2.4 Power Supply and Protection
The 9256 radio modem is designed to operate over a voltage range of 8-30 volts DC. The radio also
incorporates self-protection features to prevent permanent damage if over voltage, over current or reverse
polarity is applied. The radio may need to be returned for service if this occurs.
2.5 Cruise Control
The Cruise Control Configuration Tool is a simple configuration tool that allows configuration of STI
Engineering products via a Windows™ Graphical User Interface.
Figure 3: Cruise Control interface
Cruise Control communicates with an attached radio modem over a PC serial port. The serial port
configuration must match the radio’s configuration. When a radio is supplied from STI Engineering, serial
port settings are defaulted to 19200, 8N1, with no flow control.
In order to configure and monitor a local device, plug the device into the appropriate serial port and press the
connect button (
). Cruise Control will then attempt to establish a connection with the local device. More
information on using the software can be found in the Cruise Control user manual.
For more information on configuring the radio and application notes, please see section 6 on page 42.
