Make sure the mechanical triangles on the back of the outside escutcheon are aligned properly. See the installation instructions at www.schlage.com/support Schlage Technical Support. Or go directly here - CO Series Installation
If the mechanical alignment triangles on the back of the outside escutcheon are not aligned, the CO200 or CO250 will not connect with the SUS/HHD. Ensure these triangles are in alignment.
If the Schlage Utility Software pops up a "E201 error", just ignore it, and tap "Device Options" or update your firmware. See 78451
Make sure the HHD/SUS is set to USB communication by checking the small icon right of the "No Device Connected" message. The symbol should be a USB symbol when working with USB enable products. See the picture included here.
If a Serial (9-PIN D-Type) symbol is shown, the HHD is set for serial communication. This mode is used when working with Legacy products that require a serial connection
Just tap on the symbol to switch between USB and Serial HHD communication methods.
