DES-1008M User’s Guide
NOTES: You do not need to turn off the Switch when making network connections; just plug in the cables into the ports.
When terminating a port, use either the on- board termination or a 50-ohm BNC terminator. DO NOT use both as this will cause network errors.
Follow these steps to make thin coaxial attachments to the Switch,
1.Depending on the number of BNC attachments you want to create, install the appropriate number of DES-108C modules into the Switch. Note that each module provides two switched BNC ports. For information on the installation procedure, see the Port Module Installation section of Chapter 3, Installation.
2.Obtain a thin coaxial cable. Ensure that the total cable length does not exceed 185 meters.
3.Select a BNC port to connect the node.
4.Connect a T-connector to the selected port.
5.Connect the T-connector to the thin coaxial cable. If the cable terminates at the port, enable the port’s termination by sliding its respective DIP switch to the ON position, as shown in the figure below. Otherwise, leave the switch to its OFF position. The corresponding LED of the port indicates its termination status.
