11 TP-NET PROTOCOL INTRODUCTION
The TP-NET protocol lets a client device (control device) get and/or set the values of
several parameters of the EclerNet compatible devices (MIMO and MIMO SG series
digital matrices, DUO-NET PLAYER, NXA digital audio manager series, NZA amplifier
series, NPA amplifier series, etc.), like volumes, mutes, alarms, etc. It's as well available
for eMIMO1616 digital matrix, HUB series digital zoner, MIMO7272DN and
MIMO4040CDN digital matrix.
The communication with these digital audio devices can be established using Ethernet
and the UDP/IP transport protocol, always by means of the
A second option for this communication is using the RS-232 interface that some of these
compatible devices do also have (MIMO series, DUO-NET PLAYER, NXA series, etc.). In
this case, the serial connection must fulfil the following specifications:
• Baud rate: 57600 (fixed, no autonegotiation) for all the devices, except for DUO-
NET PLAYER, eMIMO1616, HUB series and MIMO4040CDN, which use 115200
baud rate)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
In case the Ecler device has an Euroblock connector for the RS-232 interface, the serial
cable wiring, from the device's connector to a standard DB9 serial interface connector,
must be the following:
The protocol is simple and direct, making it easy to read, write and modify the generated
code. It is based on messages with no begin and end delimiter: each message is self-
delimited by the UDP packet size, which is defined with a maximum of
the messages must be written in capital letters.
To let some control systems (like CRESTRON®, EXTRON®, AMX®, RTI®, VITY®,
MEDIALON®, etc.) process the messages more easily, the EclerNet device adds the
character
LF (0x0A)
to the end of each message. This way the client can buffer the
messages to process them, if it's required. The EclerNet device can also handle several
messages received in a single message packet by using the
5800
LF
delimiter.
