CONNECTING THE LINE INTERFACE FOR LB200A-R4
1. To function properly, the two LB200A-R4s must be connected together using twisted-pair, uncondi-
tioned, dry, metal wire, between 19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through
signal equalization equipment are not acceptable.
2. The LB200A-R4 is equipped with an RJ-45 interface jack (
Figure 3
)
The RJ-45 connector on the LB200A-R4’s twisted pair interface is polarity insensitive and is wired for a two-
wire interface. The signal/pin relationship is shown in
Figure 3

CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
CAUTION
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
The RJ-45 ports labeled
Eth 0 and Eth 1
are Auto-MDIX 10/100Base-T interfaces. These ports are
designed to connect directly to a 10/100Base-T device or network.
Figure 4
shows the signal/pin relation-
ships on this interface. You may connect this port to a hub or PC using a straight through or crossover cable
that is up to 328 ft long.
