Claim:
A method of facilitating replacement of an auxiliary device associated with a weapon: facilitating mounting the auxiliary device to the weapon at a first fixed distance from a remote control device configured to control the auxiliary device; facilitating keying said remote control device to the auxiliary device to establish bi-directional wireless communication between said remote control device and the auxiliary device comprising: initiating an exchange of a unique device code and a synchronization count between said remote control device and the auxiliary device, said unique device code being different from any key codes associated with other auxiliary devices mounted to other weapons to avoid control of one or more of said other auxiliary devices by said remote control device; enabling an update of said synchronization count in said remote control device and said auxiliary device upon each transmission between said remote control device and the auxiliary device; facilitating mounting a replacement auxiliary device to the weapon at a second fixed distance from said remote control device in place of the auxiliary device, said remote control device being configured to control said replacement auxiliary device; and facilitating keying said remote control device to said replacement auxiliary device to establish bi-directional wireless communication between said remote control device and said replacement auxiliary device comprising: initiating exchange of a second unique device code different from said first unique device code and a second synchronization count between said remote control device and said replacement auxiliary device, said second unique device code being different from any key codes associated with said other auxiliary devices mounted to said other weapons to avoid control of one or more of said other auxiliary devices by said remote control device; and enabling an update of said second synchronization count in said remote control device and said replacement auxiliary device upon each transmission between said remote control and said replacement auxiliary device.
