Queue Manager

The Queue manager consists of two separate programs. The client program is a small C# program designed to be installed on a windows based POS System. The server is designed to be installed on a low powered computer hooked up to a monitor at the start of the customer queue line. These 2 programs are designed to allow a cashier to easily press a call button on the till to request a customer to go to their till.

Network Layout

The computers need to be on the same network, its recommended that the Queue server has a static IP or a long DHCP lease so the client will always be able to access the Queue server at the same IP address.

Network Layout

The Client are able to detect the server IP address by sending out a broadcast UDP packet. If the server is running it will respond with information saying its the server, the IP address from that response will be used for the auto-configuration of the tills IP address and port.

The Client till number is saved in the user settings, once the till has been entered once (and saved) it will remember the till number.

The server has a web-server running on port 8081 by default, clients can connect to the website by typing http://:8081 into their preferred web browser.
