EVP380 Communication Protocols: RS-232 and TCP/IP Configuration

The EVP380 player is designed to communicate with other devices using two distinct protocols: RS-232 and TCP/IP.

In RS-232, communication is bidirectional, allowing data exchange in both directions.

In contrast, with TCP/IP, communication is inbound-only, meaning the player can only receive commands via port 65079.

Default Addressing and Configuration

By default, all EVP380 players are configured with the address 0x80. For a command to be interpreted by all connected players, the first byte of the command must be set to 0x80. It is also possible to customize each player's address so that it only responds to messages specifically intended for it.

Input Protocol Features

The input protocol allows the player to receive external instructions, such as starting the playback of a folder or changing subtitles. In an environment where multiple players share the same connection, each device responds either to its own identifier (ID) or to a general command intended for the entire network.

Reception Protocol Structure

The reception protocol is based on a minimum frame of 3 bytes. The communication parameters are as follows:

• Baud Rate: Variable, from 1200 to 115200 baud.
• Start Bits: 1.
• Data Bits: 8.
• Parity Bits: 0 (no parity bit is used).
• Stop Bits: 1.
• Handshake: No flow control mechanism is applied.

The baud rate can be adjusted directly from the player's menu by following the path: System Settings > Serial Port.

Byte Representation
A byte consists of 8 bits, labeled from b7 to b0. For example, a byte can be represented in two ways:
    In binary: 10000000b.
    In hexadecimal: 80h.
