Axis 241Q 4 port encoder. This unit was recently removed from a site when all of the cameras were upgraded to IP, and is in fully functioning condition. All units are tested before shipping. Refunds are not accepted for this item, defective units can be returned for a replacement. IP address and username information was not documented for this encoder, so it is recommended to default all the unit back to factory default settings before using. This can be completed by first powering down the unit. Next press and hold the control button located just above the status LED's with a paper clip. While keeping the button held, apply power to the unit. Continue to hold the control button for 30 seconds after the blade powers on, then release. The blade will now default to an IP address of 192.168.0.90, username of root, and password of pass.
