* The PCI-Express models, the ME-9000 PCI models (from Rev. 1.4 up)
and the ME-9000 CompactPCI models (from Rev. 1.2 up) are
provided with optional opto-isolation from PC ground („i“-models)
resp. with electrical insulation between the single ports („p“-models).
Note: Further versions on request (

The ME-9000 series is a high integrated serial interface board
designed for PCI-, PCI-Express- resp. CompactPCI-bus. It 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 with
up to 8 ports for RS-232 and/or RS-422/485 standard. The ME-
9000 PCI- and cPCI-versions adapt themselves automatically to
the level at the PCI bus of +3.3 V or +5 V (Universal PCI).
As a special the ME-9000 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.
The ME-9000i models provide opto-isolation of all serial ports from
PC ground. I.e. as seen from the application all ports refer to a
common, isolated ground (GND_C). The isolation voltage is 500 V.
ME-9000p models: each serial port is an electrically isolated
„island“ with separate ground (GND_x). It is ideal for noise-
sensitive environments in industrial control. The isolation voltage is
500 V.
