4.1.6 Lamp House I/O
The black 21-pin mixed D-sub cable is used to connect the lamp head to the power supply controller. This cable should
be connected before AC power is applied to the power supply controller.
4.1.7 RS-485 Interface
Connector J2 is a standard 9-pin male d-sub. Mating connector is a standard 9-pin female d-sub (for example, AMP
part no. 205203-3 with contacts 1-66504-0). See
10.3 RS-485 Interface Pin Assignment
for pin connections.
Port settings are 9600 bps, 8 data bits, 1 stop bit, no parity, no handshaking.
Installation of the
EQ-77X
consists of connecting electrical, cooling fluid, and purge gas supplies, as well as connecting
the lamp head module to the user’s equipment. Read
first before making any connections.
4.2 Installation Procedure
The lamp head should be mounted with the output window on the side and the lamp mounting surface
oriented horizontally. The lamp head has been factory aligned in this position. Mounting the lamp in a different

1. Place the power supply controller on a stable surface. The power supply controller must be placed within 2
meters of the lamp head due to the length of the interconnecting cable. See
for
dimensional details.
2. Connect the lamp head unit optical output to the user equipment (after removing the window cover). The
beam should always be either directly coupled to a fiber optic cable, or enclosed in an appropriate beam pipe,
tube, or enclosed space and purged with nitrogen. Operating the source without any output target or beam
transport is not recommended, and may lead to unsafe operating conditions. Consult Energetiq
for applications
information and suggested configurations.
