The contact numbers are given as seen on the mating face of the pin connector. The fixed connector consists of two
23、 receptacles (sockets), each having a switch activated when a plug is inserted. Therefore the termination resistor Rt (120 a) of the D2B control bus is automatically provided at the terminating device at both ends of the cable. m 3YOY583 OLY5902 7TY Contact number Page 4 EN 60933-4 : 1994 Contact de
