LEDs
The green LED shows that the unit is ready (power supply switched on).
The yellow LED shows an input error in case of a static illumination. (only with RS-422 or HTL
differential), otherwise it flashes.
DIL Switch
The DIL switch S1 is used to detect an input error with HTL differential or RS-422 format. The A line
can be monitored via DIL1/1. If the DIL switch DIL1/1 is set to ON, the A line can give out an error.
The same applies to DIL switch DIL1/2 and the B line, as well as DIL1/3 and the Z line.
The DIL switch 2/1 is used to switch the voltage level of the encoder output at X6 from 5V (OFF) to
24V (ON). The DIL switch 2/3 is used for loading the factory parameters when the supply voltage is
switched on. In the ON position, the factory parameters will be loaded at the next power up and the
programmed values will be overwritten.
USB
The USB port can be used to connect to a PC. With the help of OS this interface can be used as a
programming interface. The ground isolated interface is configured as a virtual port and works with
the LECOM protocol with 115,2 kBaud, 8N1.
RS-485
An RS-485 (2-wire) interface is available at X5. Terminal 2 of X5 provides the non-inverted driver
output or input (A/Y), whereas terminal 3 provides the inverted driver output or input (B/Z).
This interface works with the LECOM protocol by default and can be switched to the MODBUS
protocol by parameter setting using the USB port and OS.
