Manual Reset
If any fault occurs during operation of the lamp (including actuation of the remote interlock),
the laser is immediately shut off, and light output ceases. When the fault condition is cleared,
the lamp will not automatically restart. The system must be manually reset by turning the
OPERATE switch to the OFF position. Then, assuming that the fault or interlock condition
no longer exists, the lamp can be restarted by turning the switch to the OPERATE position.
If a fault occurs while the lamp is not operating (switch in the OFF position), the switch must
be turned to OPERATE and then back to OFF to clear the fault. The lamp can then be
started normally by turning the switch to OPERATE.
Serial Interface
The RS-485 serial interface is provided for user adjustment of laser operating power, in order
to increase or decrease light output. The EQ-400 is shipped with the laser power set to a
factory default value of 100% of full scale power. Laser power can be increased or decreased in
increments of 0.5%, from 40% to 100% of full scale. The interface also allows monitoring of
system status.
Commands consist of a single ASCII character, case-sensitive. This can be transmitted to the
EQ-400 via a terminal emulation program, or the user's control system. Response from the
EQ-400 will be a string of ASCII characters, format depending on the command issued. Reply
strings are terminated by a CR - LF pair (hex 0D 0A).
The following describes the serial commands and their functions.
