Figure 4 - Radio Board Transmit Power Adjustment
Radio Board Interface Connector
Figure 5 shows the pin numbering detail of connector J2 on the edge of the DR-TRC103
radio boards. Figure 5 can be used with the schematics in the last section of this
manual to design an application interface for the radio boards. Note that all signal levels
into and out of this connector are nominally 3 V logic level. Attempting to use RS232
signal levels to directly interface the radio board can damage it.
