4. Terminal Assignments and Connections

The input pulses are connected to the screw terminals X4. The unused inputs must remain
open (HTL Single Ended as opposed to HTL Differential), or possibly be completed (unused
Z-track in RS-422 or HTL Differential format). On the X4 screw terminal 9, 8, an auxiliary
voltage of + 5.5 V / 250 mA is available for the encoder supply.
Depending on the DIL switch setting, the pulses are available at the outputs of the screw
terminal X3 in HTL or RS-422 format and are independent of the connected format. In the
HTL setting, the height of the pulse level at the push-pull outputs corresponds to the input
voltage at the supply input X1.
The Control HTL inputs (reset of the internal dividers) to X2 have PNP characteristics and
must be switched against + to activate the function. The supply voltage is connected to X1.
It should be noted that all inputs and outputs refer to the same ground potential GND,
which at the same time represents the negative pole of the device supply. At any time, the
total transmission characteristics of encoder, external components and capacity of the
cable must ensure proper signals at the input terminals of the unit, with respect to the
levels, the shape and the phase displacement A/B.
