Issue 1, July 1996 Section 1 INTRODUCTION This manual describes the setup and installation procedures for the Intraplex PT-D350 and PR- D350 AES/EBU Program Audio Modules. Experienced users may refer directly to the tables in Section 2 for configuration data.
600 ohms. It adds two bits to each sample for CRC error detection. A green Service LED stays on when the PT-D350 is powered and operating. A red Fail LED indicates hardware failure (DSP or logic circuitry malfunction).

It lights a green Data Activity LED on each channel to indicate input activity It controls the LED level indicators (calibrated the same as those on the PT-D350) It provides error mitigation based on the 2-bit CRC code in each digital sample A green Service LED stays on when the PR-D350 is powered and operating.
PR-D350 Receiver, Block Diagram Alerts/Alarms The PT-D350 and PR-D350 modules send a card-level ALARM signal to the shelf common card if the red Fail LED is lit, indicating a DSP or logic circuitry malfunction. The modules issue no card-level ALERT signals.

The AES/EBU data format includes channel status information on the audio signal being transported. This channel status information may be structured in either consumer format or professional format, as described in the following sections. The PT-D350 and PR-D350 modules support both formats.

Harris Corporation PT/PR-D350 Uncompressed Program Audio Modules Intraplex Products Issue 1, July 1996 Remote Control Interface PT/PR-D350 modules can be used under local or remote control. When under remote control, certain configuration parameters can be changed only via the RS-232 remote port on the multiplexer.
P02 = (B00000011); As you can see, there are three P codes for the PT-D350, and two for the PR-D350. Each is a number from 0 to 255, also represented as an eight-digit binary number (in parentheses). Either the decimal or the binary representation may be used for both setting and interpreting the P codes.
Intraplex Products Issue 1, July 1996 P3 controls the test tone generator on the PT-D350 and the output sample rate on the PR-D350. Whether decimal or binary, its only legal settings are 0 and 1. IMPORTANT: When using binary numbers with a SET command, they must be preceded by the letter "B", as for example:...

Harris Corporation PT/PR-D350 Uncompressed Program Audio Modules Intraplex Products Issue 1, July 1996 Section 3 INSTALLATION PROCEDURE Refer to the figures and tables in the previous section as necessary during this procedure. Power supply and time slot considerations may affect the installation of this module into an existing multiplexer shelf.

TESTING AND TROUBLESHOOTING Transmission Line Testing The PT-D350 module contains a test signal generator that inserts a 1004 Hz sine wave tone at +8.0 dBm on both channels simultaneously. This signal can be used to test the transmission line (T1, 2 MB, or other) without the need for external test equipment.
Connect an AES/EBU decoder to the output connector on the module adapter behind the PR-D350. Observe the LEDs on the PT-D350: The SRVC LED should be on, the FAIL and ERR LEDs should be off. Adjust the output level on the AES/EBU signal generator until the first three green LEVEL LEDs are on.
