Developing a Router with the RTR-10 Module

To create a LONWORKS 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.
