EXP-ISO-COM8 EPIC Octuple Serial Interface EXP-ISO-COM8

  • Octal Serial Interface

EXP-ISO-COM8 is an EPIC add-on module, comprising eight independent and flexibly configurable serial ports for RS232 / RS422 / RS485 line levels.

All interfaces are galvanically isolated, thus insuring the integrity of add-on board and processor module. The individual operating modes and the optional terminations are selectable using jumpers. DB9 connectors and four IDC10 headers for cable stubs to DB9 available.

EXP-ISO-COM8 is powered with a single 5 V supply from the PCIe /104 Express connector. It runs under Windows XP, Windows XP Embedded, and Linux operation systems.

Drivers
Windows XP (x86 / x64) OXPCIe958
Windows 7 (x86 / x64) OXPCIe958
Linux* Use 8250_pci.ko module.
 

 Linux*: The driver was tested using Ubuntu Linux 11.04 at a kernel version of 2.6.38. Any other kernel containing the 8250_pci.ko module should work as well. However, it might be necessary to modify the kernel to allow all 8 serial ports to be present.
