Question
A technician is working to connect an RS-232 serial signature pad to a customer’s ultralightweight laptop. Which of the following should the technician use to install the device?
A. Port replicator
B. Wi-Fi Direct
C. Hotspot
D. USB-C cable
Answer
A. Port replicator
Explanation
An RS-232 serial signature pad uses a serial port interface, which is typically not found on modern ultralight laptops. Most ultralight laptops have minimal ports, often limited to USB and sometimes a video output port. To connect an RS-232 serial device like a signature pad, you would need a port replicator. A port replicator is an external docking station that provides additional ports, including serial ports, to connect legacy devices to laptops that lack those ports. Using a port replicator with the appropriate serial port would allow the technician to connect the RS-232 serial signature pad to the ultralight laptop.
The other options are incorrect because:
B. Wi-Fi Direct is a wireless peer-to-peer connection and cannot be used to connect a wired serial device.
C. A hotspot is a wireless access point and cannot be used to connect a wired serial device.
D. A USB-C cable would not be sufficient as it does not provide a serial port interface required by the RS-232 serial signature pad.
