Can You Open The Homepage Of The Connected Printer; Dhcp Error; Incorrect Static Address; Is The Card Swipe Not Being Recognized By The Authentication Server - Elatec TCP3 3.0.3.1 Technical Manual

8. Troubleshooting
• Navigate to the Network page and reset the Host address to DHCP and if required return the printer
IP address to default
• Follow the steps in chapter 6 to properly configure TCP3
• Disconnect PC from Printer port of TCP3
• Reconnect the printer to TCP3
• Reconnect the Host Port
• Return the PC back to its original port
• Rerun TCP3 Config and it should successfully discover the converter

8.5.3. Can you open the homepage of the connected printer?

If the TCP3 can be discovered using TCP3 Config but the homepage of the connected printer will not open,
the most likely cause for this issue is an address conflict between the converter and the printer.
There are 2 possible scenarios which we can explore
1. DHCP error where the printer does not receive the proper address
2. Printer uses an incorrect static IP address

8.5.3.1. DHCP Error

In this scenario the DHCP server within the TCP3 is not able to sync with the printer to establish it with the
192.168.50.100 address. From the printers user interface or from a printed configuration page verify that
the printer is using IP address 192.168.50.100. If the printer is not on 192.168.50.100, confirm that the
printer is configured for DHCP.
Some printers are sensitive to the timing of events. If the printer is unable to reach the DHCP server
immediately after it powers up, the printer may stop trying to get an address after as few as 3 attempts.
Follow these steps to determine if that is the issue.
Remove power from both the printer and TCP3 devices.
Apply power to the TCP3 first and when the Busy LED lights up, apply power to the printer. If you are
now able to open the Printer Homepage change the printer DHCP configuration to a minimum of 15 DHCP
retries before it gives up.

8.5.3.2. Incorrect Static Address

The system will operate properly if the printer is configured for Static IP instead of DHCP but only if it is
configured to match the static IP address configured on the Network configuration page. Determine the
actual IP address the printer uses via a configuration page or from the printer's local user interface then
configure TCP3's Printer IP setting to use that identical address. Any other static address will fail.

8.6. Is the card swipe not being recognized by the authentication server?

If the TCP3 is unable to forward data from the card reader to the host server, the mostly likely cause
for this issue is that the TCP3 has the wrong server IP address or port configuration. Double check the
