Connect TTL signal source to the U-type module via the Molex connector
Connect pin 7 (ENABLE) to a TTL signal source. In order to operate the unit,
pin 7 (ENABLE) must be connected and must be driven high (>3.6V).
Pin 7 (ENABLE) can be used to turn the laser off in case of emergencies by
driving low (GND).
3.
Connect the U-type module to the host system
If using USB, connect the USB
cable provided from the U-type module mini USB
connector to the host system.
If communicating to the device via I2C or RS232, pins 3 (SCL/TX) and 4 (SDA/TX),
need to be connected to the controller.
Please note, for boards with RS232 enabled, the USB and I2C busses will be
disabled.
The customer should specify which I2c address they want before we ship to
them if they plan to integrate more than 1 laser in the same system using I2c as
the data interface.
If you have an I2c configured laser and try to use RS-232 on the TX/RX lines, it
may damage the logic board.
Some customers might attempt to connect directly from USB to these TX/RX
lines, this may also damage the logic board.

Ensure the U-type module is recognized by the host system by opening the
Windows® Device Manager. If using an alternate Operating System, please contact
IPS for additional details on verifying device recognition.
Locate “Ports (COM & LPT)” in the Device Manager. Ensure “USB Serial Device (COMX) is
present.
If “Ports (COM & LPT)” does not appear, it’s possible it is hidden (select the “View”
drop down and “Show hidden devices”). If “Ports (COM & LPT) still does not
appear, please visit the Microsoft® answers page to view steps to enable legacy
hardware.
The U-type module uses a serial interface, with COM port settings of 115200
baud and 8N1 configuration.
