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.

10BASE-2 Cable Specifications

The physical characteristics of the 10BASE-2 cable must meet or exceed IEEE 802.3 10BASE-2 specifications.

Cable Characteristics:

Cable type:	Stranded Coaxial RG58 (ThinNet)
Impedance:	50 Ω @ 10 MHz
Mutual Capacitance:	24 pF/ft ±20% @ 10	MHz
Maximum Cable Length:	185 meters (610 feet)
Maximum number network connections:	30
Minimum distance between connections:	0.5 meters (1.6 feet)

Terminate 10BASE-2 cable at one end using a 50 ohm terminator and at the other end using a 50 ohm terminator grounded to earth ground.

10BASE-T Cable and Connector Specifications

The physical characteristics of the 10BASE-T cable must meet or exceed IEEE

802.310BASE-T specifications.

10BASE-T 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
Attenuation	20 dB/1000’ @ 10 MHz
Differential Characteristic Impedance	100 Ω ±10% @ 10 MHz
Maximum Cable Length:	100 meters (330 feet)

10BASE-T Connector Characteristics:

The two active pairs in a 10BASE-T 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. 10BASE-T cable for unlike devices (such as hub to terminal device) must be configured as straight through; 10BASE-T cable for like devices (such as hub to hub or terminal device to terminal device) must be configured as crossover.
