Ethernet Card Reader Troubleshooting

The following table describes the behavior of the LED patterns when the card reader is offline and provides possible tips to fix the error.

LED Behavior	Meaning	Action
One green blink	The card reader’s network port has an Ethernet link, but does not have a valid IP address.	Verify with your IT department that a DHCP server is accessible at this network drop. Verify with your IT department that the DHCP server will assign an IP address to devices with the Vendor Class Identifier (DHCP Option 60) "Baltech Proxreader". If DHCP is not used on this network, configure the card reader with an appropriate static IP address.
Two green blinks	The card reader is attempting to connect to its configured host or has not been added to the system.	If this light pattern continues after 60 seconds, verify the system configuration and manually add the card reader, if required.
One red blink	The card reader cannot detect an Ethernet link on either of its ports.	Verify that the Ethernet cable is connected. Verify that the card reader’s Network port is configured with a rate and duplex setting that is compatible with its network. The card reader auto-negotiates by default, but this process is not successful on certain networks with fixed rate and duplex requirements.
Two red blinks	The card reader automatically discovered the printer and its host server, but was unable to connect to the system.	Add and configure the card reader to the system manually.
Three red blinks	The card reader cannot connect to its configured host, the host servers might be down, or there is a network problem.	Verify the host and network operation, then disconnect and reconnect the card reader to reset.
Four red blinks	The card reader has detected that the IP address assigned to it is already in use by another device on the network.	Contact your IT department to identify the device with the same IP address. Change the IP address of the card reader or the conflicting device. If no change was required to the card reader’s IP address, then disconnect and reconnect the card reader to reset.
Red and green blink	The card reader is in maintenance mode.	Move the network cable from the card reader’s Printer port to its network port to restore normal operations.
