WIRING TO 4-WIRE EQUIPMENT
Eclipse Pico uses a 2-pair analog wiring scheme between the matrix
and 4-wire equipment. The wiring scheme shown in Figure 4-3 below
is for 4-wire equipment with an RJ-45 connector. For 4-wire equipment
with other types of connector the pin connections should be changed
in accordance with the installation specification for the 4-wire
equipment.
2-Pair Analog
Two-pair analog wiring to 4-wire equipment is done with shielded CAT5
RJ-45 cable if CAT5 cable is used or another suitable type of cable
depending on the 4-wire equipment.
• Pair 1 is not used.
• Pair 2 transmits digital data from the 4-wire equipment back to the
matrix.
• Pair 3 transmits audio from the 4-wire equipment to the matrix.
