Example applications and the products we typically recommend for them.
Factory automation
Many serial devices on one PC
- Challenge
- Lines still run RS-232C controllers, scanners and meters, and a PC has few or no COM ports.
- Contec solution
- COM-4C-PE board with four RS-232C ports, up to 16 boards per system.
- Why it fits
- Works as standard COM ports through Win32, Linux, .NET SerialPort or PySerial.
Industrial PCs
Serial ports in compact PCs
- Challenge
- Small industrial PCs only take low profile cards but still need several serial ports.
- Contec solution
- COM-4C-LPE low profile PCI Express board with four RS-232C ports.
- Why it fits
- Fits low profile or standard slots with the included bracket, up to 921,600 bps.
Test & measurement
GPIB instruments on a modern PC
- Challenge
- Test systems control GPIB instruments, but new PCs have no GPIB slot.
- Contec solution
- GP-IB(USB)FL micro converter that adds GPIB through a USB port.
- Why it fits
- IEEE-488.1/488.2 compliant with Windows and LabVIEW driver libraries.
Existing systems
Keep PCI systems running
- Challenge
- Installed systems with PCI slots need more RS-232C ports without a redesign.
- Contec solution
- COM-4(PCI)H PCI board with four RS-232C ports and 128-byte FIFOs.
- Why it fits
- Standard COM ports and up to 16 boards in a single system.
