    The commands can be executed via the remote CLI of LASAL Class 2 or a direct input on the device. CAUTION: If data are not first before, the terminal settings are lost. 2. Disconnect the ETT 771 supply. 3. Loosen the battery cover screws with a cross-head screw driver and remove cover.

  • Page 21: Wiring Guidelines

    BUILD-IN TOUCH TERMINAL ETT 771 Wiring Guidelines Ground The terminal must be connected to ground through the assembly on the control cabinet or over the connection provided. It is important to create a low-ohm ground connection, only then can error-free operation be guaranteed. The ground connection should have a maxi- mum cross section and the largest (electrical) surface possible.
  • Page 22 ETT 771 BUILD-IN TOUCH TERMINAL RS485 • Because the RS485 requires a defined quiescent point, a pull-up and pull-down resistor is required in addition to the termination resistor. The resistors are already implement- ed in the device. • The 120 Ω terminating resistors must be placed at each bus end.

  • Page 23: Can Bus Setup

    BUILD-IN TOUCH TERMINAL ETT 771 CAN Bus Setup This section explains how to correctly configure the CAN bus. The following parameters must first be set: Station number and data transfer rate. CAN Bus Station Number Each CAN bus station is assigned its own station number. With this station number, data can be exchanged with other stations connected to the bus.

  • Page 24: Can Bus Termination

    ETT 771 BUILD-IN TOUCH TERMINAL CAN Bus Termination In a CAN bus system, both end modules must be terminated. This is necessary to avoid transmission errors caused by reflections in the line. The termination is made by an internal 120 Ω resistor between CAN A (LOW) and CAN B (HIGH).
