Troubleshooting Table A-1 Troubleshooting Solutions Symptom There is no power. The encoder does not start up normally after turning on the power. The STATUS indicator is blinking (BLINKING TEMPERATURE WARNING). The STATUS indicator continues to blink after turning off the power and leaving the unit for a while. Network Troubles The STATUS indicator on the front panel does not light. The encoder and the decoder are not communicating. It is impossible to access the setting pages though pictures can be displayed. Possible Cause • The power cord may not be connected correctly. • The power plug may not be firmly plugged into an outlet. • An IP address may not have been correctly assigned from the DHCP server. • The temperature inside the encoder may be beyond the specified temperature. • The ventilation openings or the cooling fan slots could be blocked. The cooling fan may be damaged. • The ethernet cable may not be connected to the Ethernet port (100BASE-TX). • The correct cable may not be used. • The pins inside the connector may not be connecting or may be shorting out. • The cable length per segment may be longer than the recommended cable length. There could be a problem with the subnet masks. • The default gate is incorrectly set. It is necessary to correctly set the default gateway to access from different networks (subnets). • The gateway address is incorrect. It should be assigned based on the IP address of the encoder. Possible Solution Firmly insert the power plug firmly into the outlet. • Confirm that the DHCP server is running correctly. • Remove anything from around the ventilation openings and cooling fan slots. Contact your dealer. • Firmly insert the cable until you hear a click. • Use the straight cable when connecting the unit to a switching hub or router. Use the cross cable when cascading two switching hubs. When using a switching hub with the cascading port, refer to the operating instructions of the switching hub. • Check the pins. • Use network cables that are appropriate for the transmission speed and that are shorter than 100 m. • If the encoder and decoder are in the same network, then they should have the same subnet mask. • If the encoder and decoder are in different networks, then the should not have the same subnet mask. • Refer to the network administrator for the default gateway address and confirm that the settings on the NETWORK page of the decoder have been set correctly. • Refer to the network administrator and perform the settings. 78
