CI-132 Series User’s Manual
To prevent the boards from damage caused by lighting or high potential voltage,
TVSS
(Transient Voltage Surge Suppressor) technology is introduced in some
models to protect the board. This is critical to harsh environment such as factory.
ASIC Design, Compact Size
The CI-132 Series is equipped with MOXA customer-designed ASIC chip, which
replaces lots of conventional IC and hence reduces the board to half-size, increase the
operation performance, and lower the failure rate of the board. Full range of I/O
addresses and IRQs are available. In addition, with
on-board EEPROM
for storing
the configuration data, the family is designed without jumper or switch. These
features make each port on the board truly independent to any other port and thus
compatible with most existing non-intelligent boards. Because the family is so
flexible in hardware configuration, it is compatible virtually with all kinds of other
manufacturer's non-intelligent multiport boards using 16550 UART.
CAP Address
Instead of using traditional jumper or switch for IRQ and I/O address settings,
hardware configuration of each port is easily set by DOS utility,
Io-irq.exe
, which
read and write the on-board EEPROM for configuration information through the
CAP
(
Configuration Access Port
)
address
. The CAP address is the only channel
via which the configuration utility Io-irq.exe can access the board, which is identical
to
the first port's base I/O address
.
The jumper,
JP1
, is designed in case of that users forget the CAP address. Normally
JP1 is left open. When JP1 is short, the CAP address is forced to a fixed I/O address,
0xA700
. While doing quick hardware installation, JP1 is required to be shorted,
