C-BUS NETWORK PARAMETERS (CONTINUED)

Maximum 34 V DC on the C-Bus cable: 2,000 mA (2 A)

Each DIN Relay and DIN Dimmer with an on-board network Power Supply can

supply 200 mA to the Bus. Where more than 10 DIN Relays and/or Dimmers are

required on a network, the additional units should be the type without an

on-board network Power Supply.

Maximum number of Network Burdens: One (only one)

The PCI, USB, Ethernet Network Interface, and Network Bridge come with a

plug-in RJ-45 Hardware Burden. We recommend using the Hardware Burden.

A software-enabled Network Burden is available on DIN units and Professional

Dimmer units. (Software Burdens are disabled by default.)

Minimum number of active System Clocks: One active, two more enabled

System Clocks are available on any DIN unit or Professional Dimmer unit. Use

the Toolkit software to enable a Clock, except on the PC Interface, where it is

enabled by default. Recommended maximum three enabled Clocks at any time.

Maximum number of networks than can be linked together: 255

Topologies: Single- and Multi-Network: Star, Daisy Chain, or Star-Daisy Chain

combination.

Maximum 6 Network Bridges (7 networks) on a Daisy Chain.

C-BUS DATA CONNECTIONS

C-Bus units can have RJ-45 style ports for any of four types of data:

C-Bus network•

RS-232 Serial•

USB•

Ethernet•

Verify that you are connecting the correct cable at each port. Each cable carries

a different type of signal, and incorrect connections could result in damage to the

equipment, a computer, and/or the C-Bus network.

CAUTION

HAZARD OF IMPROPER OR UNSTABLE OPERATION

Verify that all connections to C-Bus units are being made to the correct port. •

Only connect an RS-232 Serial cable to a port labeled RS-232; an Ethernet cable to a port •

labeled Ethernet; and a C-Bus network cable to a port labeled C-Bus.

Failure to follow these instructions can result in improper C-Bus network operation,

damage to the computer or C-Bus network equipment, or both.

Network Connection Types

C-Bus: The C-Bus network consists of C-Bus units interconnected with Cat-5 •

UTP cable. C-Bus network connections are typically made to labeled RJ-45

ports at the bottom of the unit or to screw terminals.

RS-232 Serial: The standard PC Interface (SLC5500PCI) has two labeled RS-•

232 Serial ports, enabling computerized monitoring and conﬁguration of the

network. RS-232 cable is shielded untwisted wire.
