3.5. Control Inputs
The control inputs provide assignment of programmable functions like keypad-locking, change of the
direction A/B or freezing of the actual output frequency etc.
The inputs require HTL level 10 – 30 V (PNP, switching to +) and the input function can be set to
either "active LOW" or "active HIGH". A minimum pulse duration of 2 msec must be observed with all
commands applied to the control inputs.
3.6. Serial Interface
The serial RS232 interface in general may be used
for easy setup and commissioning of the units (with use of the OS32 operator software)
to change settings and parameters remotely by PC or PLC during the operation
to read out internal states and actual measuring values by PC or PLC
The subsequent drawing shows how to link the unit with a PC, using the standard
9-pin Sub-D-9 connector

3.7. USB Port
The USB port provides exactly the same range of function as the serial interface. For USB connection
you need a standard USB cable with a "Mini 5-pin" type connector on one site. Before using the USB
port it is necessary to install the driver software on the operator PC. This software is available from
the CD included to delivery, and can also be downloaded from
.
The USB driver software is named CDM 2.04.06 WHQL Certified. zip
Please refer to the appendix chapter 9.2 of this manual for more details about USB driver installation.
3.8. Impulse Outputs
Screw terminals 19 – 24 always provide all of the output signals A, /A, B, /B, Z, /Z, even when you
do not apply inverted signals or marker pulse information to the input.
The output level (5 - 30 volts) is determined by the external voltage applied to terminal 18 (COM+).
The unit uses push-pull output stages for all channels, and the maximum output frequency is 1 MHz.
Please note that neither the input frequency nor the resulting output frequency must
exceed the maximum value of 1 MHz at all times.
