Troubleshooting
Sealevel Software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting
procedures. By using this software and following these simple steps, most common problems can be
eliminated without the need to call Technical Support.
1.
Identify all I/O adapters currently installed in your system, including onboard serial ports,
controller cards, sound cards, etc. The I/O addresses used by these adapters as well as any
IRQs (if any) should be identified.
2.
Configure your serial adapter so that there is no conflict with currently installed adapters. No
two adapters can occupy the same I/O address.
3.
Make sure the serial adapter is securely installed in a motherboard slot.
4.
Ensure that the Sealevel Systems SeaCOM software has been installed on the machine so that
the necessary files are in place to complete the installation.
5.
When the COMM+16.PCIe
is configured properly, Sealevel’s WinSSD utility and a loopback plug
can be used to check communications. You can make a simple Loopback in the field by
connecting the TX and RX pins. If you decide to test the Modem Control Signals, a full pin
loopback plug will be required. Details on loopback plugs are included within WinSSD. Contact
Sealevel Systems if you need further assistance.
6.
When testing the COMM+16.PCIe
in loopback mode, you should see both the TD and RD
echoed as data on the screen. The loopback test first transmits a HEX pattern, 55AA, and then
an ASCII string of data. If this test passes, then the COMM+16.PCIe
is ready for use in your
application.
7.
Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This
will eliminate any software issues and identify hardware conflicts.
