Connected to PC via the Local Communications Cable
F.2.1 Communication Connections
The ControlWave EFM communicates with the PC through the Local Port as shown in
Figures F-1 through 2B. The Local Port has been provided specifically for installation,
startup and on-site configuration and data collection.
For ControlWave EFM’s equipped with a D-type Local Port, local communications between
the ControlWave EFM and the PC is provided over a standard ControlWave null-modem
cable (see Figure F-2A). Units equipped with the circular 3-pin Local Port utilize a special
cable as illustrated in Figure F-2B.
