3.6. RS-232 remote control port
The rear panel RS-232 port allows serial communication between an external device and a DUO-
NET PLAYER unit. This connection uses the TP-NET protocol syntax so the external device can obtain
the value of any of the DUO-NET PLAYER parameters (using "GET" commands) and/or modify these
values ("SET" commands). Refer to the TP-NET protocol manual for more information.
The serial connection must meet the following characteristics:
Baud rate: 57600 (fixed, no auto negotiation)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
