R70SR SNAP SIGNAL™ Serial Data Radio



Configure the DIP Switches

Before changing DIP switch positions, disconnect the power

(1)

. Any changes made to the DIP switches are not recognized until after power is 

cycled to the device. For parameters not set using the DIP switches, use the configuration software to make configuration changes. For para­

meters set using the DIP switches, the DIP switch positions override any changes made using the configuration software.

If the cover is in the locked position, the arrow on the cover is above the notch on the base. Follow these steps to unlock and remove the 
cover. 

Serial Mode vs MultiHop Mode for R70SR Data Radios

As of early 2023, the R70SR Serial Data Radio firmware allows the radio to be configured as either a serial data radio or a MultiHop data ra­
dio that is compatible with other Banner Sure Cross MultiHop data radios. These updated R70SR serial data radios also contain an addition­

al ID label on the device to assist with MultiHop site surveys. Ignore this label when your radio is operating in serial data radio mode. R70SR 

serial data radios manufactured before date code xxxx have different DIP switch configurations. Please refer to datasheet 

224673

 for the 

legacy R70SR model instructions. 

Serial Mode--Serial Mode provides the simplest setup and best performance for point-to-point networks and small star networks. Serial mode 
is not ideal for medium to large Star or Tree topologies because the client radio broadcasts all messages and does not build a routing table. 

This results in slower communication, which is ideal for simple cable replacement applications. There is no need to adjust the Modbus ad­
dress of connected devices, resulting in a simpler set­up process. 

MultiHop Data Radio Mode

­­MultiHop Data Radio mode requires more configuration but allows for much larger Star and Tree topologies be­

cause the client radio builds a routing table to more efficiently communicate with each server device on the network. Configuring your data 

radio as a MultiHop radio adds the ability to perform a site survey analysis with the MultiHop Configuration Software, offers improved perfor­

mance in larger Star and Tree network topologies, and adds the ability to communicate with other Sure Cross MultiHop data radios including 

the MutliHop DXM Wireless Controllers.

Baud Rate and Parity

— The baud rate and parity are set to default at 19200; no parity. These settings are not configurable via the DIP 

switches and must be changed using AT commands. These settings must match the device wired to the radio's serial port. A faster baud rate 

setting may improve system response time. Changing the baud rate does NOT change the radio transmission rate. The software default also 
provides the ability to set custom baud rate and timing parameter settings via AT commands. For more information, see the technical 

note

 (p/n b_51173725). 

Serial Routed Mode

—Use routed messaging when using a point­to­point or point­to­point­with­repeater topology. Routing is more robust and 

faster than broadcast messaging. In routed mode, the radios will route serial data packets only to a single device. In general, this mode is for 
faster communications. If the server radios are in routed mode, they will only route serial data packets to the client radio and will only listen 
for serial data packets coming from the client. If the client radio is in routed mode, it will only route serial data packets to the first server radio 

that comes into the network. The client radio should only be in routed mode if used in a point­to­point network. 

Rotate the cover counterclockwise so that the notches are aligned together.
