Moxa's line of embedded PC/104 and PC/104-Plus serial modules for industrial applications is designed to operate reliably in a -40 to +85°C temperature range, and the on-board 15KV ESD protection and 2KV optical isolation features make the boards an attractive alternative to other similar products on the market. The CA series follows the original PC/104 standard, which uses a 104-pin ISA bus. The CB series of PC/104-Plus modules incorporates both the 104-pin ISA bus and the 120-pin PCI bus. Both series' drivers support all major operating systems, including DOS, Windows 9x/NT/2000/XP/2003/Vista, Windows XP Embedded, and Linux 2.4/2.6; optional DB9 and DB25 connection cables are available for connecting to many types of serial device. The device drivers for the two series make full use of the 128-byte Tx/Rx FIFO and on-chip H/W and S/W flow control.
