Connections
4.1 Router communication
You gain access to router for comm
unication purposes by connecting either the router’s
serial port to your computer and/or by using an Ethernet connection.
When multiple SL-D32P+ is connected together to make a bigger matrix, it is
not necessary to connect to more the one device at a time. The commands are
automatically distributed to all the devices.
4.1.1 Serial connection
Connection can be made through the serial port of the router; see also Chapters 2.4 and
2.5 for connection details.
The communication parameters are configurable. Please refer to the protocol
documentation of the appropriate communication/control protocol.
Example: The protocol parameters of the VikinX Compact routers are as follows:
Bit rate 19200 bit/s
Data bits 8 bits
Stop bits 1
Parity: No parity
For further details concerning this protocol, please refer to the following manual:
The DE9 female socket for the serial port of the router has the following pin-out:

Note that if the standard RS-232 cable specification (DCE) is followed:
A cable with Male+Male or Female+Female connectors at the cable ends is
used for Rx/Tx crossed connection, and
A cable with Male+Female connectors at the cable ends is used for a straight
through connection.
4.1.1.1 Maximum cable length (RS-232)
IEEE has specified the maximum cable length for an RS-232 connection to 15m. Longer
distances can be installed depending on the environmental conditions of the installation
site.
It is the responsibility of the installer / user to secure a proper installation of the
RS-232 connection.
