13. The apparatus of claim 12 wherein the network adapter is a wireless network adapter and the network device is a wireless network device.

14. The apparatus of claim 12 wherein the first address and the second address are hardware addresses.

15. The apparatus of claim 12 wherein the first address and the second address are MAC addresses.

16. The apparatus of claim 12 wherein the network device is an endoscopic control device.

17. A system comprising:

a first device comprising;

a first memory;

a network adapter, the network adapter having a first address;

a first processor coupled with the memory and the network adapter, the first processor configured, in response to a user input, to set a first identifier to a first string, to set a first encryption code to a second string, and to store the first address in the first memory; and
