Page: 12 / 120

The ME-90 PC/104-Plus series is a serial interface board com-
pliant to PC/104-Plus specification 2.3 with PCI interface (3.3 V or
5 V) and a „looped through“ ISA bus. I.e. if you have a PC/104-Plus
single board computer, which supports PCI- as well as ISA-bus you
can combine the ME-90 PC/104-Plus with ISA-based PC/104
boards without problems.
The ME-90 PC/104-Plus provides a PCI controller with integrated
Octo-UART of type EXAR XR17D158IV for extended temperature
range. The UARTs are register compatible with the 16550 and
provide an integrated 64-byte transmit and receive FIFO for each
port. The board allows transfer rates up to 921,6 kBd. There are
versions available either with 8 RS-232, 8 RS-422/485 or mixed
with 4 RS-232 and 4 RS-422/485 ports. The routing of the PCI-
bus signals CLK, IDSEL and INT0# is done by jumpers. The ME-90
PC/104-Plus adapts itself automatically to the level at the PCI-bus
of +3.3 V or +5 V (Universal PCI).
With its extended temperature range from -40 °C to +85 °C it is
the ideal solution for industrial applications.
As a special the ME-90 PC/104-Plus offers an 8-bit multi-I/O port
for customer-specific extensions. See also chapter 4.1 "ME-9000
Multi-I/O Driver" from page 61 on.
1.4 System Requirements
The ME-9000/9100/9300 can be installed into any PC with an
Intel® Pentium® or compatible computer with a free standard
PCI-, PCI-Express- or CompactPCI-slot (depends on model).
The ME-90 PC/104-Plus can be used as a PCI-based peripheral
board in a PC/104 stack.
The board is supported by the Meilhaus Electronic Intelligent Driver
System (ME-iDS).
1.5 Available Software
The provided software enables quick integration of the boards
under all common operating systems. Using Windows the ports
can be accessed as standard COMports.
