Predator Express™ RS232 Hardware

Predator Express Hardware Overview

What is Predator Express Hardware?

Predator Express Hardware is an affordable 4 and 8 port RS232 PC solution. It includes a plug and play PCIe card and a 4 or 8 port hub to network CNCs, robots and PLCs to your Windows based PC. Up to 4 PCIe cards can be installed in a single PC. Predator Express Hardware supports transfers of CNC programs, offsets and parameters. It supports a wide range of CNC protocols for dripfeeding, downloading, and uploading via RS-232. Choose from these components:

  • 4 port PCIe Card and Hub
  • 8 port PCIe Card and Hub
  • DB9 and RJ45* style RS232 Ports

NOTE*: RJ45 style hubs are only available with the 8 port hub.

Why use Predator Express?

  • Network up to 32 RS232 based CNCs, robots and PLCs
  • Surge Suppressed RS232 Ports
  • DNC Send, Receive and Dripfeed on all ports
  • Supports High Speed Machining
  • Supports Predator CNC Editor
  • Supports Predator DNC
  • Supports Predator MDC
  • Supports Predator Virtual CNC
  • Supports Predator RCM
  • Supports Predator Touch HMI
  • Supports Predator BCRs
  • Supports Predator MDC Adapters
  • Supports Predator CycleLocks and EditLocks
  • Supports Predator Grizzly Cables
  • Optionally use existing RS232 cables
  • Replace rotary ABCD switch boxes
  • Open Architecture - Not Proprietary
  • Eliminate walking back and forth via Remote Request*
  • Upgrade both cards and hubs as needed

NOTE*: Requires Predator Express Hardware and Predator DNC.


Older systems can upgrade from PCI cards to PCIe cards and utilize the same 4 and 8 port hubs. This maintains the investment in hubs and cabling as PCs get upgraded or swapped out.
