DELTX-UI, DELFX-UI AND DELF3-UI
SPECIFICATIONS
The DLE2X-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 Unshielded Twisted
Pair (UTP) cabling.
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.
