Wiring Diagram for More than One Bypass
Figure 10.13 shows how to wire more than one connected bypass using serial communications.
Note:
When you install the bypass at the end of the network line, set DIP switch S1 to "ON" to enable the termination resistor. Set DIP switch S1 to
"OFF" on all other bypasses.
◆
Bypass Operations by Serial Communications
Parameters will apply to the settings when the bypass is running during serial communications. This section gives
information about the available functions and their related parameters.
■
Executable Functions
A controller can do these operations with serial communications. Parameter settings (except H5-xx) do not have an
effect on the availability of these operations.
• Monitor the bypass status and operate the bypass
• Set and view parameters
• Fault Reset Procedure
