The RER 107 transceiver module operates as an interfacing unit between PCLTA (PC Lon Talk® adapter) card and fibre optic LONWORKS® network. It converts the data signal from PCLTA card to fibre optic signal and vice versa. The transceiver module is plugged to the SMX connector of the PCLTA card and it is designed to meet the LONMARK standard. The transceiver module is powered from the PCLTA card.
The transceiver module can be connected to glass fibre optic or plastic fibre optic LONWORKS network with communication rate 1,25 Mbits/s. The Collision Detection is supported. Collision is detected when a message is received from the fibre optic cable at the time when data is transmitted from the PCLTA. The transceiver module has a led which flashes every time a message is received from the fibre optic cable.
