliamps. Microcontroller based SCHP.This board comes with amicrocontroller that allows theimplementation of a complex algorithmfor sampling and analyzing the SCHPsignal. Built-in Variable Speed Control.It has an optoisolated analog 0-10VDC output that will convert a stepsignal into an analog signal that canbe used to command a commercialVFD. This analog can be adjustedusing on-board potentiometer, so thisboard can be adjusted to othervoltages. Monitors E-Stop, Safety ChargePump, and Drivers (it onlymonitors (it only monitorsG320/340, G203, G210/201 ViperServomotor and Dugong drives atthis time). Enables and disables the drivers. Microcontroller Based MonitorSystem. Two Built-in ElectromechanicalRelays with NO and NC positions. Status LEDs on all inputs andoutput connections.No more guessing. You can SEE allyour signals. Save valuable time andbrainpower for CNCing. To avoidremaining current to the main load(driver or other device), all theindicator LEDs are driven byindependent buffers of the ones thatdrive de output. 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 2-9can be ground or +5vdc. Forgetabout grounding problems. Easilyconnect your pin by using close byground connection. The board has aJumper that allows you to select ifthe common terminal to pins 2-9 willcarry a ground or +5vdc. External Enable Pin (E-Stop). Theboard has a pin that allows you toenable/disable all the outputs atonce. The board requires +5vdc inthe EN pin. If it is not present, it willsend all the outputs to ground. Youcan use this to enable or disable thesystem manually, or you can installan external Safety Charge Pump orother external safety monitoringdevice. This pin acts as hardwaredisable. Works directly with popular CNChardware and software. Such asRevision: 9/23/2010 http://cnc4pc.com/TechDocs/C11TR2_1_User_Manual.pdf 2/24
C11T (Rev.2.1) User ManualGeckodrive,Rutex, Keling, Viper,Dugong, and parallel port controlsoftware, such as mach2, LinuxEMC2, and TurboCNC. All TTL 5VDC signals. Interfacedirectly with parallel port interfaceproducts and other CNC4PC cards.5VDC (TTL) cards are very commonamong automation devices. Screw-On connections for allterminals. You only have to screwonthe wires to make all yourconnections. All pins can be used in aconcurrent manner.You can use all the input or outputpins in a concurrent manner. Forexample, if you are using output pin#1 to control the Built-inElectromechanical Relay, you canalso access that signal from theoutput pin on the board or from theDB25 connector for output. Eachconnection will not affect the othercurrent from the other connection.3.
