Description
This section describes the procedures for the repair/replacement of the press-fit connector
pins used on the backplane of the 1665 DMX shelf. Trouble clearing procedures may lead
you to inspect the backplane for damaged connectors.
Circuit packs are plugged into METRAL™ signal pin connectors which have been press-
fit into the backplane. A plastic shroud is included with the connectors to protect the pins.
The signal pin press-fit terminals in these connectors my be replaced individually if they
have been damaged beyond simple repair methods.
D-subminiature connectors
Interface cabling to and from the 1665 DMX shelves is connected through D-
Subminiature connectors which have been press-fit into the backplane. Should these
connectors be damaged beyond simple repair methods, contact your next level of support
for the replacement procedure.
RJ45 jacks
Interface cabling to and from the 1665 DMX shelves is connected through RJ45
connectors (jacks) which have been press-fit into the backplane. Should these jacks be
damaged beyond simple repair methods, contact your next level of support for the
replacement procedure.
Shelves and backplanes
The 1665 DMX has its connectors and terminal identifiers stenciled on the back surface
for identification of location or position. The stenciling can only be seen when the back
cover is removed.
Pins are identified by a column and row position on the backplane. D-Subminiature
connectors are identified by their designation and J-number. All the METRAL™ pins used
on the 1665 DMX shelves have the same tail length of 4.30 mm (0.169 in.).
