Horner XL4 Establishing Communication

We program the Horner XL4 OCS all-in-one controller by using Cscape. We will now use our Cscape software to establish communication. Last time we customized Cscape with icons to make it easier to find, communicate and control the unit. There are two different ways to communicate to the XL4 OCS controller, Ethernet and Serial. There are several different methods within these two ways that the XL4 will communicate. The Cscape software package will communicate both of these ways. We will look at establishing communication using Ethernet, USB (Serial) and Serial RS232.Another two serial ways to communicate would be RS485/RS422 (Serial) and CAN Bus (Serial). These two methods allow multiple controllers connected to the communication network. This is similar to Ethernet. Continue Reading!
