(4) Topic: WBK20 - PCMCIA/EPP Interface Card
Question: How do I configure the WBK20 in Windows 95 or Windows 98?
Answer: Insert the WBK20 into the PCMCIA slot. Windows 95/98 should recognize it and display a
window 'New Hardware Found' followed by a window 'Building driver data base'.
Select the option 'Select driver from disk provided by hardware manufacturer'. 'Install from
disk' is the next window. Provide a path to the floppy drive after you have inserted the disk that
came with the WBK20. It contains a file 'IOTWBK20.INF'. Select OK.
In the next window, select 'IOtech Inc' in the left box and 'IOtech WBK20: 1 Parallel Port' in the
right box. Select OK. At this time, it may ask for your Windows CD or certain diskettes. Then
you will be prompted to restart the computer.
The WBK20 will show up in ControlPanel/System/Device Manager/ Ports (COM and LPT) as
'IOtech WBK20: 1 Parallel Port LPT#'. Double clicking on this will show you the resources
(IRQ and I/O range).
(5) Topic: ECP and EPP
Question: My computer uses ECP. Is ECP the same as EPP?
Answer:
No; ECP (Enhanced Capabilities Port) is a different protocol than EPP (Enhanced Parallel Port).
If the WaveBook fails to communicate in ECP mode, make certain that the WaveBook hardware
is actually capable of ECP communications. This can be done as follows:
1.
Locate the LPT port communications chip on the main board, near the connector that the
parallel cable connects to. The chip is relatively large and is stamped “262-0301,”
or “262-0301, rev B.” A 262-0301 rev. B" chip supports ECP, the earlier rev does not.
Contact the factory in regard to upgrading.
Note that most units purchased before July
2000 do not have ECP support
.
2.
Verify the parallel port hardware is in ECP mode. For ports built into the computer’s
motherboard, the port is usually configured using the computer’s BIOS setup utility
(accessible during computer start up). See your computer's specific documentation
regarding accessing the BIOS setup utility and configuring peripherals.
3.
Verify the parallel port is configured [in the Windows Control Panel] as an "ECP parallel
port" and not "Parallel port."
(6) Topic: Sampling Rates
Question: Does the WaveBook really collect data at 1 MHz and what should I expect on my PC?
Answer: Yes, the WaveBook samples at 1 MHz. But your computer may not. The PC’s performance is a
function of the hardware configuration, operating system, background task, and other factors.
The PC could very well be a bottleneck in regard to sampling.
Question: What transfer speeds can I expect from a standard 8-bit parallel port?
Answer: A typical computer will achieve 80K to 90K samples/sec [through-put to the PC].
