Clear-Com HX System Frames - Manual (Page 36)

Eclipse HX-Median, Eclipse HX-Omega and Eclipse HX-Delta
To connect the EHX PC to the matrix frame, run cable from the matrix’s R-232 DB-9M serial
connector to the 9-pin serial port of the PC (see Figure 6: PC serial DB-9F to matrix frame
R-232 DB-9M connector). The maximum recommended length of the cable is
approximately 10 feet (3 meters).
Tip: If the EHX computer does not have a serial port, and only offers USB, adaptors are
generally available from computer parts suppliers.

Eclipse HX-PiCo
A DB-9F connector is used at the PC, when wiring for an Eclipse HX-PiCo serial connection.
The 3.5mm jack socket is labeled RS-232 on the front of an Eclipse HX-PiCo. Ensure that:
• The data connections of Pin 2 to jack plug tip and Pin 3 to jack plug ring are
followed.
• Pin 5 (DB-9F) goes through to the jack plug screen.
The cable will then be ready to use.
