PDA-100 Photodiode Array Detector
4-10

4.9
Faulty DX-LAN Communication
•
PDA-100 not detected on DX-LAN
When the host computer is powered up, PeakNet 6 or Chromeleon scans the
DX-LAN for all installed instruments. If the PDA-100 power is off, the
detector cannot be identified. Before turning on the computer power, make
sure the detector power is turned on.
•
DX-LAN interface incorrectly installed
Check the following (for installation instructions, see Section B.3.6):
•
A 10BASE-T DX-LAN cable (P/N 960281) must be connected
between the
DX-LAN
connector on the PDA-100 rear panel and the
Ethernet hub (P/N 056909).
•
A 10BASE-T DX-LAN cable (P/N 960281) must be connected
between the Ethernet hub (P/N 056909).and the
DX-LAN
connector
on the host computer’s internal DX-LAN interface card.
4.10 No Spectra Collected
•
Spectral range was not programmed
Select a spectral range in the PGM file or control panel.
•
Detector and PGM file (or control panel) connected to different
timebases
Add the PDA-100 to the same timebase as the PGM file or control panel.
4.11 Low Spectral Resolution
•
Bunch width too wide
Select a bunch width setting of 1 nm and then recheck the resolution.
•
Sample bandwidth too wide
Select a sample bandwidth that includes only the absorbing wavelength.
When using 10BASE-T cabling, always install an Ethernet hub. If you
simply plug the 10BASE-T cable from the PDA-100 into the connector
on the host computer’s DX-LAN card, the connection will not work.
