D-Link DE-620CT Printer Port is Incompatible or not Functioning Correctly, Adapter is Faulty

LEDs: check that Transmit and Receive LEDs are blinking when attempting find the server. For UTP the Ln (LINK) LED should be on when cable attached, off when removed. (You can also check the hub LINK LED which operates in the same manner but on its own cable pair)

COLlision	May be active from time to time but not constantly.
	The more network traffic the more times this will light
JABber	Should never be active. If this led is active suspect a problem with the adapter
Ln/Rx	Link will be on when you attach the UTP cable (not BNC)
	Receive will flicker when traffic is being received from the network
Tx/On	Transmit will flicker when traffic is being sent to the network
	On will be active whenever the adapter is powered

Compatibility problems

In cases of severe compatibility you may have to use an alternative device. If you are fortunate enough to have a PCMCIA Type II slot you’ll be able to use the D-LinkDE-650CT or DE-660CTPCMCIA Ethernet card.

We have found that incorrect functioning of the D-Link DE-620 range of products may have three reasons:-

THE PRINTER PORT IS INCOMPATIBLE OR NOT FUNCTIONING CORRECTLY

While the DE-620 works on 99+% of notebooks, there are some which have problems. - please check with the manufacturer of the notebook for further information.

THE DRIVERS ARE OUT OF DATE

The drivers have been updated regularly in the last 2 years to enhance compatiblity and performance. Make sure you are using the latest

THE DE-620CT CAN’T BE SET TO THE CORRECT CABLE TYPE

If this occurs you may need to reset the EEPROM using SETUP620 /F option.

THE ADAPTER IS FAULTY

Occasionally a DE-620 has a definite problem. In this instance, contact D-Link or your dealer as stated above.

DE-621 DUPLEXER

This optional product allows printing to a local printer alongside the DE-620 adapter. It is important to use the latest drivers for the DE-620 and not those that were shipped with the DE-621.

USING WINDOWS 3.1x WITH THE DE-620 ADAPTER

Microsoft have published notes on using Windows as follows:

‘Device Contention Errors with Parallel Port Network Cards Article ID: Q90926

SYMPTOMS

If you use Windows for Workgroups with a network interface card (NIC) that plugs into the parallel port, device contention errors may occur. (Only two supported NICs plug into the parallel port: the Xircom Pocket Ethernet I and II.)

CAUSE

These errors occur because Windows for Workgroups sees the LPT port as being used by two different resources: the network and the printer.
