2-12 Installing the PCLTA-20 Card
LonMaker Integration Tool or any other LNS tool does not work. You will notice that
when the network is open the tool indicates that it is unable to communicate with the
PCLTA-20. This is because the PCLTA-20 card features a downloadable firmware
image and the LONWORKS Plug ‘n Play control panel must be reconfigured to support
LNS. The NI Application must read PCL10VNI, and not PCC10L7 or PCL10L7.
If, after pressing the test button after installation of a PCLTA-20 card, an **Error-
Image Load Failure** message is reported, then there is either an I/O conflict with the
PCLTA-20 card, or the card is broken. If there is an I/O conflict, then Windows NT is
not granting an unused I/O port to the PCLTA-20 driver. To rule out a broken card,
check the card using a Windows 95/98/Me or Windows 2000 configuration known to be
reliable.
Automatic Flush Cancel Issues
If the PCLTA-20 card appears to install and test normally, but still will not
communicate on the network, check to be sure that the Automatic Flush Cancel
checkbox in the LONWORKS Plug ‘n Play control panel applications is still in its
default (set) state. For more information, see the Automatic Flush Cancel section in
Chapter 3.
