CONNECTION OF LOCAL RTU TO MODEL 1700 CONTROLLER
When a local RTU (Model 1708 or Model 1716) is connected to the Model 1700, the sense
of the RX and TX lines are swapped. The COR, and TxREQ remain the same. The local
RTU does not use the radio but uses the radio interface to communicate with the Model
1700. See Figure 5.
