The HP JetDirect cards are network interface cards used in HP printers.
NOTE One board is required per Agilent 1100 stack. It is recommended to add the
LAN board to the detector with highest data rate.
NOTE The LAN board can only be used together with:
• a main board version G13XX-66520 (DAD/MWD/VWD/Pump/ALS) or
G13XX-66500 (FLD/RID) and above.
• a Agilent-ChemStation software revision A.06.01 or above.
