The customer display connects through the USB hub in the monitor.

The driver allows it to communicate with the computer as a serial device. The driver setup and installation require a choice of either of two device types: virtual COM port or device name (\\.\LCLD9).

The POS application dictates which installation type to use:

• OPOS: must use the device name driver installation, plus the Logic Controls OPOS driver.
• Most non-OPOS POS systems will need the virtual COM port configuration.
• Some non-OPOS POS systems will need the device name configuration.
• The end user must determine which configuration the POS system needs.

There is also an optional true serial customer display that physically connects to a COM port. No driver is required for this device; it simply echoes any text that is sent to its COM port.

Warning

Once the device is configured and installed as a virtual COM port connection, the USB cable should remain connected to the original USB port. If the cable is disconnected, it should be reconnected to the same USB port.

If the cable is connected to another USB port, the New Hardware wizard will launch and the driver must be installed again; doing so will create a new, different COM port connection, and will require reconfiguration of the POS software to match the new COM port number.

To avoid this side affect, either reconnect to the same USB port each time the cable is unplugged or perform the removal procedure below before connecting to a new USB port.

Outline of Installation Steps

• Obtain and unzip the driver.
• Disconnect the USB cable.
• Run the customer display driver Setup (select installation type); this does not install the driver - it just initializes the file structure.
• Connect the USB cable.
• Let the New Hardware Wizard install the driver automatically.

Removing the Customer Display Driver

With USB cable connected, right-click the customer display item in the Ports section of Device Manager and select Uninstall.
