The Hand Held Device (HHD) or Schlage Utility Software (SUS) will not connect to the CO200?

Make sure the lock AA batteries are good. 4.8 VDC or higher.
When in its “Active state”, the mechanical key switch can prevent USB connection. Make sure the lock key cylinder and tailpiece are properly installed.

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.
