Serial Interface and Line Settings
The main line settings for this serial interface are:
•
Asynchronous data transfer
•
1 start bit (logic "0")
•
7 data bits (LSB first on line)
•
Even parity
•
1 stop bit (logic "1")
•
4800, 9600, 19200, 38400, 57600 or 115200 baud
To set the serial interface baudrate choose:
> Unit > Setup > Serial port settings.
There is no flow control on the serial interface. Apart from correctly formatted
messages, the only significant character here is the SYNC-character (value 16
hex). The device sends this character to indicate that it is busy executing the
command and preparing the response. This prevents other devices from taking
control of the bus if the response cannot be given immediately.

RMCP over Ethernet
You can send RMCP commands to the device using the Ethernet interface. The
commands are sent as data in a TCP/IP stream. The used socket number is
5933.The RMCP protocol is exactly the same as for the serial interface, with one
small exception: the receiving device ignores the RMCP address of the device (that
is present in an RMCP command).
To enable the device to communicate over Ethernet, the Ethernet interface needs
to be configured. See:
>> Unit >> Setup >> Ethernet settings
