WLS1 and WLS2
The wireless sensor control unit WLS1 can either transmit up to 9 signals (= 8 voltage signals and 1 supply voltage signal), or receive up to 9 signals, and output these signals onto a CAN. The WLS1 has an internal thermocouple type K amplifier TH2M for the first two signals. The WLS1 is either configured as master (= receiving unit) or as a slave (= transmitting unit) and correspondingly labeled with M or S. A 4-digit number is also written on the cover lid of the WLS1. This number can also be used as PIN for the wireless transmission.
A WLS1 connection with another WLS1 can also be used to relay the RS232 port at a fixed baud rate (up to 115200 baud). With this configuration, a signal converter and data logger SICOLOG can be remotely programmed, or its signals can be viewed.
The wireless sensor slave unit WLS2 can transmit up to 3 signals (= 2 voltage signals and 1 supply voltage signal). The WLS2 has an internal thermocouple type K amplifier for the first two signals.
