External Amplifier Unit I/O
The following functions are allocated to the external I/O lines.
Note 1. Use a separate stabilized power supply for the Amplifier Unit, particu-
larly when high resolution is required.
2. Wire the Unit correctly. Incorrect wiring may result in damage to the
Unit. (Do not allow the I/O lines, particularly the linear output, to come
into contact with other lines.)
3. Use the 0-V ground line (blue line) for the power supply and use the
shield wire (linear output ground) together with the linear output (black
line) for linear output. Each of these grounds must be used for the
designed purpose. When not using the linear output, connect the lin-
ear output ground to the 0-V ground line.
Refer to 3-2 Hardware Functions for I/O functions.
