Connecting the Network Cables
Before you connect the Savi fixed reader’s network cables, check relevant
configuration or wiring diagrams.
Note: The Savi Fixed Reader SR-650-101 is rated for use in severe
environments. For additional precautions, Savi recommends the use of
heat shrink tubing (Savi part number 680-02423-001) for units subject
to outdoor use.
You can connect the Savi fixed reader using two types of network
protocols:
◆ SaviNet connection (RS-485)
◆ Ethernet via RJ-45 connector; 10Base-T
SaviNet Connection (RS-485)
SaviNet requires an 8-foot (2.4 meters) network cable with an RS-485 to
RS-232 converter on one end and an RS-485 connector on the other end
to connect the Savi Fixed Reader SR-650-101 to the host computer.
With a SaviNet connection, you can:
◆ Connect one reader directly to a host computer
◆ Attach multiple readers in a daisy chain pattern
Connecting to the Host Computer
To directly connect the Savi Fixed Reader SR-650-101 to the host computer
using the RS-485 port:
1. If you are installing the Savi fixed reader in an outdoor location, slide
heat shrink tubing onto the network cable before connecting the cable to
the reader.
For detailed instructions regarding application of the heat shrink tubing,
follow the procedures in Appendix B.
2. Plug the SaviNet cable’s RS-485 female connector into the
NETWORK IN port on the Savi fixed reader. Ensure that the notch is
correctly aligned. See Figure 2-3.
