| + | ==== Save and Reset ==== | ||
| + | Before changes to communication slots become active, you need to save them to the LAN Bridge by pressing the 'Save' button next to the relevant sections of System Commander.\\ | ||
| + | You will also need to reset the LAN Bridge for communication slot changes to become active. | ||
| + | |||
| + | After the changes are saved and the LAN Bridge has been reset, the last step is to change the configuration on your TCP Clients (iPads, etc) to communicate to the LAN Bridge instead of directly to the target device.\\ | ||
| + | In this example, the iPads would be changed to communicate to the IP of the LAN Bridge on TCP port 10004. | ||
| + | |||
| + | Now you can have multiple devices connecting and communicating with a single TCP Server at once, bypassing and single connection limitations of the target device. | ||
