Answer the following statement(s) true (T) or false (F)
1. The three switches on top of the 1756-EN2T module can be modified before or after installing the module in a chassis. 2. When a ControlLogix module with an integrated USB port is being used for the first time with a particular computer, the required USB drivers must be configured. 3. Typically, the personal computer USB driver configuration only has to be completed once. 4. When a new device is connected to a personal computer, the Found New Hardware Wizard can assist with installing driver software automatically. 5. If the switches of the 1756-EN2T are set for a specific address, this IP address can be changed in the module’s configuration window in RSLinx. 6. With the RSLinx driver configured, a RSLogix 5000 project can be downloaded from the personal computer to the ControlLogix controller by way of the 1756-EN2T’s USB port. 7. To download an RSLogix project to a ControlLogix controller, the project must be saved and closed. 8. If you have a personal computer with no standard serial port but with USB ports, and a ControlLogix controller with a traditional 9-pin D-shell serial port, direct serial communication between the personal computer and the ControlLogix controller will be very easy.
