- simultaneous data transfer over one channel and control, status or clock signals over the rest of channels. Multiplexer can work without any setting. Operation principles Multiplexer asociates following serial channels to one pair of fibers: Interface / model E246 E247 E248 E249 E24A E24B Number of RS232 Number of RS422 The data rate in one channel is absolutely independent on other channels and the data rate can be any range from zero to maximum 230 000 kbps. -

ELOE246,7,8,9,A,BZKE001 RS232 interface There are three different ways how to use the multiplexer ELO E246, E247 or E248 with RS232 interfaces: 1 - Four independent duplex channels with RS232 interface. Firs with signals TxD1 and RxD1 (contacts 6,1), second with signals TxD2, RxD2 (contacts 7,2), third TxD3, RxD3 (contacts 8,3) and fourth TxD4 and RxD4 (contacts 9,4). -
Page 5: Rs422 Interface
Two multiplexers interconnection The optic cable is connected through the SC connector (models E247, E249, E24A, E24B), or ST one (models E246, 249). The remote multiplexer’s transmitter must be connected to local receiver and remote receiver must be connected to local transmitter (the fibers are crossing). -
