Figure 2-6. Full-duplex and Half-duplex Cable
Use the half-duplex cable (shown in the bottom part of Figure 2-6)
when connecting the ControlWave Express to another ControlWave
series unit (again, with the exception of the CW_10/30/35).
When communicating with a Network 3000 series RTU 3305, RTU
3310, DPC 3330, or DPC 3335 or CW_10/30/35, you must use one of
the cables shown in Figure 2-7.
