Target Serial Device
A pair of RF Modems can be used in lieu of a serial cable to create a wireless link
between devices. The topology below illustrates a basic wireless strategy that
can be used when connecting to target devices such as automatic meter
readers, fleet management devices, remote weather stations and a host of other
applications. When building a wireless link, consider the following:
• Use the male-to-male NULL modem adapter to connect Radio2 to a
target serial device. [Figure 6] Signals crossover inside the adapter.
• To verify serial cabling is functioning properly, insert a female-to-female
NULL modem adapter in place of Radio1 and Radio2, then test
communications without the RF modems in the link.
Create a Wireless Link between Serial Devices
To Restore Defaults (DIP Switch Method):
1. Set switches 1 & 2 of the DIP Switch to their on (up)
positions and the remaining four switches to their off
(down) positions.
2. Power off (for at least one second), then on again,
the RF modem.
