Connecting to cabinets
―
Connect SNOW-1703U to an external device, and then connect it to IFH or IFH-D devices.
―
Connecting parts may differ in different products.
• Do not connect the power cable before connecting all other cables.
Ensure you connect a source device first before connecting the power cable.
• Before connecting power to the cabinets, connect the I/G card to the cabinets first.
• One SNOW-1703U supports only one type of LED pitch cabinets. Do not connect different
types of LED pitch cabinets.
― Connecting other types of cabinets may cause abnormal image quality.
• After connecting the HDBT cable, connect the OCM cable in the following order:

― Make sure that the HDBT cable length is from 15 m to 100 m.
― If you use a cable that is out of specified length range, the signal quality may be unstable.
• Use the LAN cables recommended on the
HDBaseT
website (http://hdbaset.org/hdbaset-
