Compliance Information
UL Listed
C-UL Listed (Canada)
CISPR/EN55022 Class A

FCC Regulations

This equipment has been tested and found to comply with the limits for a class
A digital device, pursuant to part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user
will be required to correct the interference at the user’s own expense.

Canadian Regulations

This digital apparatus does not exceed the Class A limits for radio noise for
digital apparatus set out on the radio interference regulations of the Canadian
Department of Communications.

European Regulations
Warning

This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.

Maximum Cable Length

: 185 meters (610 feet)

Maximum number network connections:30
Minimum distance between connections: 0.5 meters (1.6 feet)

Terminate 10Base2 cable at one end using a 50 ohm terminator and at the
other end using a 50 ohm terminator grounded to earth ground.

10BaseT Cable and Connector Specifications

The physical characteristics of the 10BaseT cable must meet or exceed IEEE 802.3
10BaseT specifications.

10BaseT Cable Characteristics:

Category 3 wire or better is required; category 5 wire is recommended. Either
shielded twisted pair (STP) or unshielded twisted pair (UTP) can be used. DO
NOT USE FLAT OR SILVER SATIN WIRE.

Category 3:

Gauge 24 to 22 AWG
Attenuation 28 dB/1000’ @ 10 MHz
Differential Characteristic Impedance 100 Ω ±10% @ 10 MHz

Category 5:

Gauge 24 to 22 AWG

Differential Characteristic Impedance 100 Ω ±10% @ 10 MHz

Maximum Cable Length: 100 meters (330 feet)

10BaseT Connector Characteristics:

The two active pairs in a 10BaseT network are pins 1 & 2 and pins 3 & 6. Use
only dedicated wire pairs (such as blue/white & white/blue, orange/white &
white/orange) for the active pins. 10BaseT cable for unlike devices (such as
hub to terminal device) must be configured as straight through; 10BaseT cable
for like devices (such as hub to hub or terminal device to terminal device) must
be configured as crossover.
