GPI/RLY Interface Connector
The RJ-45 socket labeled GPI/RLY Interface connects the CPU
card to a GPI-6 or RLY-6 card. The GPI-6 provides six general-
purpose opto-isolated logic inputs. The RLY-6 card provides six
single-pole, double-throw relay outputs.
Both card types mount in either an IMF-3 interface frame or an
IMF-102 interface frame. Up to ten GPI-6 or RLY-6 cards can be
operated at one time from the matrix by daisy-chaining the
cards together. Each card has an IN and an OUT connector for
this purpose.
The RLY-6 and GPI-6 cards connect to the GPI/RLY interface
connector using shielded category-5 cable. For more information
about the GPI-6 and RLY-6 cards, consult their respective
manuals in the Eclipse HX documentation set.
Clear-Com recommends the use of shielded cable.
For wiring pinout information for GPI/RLY interfaces, see:
• The Relay Interface Module (RLY-6) Instruction
Manual.
• The General Purpose Inputs (GPI-6) Instruction
Manual.
RS-232 DB-9 Connector
The DB-9 connector labeled RS-232 connects the Eclipse HX-
Delta matrix to an external computer. To connect a computer to
the matrix, run cable from the RS-232 connector to the PC’s
serial port. The maximum recommended length of the cable is
approximately 10 feet (3 meters). A computer has either a 9-pin
serial port or a 25-pin serial port.
