ID-AL My Video Player - VP320 and VP330 - Quick Start Guide V1.0
11.2 RS-232 Serial Link
This link allows the player to receive commands, to send arbitrary frames, and to send status information. By
default, it is configured as follows (can be changed in the setup menu):
Baud Rate (bauds) Start Bit(s) Data Bit(s) Parity Bit(s) Stop Bit(s) Handshake

In reception, the player obeys a control protocol also used over TCP/IP. See the chapter RS-232 and TCP/IP
Control Protocol.
•
Arbitrary frames can be sent with the
[RSSxxx]
and
[RSExxx]
tags. These frames must be defined in the
serial.txt
file in the
SYSTEM
folder of the storage device, as
#xxx:tt tt tt…
, with one definition per
line (e.g.:
#002:98 75 21 35 45 B2
).
11.3 RS-232 and TCP/IP Control Protocol
The control protocol allows the player to receive commands and information requests. It can be used either over
RS-232 or over TCP/IP port 65079. It is based on a 3-byte frame: “Status”, “Command”, and “Data”:
