Advantech's new PCM-9550F/9550FM operates without a fan at
low power, typically 3 amperes at 5 volts, supports numerous
peripherals, and is an excellent core technology for medical
equipment and POS systems, with a long product life cycle. It is a
EBX Biscuit PC single board computer (SBC) with an onboard
Intel low power Pentium® MMX™ 266 MHz processor, video input/
output (PCM-9550FM), a VGA/LCD controller, a PCI audio
interface, a PCI Ethernet interface, and 8 digital inputs and
outputs. Its design is based on the EBX form factor that supports
the PC/104-Plus interface for ISA/PCI module upgrade. Other onboard features include a 512KB 2nd level cache, 2 LPT, 2 USB,
Fast IrDA and 4 serial ports: 3 RS-232 and 1 RS-232/422/485.
The SSD solution supports both DiskOnChip®2000 and CFC.
PCM-9550 also provides some features for POS applications; two
to note, COM port with +5 V/ +12 V select by jumpers and digital
I/O for a cash drawer with isolated digital output.
SBC with EBX Form Factor, PC/104-Plus and Pentium®
Processor Available Now
With this board and its EBX form factor and PC/104-Plus
interface, system engineers can develop their own products or
buy them off for the shelf for this board. Up to four EIDE devices
can be supported as well as two FDDs.
1st EIDE
2nd EIDE
FDD interface
4 COM ports
Digital I/O
True multimedia SBC
The PCM-9550 F/M supports 3D audio and complies with the
AC97 standard. The PCM-9550 FM combines audio, video-in and
TV-out, and network functions on a single board computer the
same size as the EBX form factor standard. It provides video
capture that supports RCA connectors and S-Video connectors
via optional cable kit, and video-out function which supports
NSTC and PAL formats.
