We offer a special price for customers who buy two products, saving you money on one order. If you buy 1 piece you can visit our store to find the most suitable product DNC TITAN is a device used to transmit G-code programs to CNC machines, used for most CNC control systems on the market today such as FANUC, YASNAC, HAAS, OKUMA, MITSUBISHI, SEIMENS, MAZAK. ... designed to optimize and simplify the process of transmitting G code programs to CNC machines, replacing desktop computers and personal computers. Very high transmission stability. You can transfer the program to the CNC machine's memory, or drip a large program to the CNC machine through the CNC machine's DNC function, a solution for CNC machines with small memory but need to use large machining programs. large size functions of the DNC TITAN device 1: transfer program to cnc machine, can transfer into memory or drip large program in DNC mode of cnc machine. program can be transferred on USB 2.0 (USB up to 64GB) or in DNC device memory (DNC device memory is 4GB) 2: receive program from cnc machine to DNC device (save parameters of cnc machine, tool offset, machining program...) 3: Can copy program from USB to DNC TITAN memory or vice versa. 4: has 2 independent USB ports . There is 1 9-pin RS232 port to connect to the CNC machine. There is a 50-pin parallel port to transfer programs to older machines using FANUC 6M and 5M. There is 1 external DC12V power supply port There is 1 RS232 DP9-DP25 cable with software handshake There is 1 AC-DC power adapter included in the package 5: the device has RS232 handshake protocol which is "hardware handshake and software handshake". The cable included in the package is designed for software handshake, most CNC machines today follow the software handshake standard. If customers need to use hardware handshake protocol, please contact the store for instructions on how to make your own RS232 cable using hardware handshake style. Package includes DNC TITAN, 2 meter long RS232 DP9-DP25 cable, 12V AC-DC power adapter Customer service throughout the process of customer use. We can assist in setting up DNC TITAN and CNC working together Products are warranted for 1 year
