3.1.2 D-Subminiature Cable Connections

Type 'D' Connection Type
Chassis Receptacles:
(TOP) Female
(BOTTOM) Male
Type 'D' Cable With Jack Screws
(Female Shown)
D-Subminiature connectors are also called Type 'D' or 'D-Sub' connectors. The connector pair features
multiple rows of pins (male side) coupled to mating sockets (female side). The cable plug and chassis
receptacle each feature a D-shaped profile that interlock to ensure proper pin orientation and connector
seating.
Either chassis receptacle gender features two jack nuts for secure assembly of the cable plug to the
chassis receptacle.
Whether its gender is male or female, the cable plug features two jack screws for secure connection to
the jack nuts provided on the mating chassis receptacle. The jack screws may be hand tightened or
tightened with a standard flat-blade screwdriver.
Connection Instructions: Orient the plug to the receptacle in the proper position. Press firmly into place.
Use the jack screws to secure the plug to the receptacle jack nuts. Do not over-tighten.
About connector pinout tables: Figure 3-2 identifies the Pin 1 location for either gender connector.
Unless noted otherwise, the connector pinout tables provided in this manual arrange/order information
(i.e., the Pin # column/row) based on this orientation.
3.1.3 RJ-45, RJ-48 Cable Connections
The plug for an RJ-45 or RJ-48 cable features a flexible tab. The RJ-45 or RJ-
48 jack features a mating slot. This design configuration assures proper
installation and pin orientation.
Connection Instructions: Press down the tab on the cable plug, and then insert the plug into the RJ-4x
jack. The connection is complete when the tab 'clicks' into position inside the jack.
