APPENDIX B
DELTX-UI, DELFX-UI AND DELF3-UI
SPECIFICATIONS
The DLEHF-MA supports three Fast Ethernet Interface Modules:
•
DELTX-UI
•
DELFX-UI
•
DELF3-UI
This appendix provides the specifications for these modules.
B.1
DELTX-UI
The DELTX-UI uses an RJ45 connector supporting Category 5
Unshielded Twisted Pair (UTP) cabling with an impedance between 85
and 111 ohms.
The slide switch on the DELTX-UI determines the crossover status of the
cable pairs. If the switch is on the
X
side, the pairs are internally crossed
over. If the switch is on the
=
side, the pairs are not internally crossed over.
Figure B-1 shows the pinouts for the DELTX-UI in both positions.
