COMPARING THE i230 PCMCIA CARD W/ THE i200 PCI CARD PRODUCT LIST > i230 >
The iNet-230 PCMCIA instruNet card controls an instruNet network (i100 and/or i4xx Card Cages) via a PCMCIA card slot. The iNet-230
is similar to the iNet-200 PCI controller, except it enables one to do data acquisition with instruNet from a
laptop computer. Also:
External Power Supply
The iNet-230 requires an external power supply:
#iNet-312.8, 110/220VAC, 5V/3.5A, +12V/1.5A, -12V/0.8A, 3 prong USA plug #iNet-312.8eu, 110/220VAC, 5V/3.5A, +12V/1.5A, -12V/0.8A, 2 prong Euro CE plug
No Counter/Timer Signals
The controller counter/timer signals (there are 10 of these on the iNet-200 pci card) are not accessible on
the iNet-230, due to space considerations. If one wanted access to of these signals, they could solder a
small wire to a pin, and route it outside the card, to a connector, which is mounted on the iNet-230
housing. If using an input, it would be recommended that they place a 1K resistor in series w/ the pin, to
protect it from overvoltage. This is a little messy, and is only advocated for those who are comfortable
with kind of activity.
The iNet-230 is compatible with Windows computers
with ≥ 1 available Type II 16bit Pcmcia slot.
Heat & Power Considerations
The iNet-230 card draws about 300mA at 5Volts from the PCMCIA socket. Consequently, it heats by
1.5Watts. The pcmcia specification says cards can draw a maximum of 1Amp and heat by a maximum of
5Watts. Therefore, the iNet-230 should not get too hot, since Laptop computers should provide adequate
ventilation to for up to 5Watts. Yet some laptops do not do well here, since they are focusing on being
light weight and being about to survive for long periods of time on batteries. One way to reduce the
temperature inside a laptop is to place the laptop on several rubber supports so that it sits about 2cm off
the table. This allows cool air to move over the bottom surface of the laptop, and subsequently draw heat
away from the system.
All PCMCIA cards are inherently vulnerable to structural failures, since they have very little material, and
sometimes inadverterantly absorb powerful forces on small surface areas. The iNet-230 has 2
connectors, a DB25 and DIN5 that are large, strong, & not prone to breaking. The plastic supports around
the DB25 are also strong. The weak link is the card itself. Therefore it is recommended that the card be
handled with care, and inserted into the computer without bending. Also, one should attach the DB25 and
DIN5 cables to the card before insertion, and not later yank on the cables.
iNet-230 Pcmcia Revision #2 Introduced June 2004
The i230 pcmcia product enclosure was redesigned mechanically June 2004. The new version ("Rev 2") has a more standard enclosure that cables to an included "Pcmcia 25 pin to DB25" Cable, instead of a DB25 connector that is mechanically attached to the pcmcia card's frame. This does not effect software, price, performance or part numbers. In summary, Rev 1 and Rev 2 are interchangeable.
