    CardBus interface. The CARDBUS-CTL signal is used to control the CB-FRAME# blocking. Please refer to the SB-X270 schematics for implementation details. Only 3.3V PC-Cards are supported. NOTE: this solution does not allow card insertion/removal (hot-plug) while the system is powered. CompuLab LTD.

  • Page 34: 10/100 Mbit Ethernet Port

    The Ethernet port’s interface is either through the standard RJ45 connector on the front panel or through 20-pin FPC connector P31. If the P31 interface used, the appropriate FPC cable and RJ-45 module can be obtained from CompuLab. 4.4. RS-232 and RS-422/485 Serial Port Drivers The CM-X270 module has on-board RS-232 drivers for the COM-A port.

  • Page 41: Operating Temperature Ranges

    The temperature testing and certification method is explained in the "Industrial Temperature Support" page, available following the [Products] >> [Industrial Temperature] links in CompuLab's web-site. The mating CM-X270 should be ordered for the same temperature range as the SB-X270. For example, it is not valid to use a SB-X270 manufactured for industrial temp range with a CM-X270 manufactured for commercial temp range.
