Developing a Router with the RTR-10 Module
To create a L ON W ORKS router with the RTR-10, perform the following steps:
1. Build a router motherboard according to the specifications described in
Chapter 2, LONWORKS Router Electrical Interfaces, and the guidelines
described in Chapter 5, LONWORKS Router Design Issues. The
motherboard can be part of custom application hardware, or can be a
standalone board. Figure 27 shows a sample motherboard schematic for
a TP/XF-78 to TP/XF-1250 twisted pair router. Additional transceiver
interfaces are described in the next section.
2. Ensure that the communications parameters in the RTR-10 router are
compatible with both of the transceivers. The transceivers listed in
Table 7 are supported directly by the RTR-10 router as predefined types.
Set the transceiver ID lines to select the proper transceiver type. For
custom transceivers, modify the communications parameters as described
in Using Custom Transceivers.
3. Assemble the router, including the RTR-10 router, two transceivers, and
a motherboard.
4. Install the router on a network as described in Chapter 6, Installing a
LONWORKS Router. The network could be a development network for
initial testing, a manufacturing network for configuration during
manufacture, or a production network for field installation.
