Cabling the Site
Standard Ethernet Connection
The transceiver cable must not exceed the maximum distances listed in Table 3-2.
10BaseT Ethernet Connection
The 10BaseT Ethernet installation must conform to the following configuration
rules:
• The twisted-pair cable must not exceed the maximum distance listed in
Table 3-2.
• No other signal should be used in the same cable sheath. For example, voice
and data signals cannot be run within the same sheath.
• Unshielded twisted-pair cable must remain at least 30.48 cm (12 in) from any
type of high-voltage power device or electrical noise source.
ThinWire Ethernet Connection
The ThinWire cable segment must conform to the following configuration rules:
• The maximum cable segment length must not exceed 185 m (606 ft).
• There must be a 50-ohm terminator at each end of the cable segment.
• There must be only one ground per cable segment.
• There must be at least 0.5 m (19 in) between T-connectors.
• The maximum number of stations, between terminators, must not exceed 30
stations.
• ThinWire cable segments must not be configured in a loop.
• ThinWire cable segments must not have any branch segments.
Do not use structured building wiring or bundled type breakout cables at baud
rates above 38.4 K. Separate point to point cables are recommended at baud rates
above 38.4 K.
