We test our cables before shipment wire-for-wire for accuracy, signal consistency and continuity. Their lead-wires use a thicker gauge wire than most off-the-shelf serial cables. Their foil shield and drain wire reduces signal noise interference. We solder custom RS232 cables onsite using high quality well-insulated cables. Are you connecting to a manual switch box? Select YES if you are connecting to an A/B selector switch box or something similar.If you have a cable wiring pinout diagram, please email or fax it to us.What D-Sub connector do you need for the PC/Switch Side of the cable – DB9-pin or DB25-pin? Male or Female?īelow are the standard typical connectors for most machines Left image (DB9 Female) What D-Sub connector do you need for the Machine Side of the cable - DB9-pin or DB25-pin? Male or Female? Specify the connectors needed on both ends of the cable.The signals are RTS/CTS and are typically only required on vintage machines or applications not related to CNC. RTS/CTS: Hardware handshaking - this RS232 wiring configuration would use two additional wires, CNC requests data, then pc sends etc. Uses software XON/XOFF control when it sends the data, RTS (request to send) and CTS (Clear to send) signals jumped out so it is always ready to send or receive. XON/XOFF: Software handshaking (standard protocol) - XON/XOFF is the typical RS232C cable pinout wiring standard. Are you going to use XON/XOFF (software) or RTS/CTS (hardware) Handshaking? If you’re not sure, that’s okay.Mitsubishi, Fannuc, Yaskawa, Yasnac, Fadal, Haas, Brother, etc.) Specify CNC controller used on your machine.Mazak, Mori Seiki, Okuma, OKK, Doosan, Hardinge, Makino, etc.) Specify machine make and model to help confirm the cable will be configured properly for your machine.If you need exact length, select the longer length when adding to cart and specify in additional order notes your specified length.
