Radio Board Interface Connector
Figure 17 shows the pin numbering detail of connector J2 on the edge of the DR-
TRC105 radio boards. Figure 17 can be used with the schematics in the last section of
this manual to design a custom application interface for the radio boards. Note that all
signal levels into and out of this connector are nominally 3 volt logic level. Attempting to
use RS232 signal levels to directly interface the radio board can damage it.
