Remove the pullout members from both drawer slides by extending the inner most section to its maximum and then depressing the retaining clip while sliding the pieces apart. Attach the two pullout members to each side of the LDM-4616 with the eight 8-32 x 3/16” pan head Phillips screws. See Figure 2.1. -

Page 21: Connecting The Ldm-4616 Mount To A Laser Diode Controller
ILX Lightwave when standard ILX Lightwave cables are used. The 9-pin D-sub connectors have standard ILX Lightwave pin-outs. If you are using any other laser driver, use extreme caution when connecting the cables from the mount to the driver. Check the pin-outs of the laser driver and temperature controller for compatibility with this mount before connecting the mount. -
Page 22: Figure 3.1 Back Panel Tec Connector
The mount chassis is grounded through pin 3 of the Channel 1 laser connector. This pin must be grounded to ground the mount chassis. Standard ILX Lightwave cables and laser current sources ground pin 3 automatically. The pin-out configurations of the 9-pin D-sub connectors on the LDM-4616 mount are shown below in Figures 3.1 and 3.2. -
Page 23: Configuring The Pin Headers To Match Your Laser Pin-Out
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. -

The next step is to configure the pins for each socket using the wires supplied with the LDM-4616 shipping kit. On the bottom of the module are three pin headers for each of the four sockets. Two of the three headers are labeled with laser package pin numbers and the third header is labeled with electrical connections from the back panel inputs. -

These pins are usually a common ground and one or two other functions, and there are typcially more than one per package. - Page 26 If the previous information does not adequestly explain how to configure the mount for your laser, or if you are not sure if your electrical configuration is correct, do not operate the laser.

Page 27: Front Panel Fiber Optic Mating Adapters
Front Panel Fiber Optic Mating Adapters Front Panel Fiber Optic Mating Adapters The front panel of the LDM-4616 mount has 16 holes with adapter plates installed that will secure mating adapters with a standard square flange configuration (“FC flange” type). Many different “FC flange” type mating adapters are available to accommodate several different types of fiber optic connectors. -
Page 28: Passing Fiber Through The Front Panel
Figure 3.6 Attaching Mating Adapters Inside Passing Fiber Through the Front Panel Fiber can be passed directly through the front panel holes of the LDM-4616. We recommend putting the rubber grommets from the shipping kit in the holes to protect your fiber. If your fiber has an FC, ST, or SC connector on it, you can pass the connector through the front panel holes with the grommets removed. -
Page 29: Mounting Your Laser Diodes
The cover improves thermal stability and helps provide shielding from radiated noise and transients in your laboratory. The LDM-4616 mount is equipped with a grounding connection on the right side of the front panel which is electrically connected to the chassis of the mount. We strongly recommend that you electrically ground yourself with a wrist strap. -
Page 30: Inserting Your Laser
Some laser packages have leads that reside high above the bottom of the package (i.e. 7.6 mm is a common “high” dimension). If the leads on your laser sit much above the socket contacts, call ILX Lightwave to get a set of spacers that raise the socket contacts. -

Visible and / or invisible laser radiation is dangerous and may cause serious eye damage. Avoid direct exposure to the beam. Be sure all laser fibers, connectors and mating adapters (like on the front panel of the mount) are connected or capped before turning on any lasers. 05_11 LDM-4616 ... - Page 32 O P E R A T I O N C H A P T E R Front Panel Fiber Optic Mating Adapters LDM-4616...

Page 33: Socket Numbering And Mount Modules
Numbering Sockets When Installing New Modules There are several different types of mount modules that can be installed in the LDM-4616 chassis. The chassis can be purchased separately (ILX P/N LDM- 4600). When installing modules into a chassis, each socket must be numbered correctly to coincide with the correct back panel connector. - Page 34 1-4, the middle left module has channels 5-8, the middle right module has channels 9-12, and the right most module has channels 13-16. Within each module, the least significant number is at the back with increasing numbers moving toward the front of the chassis. See Figure 4.1. LDM-4616...

Page 35: Maintenance And Safety
Safety Laser diodes used with the LDM-4616 Laser Diode Mount may emit infrared radiation which is invisible to the human eye. Viewing of emissions from the fiber may cause eye damage. Extreme care must be taken to prevent the beam from being viewed either directly or through external optics or mirrors. - Page 36 M A I N T E N A N C E A N D S A F E T Y C H A P T E R Safety LDM-4616...
