•Five BNC type connectors, corresponding to channel B input and outputs.
•Five BNC type connectors, corresponding to channel A input and outputs.
•One opening for an optional fiber-optic input connector (Option 01). If not used, it is covered
by a plastic hole plug.
•Option 07 provides an IEC-320 power inlet connector with fuse compartment. Options 08 or
10 provide a 3-pole terminal strip and separate fuse holder.
Option 01 – Fiber Optic Input
Option 01 provides an 820 nm, Type ST optical fiber input for channel A. Channels B and C may
also be driven from the Option 01 fiber optic input. If your 1073A came with Option 01 installed,
only Channel A outputs will be driven by the fiber optic input. To configure Channels B and
C outputs to be driven from Option 01 fiber optic input, move jumpers JMP9 and JMP16 from
position A to position B. All 12 output channels will then receive the same input signal as provided
by Option 01. If you need to configure these differently, please consult the operation manual.
Option 04 – On/Off Switch
Use the On/Off switch to power on the Model 1073A. If your 1073A does not have a On/Off switch
the unit will be powered on when you connect power to the inlet connector.
Energizing the 1073A
Before connecting voltages to the clock, make sure to read the power inlet label to verify the correct
voltage. Make sure that the voltage you are connecting is in the correct range supplied on the label.
The figures shown below indicate the three types of inlet supply connectors available. For Option
07, a fuse is located behind a snap-fit latch on the right side of the connector. For Options 08 and
10, a fuse is located to the right of each power inlet terminals.
