Connecting the LDM-4616 Mount to a Laser Diode Controller
Pin 3 of the 9-pin D-sub connector for the Channel 1 laser current must be connected to
ground for the mount chassis to be grounded. Standard ILX Lightwave cables and
instruments will have the laser connector pin 3 connected to ground.

Configuring the Pin Headers to Match Your Laser Pin-Out

This secion does not apply to the LDM-4616DFB version which has a fixed pin
configuration. The DFB version has "DFB" printed on the circuit board which can
be seen through the finger holes in the front of the laser sockets. If you have the
DFB version, verify your lasers have the same pin configurations as listed in
Chapter 1.
The LDM-4616 mount is equipped with electrical pin configuration headers
(terminal blocks) which allow the mount to be used with various laser diode pin-
outs. These headers must be configured before mounting your lasers. Wires are
included with the LDM-4616 shipping kit for configuring the headers.
First, remove the mount tray cover by lifting up on the figer tabs, then pull the
cover toward you. It will slip off the hinge pins. There are four laser mounting
modules in the tray. Each module consists of four butterfly sockets on a pedistal
which is connected to a printed circuit board (PCB). There is a black plastic cover
with two finger holes in the PCB. Numbers on the black plastic coincide with the
channel numbers on the back of the mount. There are three fiber management
clips in the black plastic.
