WARNING

: Proper grounding of the AC power outlet is necessary for personnel and

equipment safety. Use the ground stud provided on the unit and on the base frame to properly

ground the entire system.

Power Requirements

Power Consumption

• Discrete interface connections are made via (J3) connector, located at the top of each unit.

Certain connections have to be performed on the Discrete Interface connector for proper

operation (read 5 INTERFACES at page 25).

CAUTION

: Safety interlock is incorporated in the equipment.

If the Discrete Interface (J3) of one amplifier (single unit) is not intended to be used, disable

this interlock by connecting pin H with pin R at the discrete interface (J3) of each amplifier.

• Serial Interface connections are made via (J2) connectors located on the top of the each unit.

Use the cable provided to interconnect two Serial interfaces (J2) ports to the common Serial

Communication port (P1) located on the Main Frame, if RS-485 common interface is used.

Independent RS-422 interface is also supported, so each unit may be connected to one

computer via its serial interface connector (J2). Each unit has an address assigned, i.e. 0 or 1.

By selecting the proper address, communication with each unit can be established. To change

the communication addresses see Section 7.3.3 Software Configuration at page 33. Refer to

TABLE 9 at page 33 for pin assignments of Serial Interface (P1).

CAUTION:

The communications protocol for the serial interface is RS-422. To use the

standard IBM

compatible personal computer (running DOS 3.1 or higher) with an RS-232

serial port, you must use an RS-422/RS-232 adapter (provided as an option). The software can

be used to control up to 16 different units.

•

Redundant Interface connections are made via (J6) connector of each unit. Use the cable

provided to interconnect two (J6) ports to the waveguide switch. Follow instructions on the

labels on the cable.
