5045, selecting MODEM CONNECTION resets the TRACER 5045 to the password entry screen.
Table 5 contains the wiring diagram needed for connecting the TRACER 5045 RS-232 interface to a
modem using the null modem adapter.
Test (1/4” bantam)
The TEST interface displays the QPSK constellation when connected to an Oscilloscope in X/Y mode.
This test point is for technicians experienced in microwave technology and should be used primarily when
dealing with ADTRAN Technical Support.
10/100BaseT/TX Connections (RJ-48C)
The physical Ethernet interfaces are provided by four RJ-48C jacks that deliver 10/100BaseT/TX
interfaces for LAN connectivity. Each port has a green
LINK LED to indicate a valid link and an amber
ACT LED that blinks with data activity on the interface.
Hangup-on-DTR-drop may need to be explicitly enabled on some modems.
