  • Page 8: Device Setup

    To be able to configure the DLS-C(H)/FLS-C(H), it must be powered and connected to a PC. Figure 2 shows the necessary connections. On the PC, any terminal program can be used to communicate with the module. A configuration utility is also available on the web page www.dimetix.com. DLS-C(H)

  • Page 9: Controlled Mode

    Host software is required for operation of the DLS-C(H)/FLS-C(H) in controlled mode. When connecting multiple devices to a single serial line (RS422), strict Master-Slave communication must be implemented (DLS-C(H)/FLS-C(H) operates as slave). For software sample-code or application-notes please consult our web site www.dimetix.com. Careful testing of the host software together with the devices prior to installation is strongly recommended.
