The polarity of the supply voltage selects the transmission channel of the transmitter:
• VIN1 = +24 V, VIN2 = 0 V: transmission channel C1
• VIN1 = 0 V, VIN2 = +24 V: transmission channel C2
The wiring of pin 4 determines the transmitting power and thereby the range:
• Pin 4 = +24 V: standard range
• Pin 4 = 0 V or open: reduced range
