Page 5: Introduction
900 MHz ISM band allows license-free use in the US and Canada. The NL900S supports all standard serial data rates for host communications from 1.2 to 115.2 kb/s. On-board data buffering and an error-correcting air protocol provide smooth data flow and simplify the task of integration with existing applications. -
Page 6: Frequency Hopping Versus Direct Sequence
Transmitting the data signal as usual, but varying the carrier frequency rapidly according to a pseudo-random pattern over a broad range of channels produces a frequency hopping spectrum system. Forms of spread spectrum - direct sequence and frequency hopping Figure 1.1.2 NL900S USER MANUAL... -

Ping times could be slower since all broadcast traffic on the network is being transmitted across the bridge (arp packets, etc). Once you are able to ping in both directions, now you can test connectivity at the application level. NL900S USER MANUAL... -
Page 16: Repeater Mode Configuration
The following describes configuring a NL900S to operate as a repeater. “This feature set is supported in serial mode only”. First, program the NL900S Radio Modem as you normally would as a Master. Change only the Destination Radio ID address to 255. This will cause the master to repeat (retransmit) any message it hears on its assigned Network ID to all slaves on the same network. - Page 17 Network 1 Network 1 Network 1 Network 1 Network 1 Network 1 Network 1 Destination Destination Destination Destination Destination Destination Destination Destination Address 4 Address 4 Address 4 Address 4 Address 3 Address 3 Address 3 Address 3 NL900S USER MANUAL...
