Appendix B: Extender
Compatibility and Pinouts
The ServSwitch™ Brand CAT5 Extender Delay Line Module is compatible out the
box with the following models of Black Box CAT5 KVM extenders. If the model
you have is not listed, please contact Black Box Technical Support to find out
whether you can use the Delay Line Module with your extender and, if so, how you
can connect it.
ACU1001A, ACU1002A, ACU1004A, ACU1005A, ACU1006RA, ACU1006DRA,
ACU1006DSRA, ACU1006DVRA, ACU1006MRA, ACU1006MVRA,
ACU1006SRA, ACU1006VRA, ACU1008A, ACU1009A, ACU1012RA,
ACU1022A, ACU1028A, ACU1049A, ACU3001A, ACU3009A, ACU3022A,
ACUREM, ACUREMSW, ACUMREM, ACUSREM, ACUVREM, ACUWREM
The Delay Line Module can insert a delay on the three wire pairs carried on RJ-45
pins 1 through 6. The fourth pair (pins 7 and 8) is routed straight through. This
matches almost every CAT5 KVM extender on the market that uses three pairs for
R, G, and B video signals and the fourth pair for data. However, as there is no
industry-standard extender pinout, different manufacturers might use different
pairs for sending video and data. The Delay Line Module can be made to work
with extenders other than those listed above by using custom patch cables or just
simply noting that the color names printed on the Module for the switch banks
differ from the colors that are actually switched. For example, when you use the
Module with the ACU1600A ServSwitch™ Wizard Extender, which transmits red
on pins 3 and 6 and green on pins 4 and 5, moving the switches marked “Red”
actually affects the delay of the green color signal and vice versa.
To use the Delay Line Module with extender models other than those listed
above, compare the pinout of the extender’s RJ-45 twisted-pair connectors with the
pinout of the Module’s RJ-45 connectors, shown in Table B-1 on the next page.
Note any differences and, if necessary, adapt cables accordingly by swapping the
appropriate pairs.
