4. Installation Tips
There are two external power sources required for
Optical Unit supply.
An external +5V and -5V DC power sources with
±2.5% output tolerance are required for Optical Unit
supply. The operating current must be not less than 7.5
mA.
The power supplies are to be connected to pins X1/1
and X1/2.
They are necessary for supply of:
The power supply for customer external electronics
depends on scheme concepts. But one must take into
account that the total current consumption of Light
Emitters and TE Cooler of DX6106 Optical Unit is not
more than 300 mA at 0 -5 C operating temperature of
TE coolers.
For proper Optical Unit operation the ground line
should be separated into three wires and joined in the
one, close to power supply common terminal.
Shielding ground should be in contact with the Optical
Unit housing.
The recommended connection is shown in Fig. 4.1.
