Titan Quick Start Guide - Version 0.46 16
4. Troubleshooting
1 No LED Indicators Turn On
1. Verify the auxiliary DC input is from 12 to 50 volts at the Titan input.
a. It is important to account for voltage drops in the cable.
b. The Titan reader will draw approximately 12 watts in its power up sequence. The Titan
reader will draw approximately 18 watts at full power operation at 25 degrees C.
i. The current draw will depend on the voltage at the reader input terminals
ii. The voltage drop across the supply cable will depend on the wire gauge and the
length of cable
2. If using a PoE switch, try using an auxiliary DC input
3. If using a PoE switch, ensure the switch is 802.3at compliant (PoE+)
a. Ensure your Ethernet connection cable has all four pairs of cable – required for PoE+
If using PoE, … aux
Check the voltage at the connector end
Voltage drop due to current
2 No LAN Connectivity
1. Connect a serial cable – the Titan processor reports a rich set of status and events during startup,
including events related to LAN network connectivity
2. Use the serial cable to reset the LAN connection to DHCP (default)
a. Ensure there is a DHCP server on the network
3. Alternatively, set the Titan reader to a static IP address accessible on the network
a. Transmitter Will Not Turn On
Check the “Return Loss” to each antenna(s) configured
Check the valid protocols
Valid protocols not configured
b. Antenna Detection Problems
Disconnect the antenna cable and attach a known good termination, such as Minicircuits part
number KARN-50CN+ or similar.
• If this does not detect, contact Star Systems International.
• If the known good termination does connect, examine the cable and antenna for connection
problems.
