3.3.1 Multi-Interface Connector
The multi-interface connector is a standard 26-pin 0.1” pitch short latch IDC header with pins in two rows
of 13. Connection to this is made using a 26-way IDC without strain relief (such as AVX/Kyocera 00 8290
026 000 0X 1 or Harting 09 18 526 7803). To support legacy applications, a cable is available that
converts its pin-out to a DB25 connector with the same pin-out as the 9522A. The connector includes
four interfaces:
• DC Power
• Control/Digital Audio (DPL bus)
• RS232 Data
• Analog Audio
The pin out information for this connector is given in
Table 3 below. The pin out from the DB25 adapter is
given in
Table 4 below.
