CNCnet DNC integrates your CNC machine controls with serial (RS232) interface directly into your network and controls an unlimited number CNCs simultaneously on a single computer. Cabling can either be made by using a direct cable, a serial - network interface or a wireless module. No need for Computers or special terminals at the shopfloor area.

All transmission activities can be controlled by the operator panel of the machine.

Protocols included: ACIERA, DDCMP, Mazatrol CMT, MEFI/Trans, BPA/9, LSV2, PRN, 3964/3964R, Heidenhain, PTR-Simulator

Supports various interfaces: real or virtual COM ports (USB, WLAN, device and COM Servers)
Setup of machine specific transmission parameters (leading - trailing sequences / characters, change or replace characters, send specific HEX ASCII codes). Recharge (drip feed) operation mode for large programs (SW / HW handshake)
Suitable for Microsoft Windows XP (x32-x64), Vista (x32-x64), Server 2003 (x32-x64), Server 2008 (x32-x64), Virtual PC 2004 – 2007, Virtual Server 2005 and Hyper V Server 2008
Pre-built machine specific setup files for more than 800 types of machines are available from Inventcom
Integration of Pre- and Postprocessors for automatic NC file manipulation (Replace Characters, separate and modify NC files, format tool preset data).

You say "unlimited number of simultaneous communications with CNC's", how do you get around the operating system limitation of 256 COM ports?

[inventcom]

1) A virtual serial port is an emulation of the standard serial port. This port is created by software which enable extra serial ports in an operating system without additional hardware installation (such as expansion cards, etc.). Unlike a physical serial port the virtual one can be assigned any name (COM255, VSP33, etc.). It is possible to create unlimited number of virtual serial ports in your PC. The only limitation is the computer performance, as it may require a substantial amount of resources to emulate large numbers of serial ports.

2) We do also have a driver for IP based communication with external serial servers, no RS232 needed at all (see picture)

All,
as there are lots of questions about cabling here I've added typical cable contruction examples that should fit to 99% of all CNC's. Be aware that there are some older control types (e.g. Heidenhain) that require straight, not crossover wiring as the SEND / RECEIVE and Handshake wires are already crossed over inside the control.
This Wiring instructions are also applicable to other DNC software.
