The following procedures will describe how to determine if the FLEX-1500 is sharing a controller with other devices. This can severely degrade the performance of the FLEX-1500 resulting is erratic keying using the internal keyer and long latency or a lag between key closure and hearing the sidetone. The reason for this is that if a lower speed device like a keyboard or mouse is connected to the same controller as the FLEX-1500, all devices on the controller will operate at the speed of the device with the lowest speed. The FLEX-1500 works optimally, especially on CW, when it is the only device on the USB controller. This USB controller can have multiple ports to connect multiple devices to it. The FLEX-1500 connects to a USB (universal serial bus) controller in your PC.
