Sensoray Model 425 Instruction Manual Page 24
Model 425 connector J1 is used to make all electrical connections to external encoders or other pulse sources.
Such sources may be connected to an optional model 7503TDIN screw termination board, which in turn con-
nects to 425 connector J1 by means of a 26-conductor flat cable. Sources may be electrically connected and dis-
connected from the 425 or 7503TDIN without removing the 425 circuit board from the backplane.
