f.  Install  the  four  2-56  cap  head  screws  into  the  four  mounting  holes  on  the  butterfly  package, 

securing the laser to the mount. 

g.  Swing the pin clamps back onto the ZIF socket, taking care that all of the laser diode pins are still 

aligned onto the correct contacts. 

h.  Press the latching mechanism forward onto the pin clamps until they snap into place, latching the 

pin clamps onto the pins and contacts. 

4.2.  Configuration Cards 

The LM14S2 is shipped with two configuration cards needed to program the unit for the proper pin-outs for the 
type of laser being installed in the mount. In most cases, the dual Type 1 / Type 2 Configuration Card can be used 
to route the DB9 input signals to the mounted laser diode. Refer to Section 4.2.1 for specifics on which side of the 
configuration card to use. 

For non-standard devices that do not use the pin-out conventions described on the next page, we have included a 
custom  configuration  card.  This  card  is  designed  to  allow  you  to  easily  configure  the  mount  to  any  pin 
configuration by soldering wires between the appropriate points on the card. For convenience, the outline of the 
butterfly package is shown on both sides of the card, in its proper top and bottom views. In addition, an extra set 
of holes is provided to allow multiple connections to one node. 

Ideally a solid 26 – 30 AWG insulated wire can be used for the various connections, but any suitable wire can be 
used. 

Refer to Tables Table

 1

 and Table

 2

 

for signal nomenclatures shown in bold type.
