Functioning IP/IE60x2

The KL60x1 serial interface terminals and IP/IE60x2 modules permit a device with a serial interface (such as barcode scanners) to be connected. Data can be exchanged in half or full duplex operation with the controller, independently of the higher level bus system. The receive buffer has a size of 128 bytes, while the send buffer is 16 bytes. Data transfer between the terminal/module and the controller is organised through a handshake in the status and control bytes. The factory setting of the terminal/module is 9600 baud, 8 data bits, 1 stop bit and no parity.
