3.2.6 Router orientation
X-point commands in control protocols are using source and destination when controlling
routers. This must be mapped to ports in the router. When controlling RS-422, every port is
bi-directional and includes both a source and a destination. The mapping is different in XY
mode and ported mode.
3.2.6.1 Router orientation in ported mode
By default, the router is "destination oriented" (DIP is OFF). A bi-directional connection is
made between the two ports. If both ports are configured as dynamic, the port referred as
source will be used as a controller and the port referred as destination will be used as a
device.
When the router is "source oriented" (DIP is ON) the mapping is different. If both ports are
configured as dynamic, the port referred as source will be used as a device and the port
referred as destination will be used as a controller. This makes it possible to use a single-
bus panel to select one-of-several machines to control from a single location.
3.2.6.2 Router orientation in XY mode
In XY mode all ports are fixed; port 1-16 as controllers and port 17-32 as devices. The
control system will see the router as a 16x16 matrix.
When the router is "destination oriented" destinations 1-16 are mapped to ports 17-32 while
sources 1-16 are mapped to ports 1-16.
When the router is "source oriented" destinations 1-16 are mapped to ports 1-16 while
sources 1-16 are mapped to ports 17-32.
As in ported mode this makes it possible to use a single-bus panel to select one-of-several
machines to control from a single location.
Switch 9 on the configuration switch defines the router orientation.
SW 9 Router orientation
OFF Destination oriented
ON Source oriented
Default is OFF.
3.2.7 Future Use
Switches 10 -17 are currently not in use.
3.2.8 Ext Address
When multiple SL-D32P+ are used to make one bigger router, these DIPs are telling which
ports this router has.
SW 18 SW 19 SW 20 Ext Address Ports
OFF OFF OFF 0 1-32
OFF OFF ON 1 33-64
OFF ON OFF 2 65-96
OFF ON ON 3 92-128
Default setting is OFF/OFF/OFF.
