SJ Research Econet Clock Sockets
The SJ Research Econet Clock has an integral power supply (see top picture). When the box is open the switches used to set the network speed are clearly shown in the middle of the circuit board (see middle picture). The two Econet sockets can be seen at the right hand end of the box. The Clock is usually connected in the middle of a network using a split socket box. Each socket connects to one half of the network and the two halves are connected by the socket box.
