TP500 Module Connections
Power Connector
A Molex-style connector is used to provide -48 volts DC (labeled Power). When the
unit is successfully powered, the PWR LED near the left side of this panel will
illuminate green. If the power connection is reversed, the unit will not be damaged, it
simply will not power-up. Startup power will be < 17 watts. Steady-state power
(nominal 25° C) <9.5 watts. The TP500 Client module uses –48 VDC power and is
not equipped with a power switch. Power to the unit is controlled by TimeAnalyzer’s
DC power supply.
RJ48C Connectors
The stack of 2 RJ48C connections labeled SPAN1 and SPAN2 (can use standard
Ethernet cable) provides two separately driven output signals, configurable as either
E1 or T1. These are differential outputs (tip and ring) conforming to signal levels
defined in G.703.
Warning:
To avoid serious personal injury or death, exercise caution
when working near high voltage lines and follow local building
electrical codes for grounding the TimeAnalyzer
Note:
The RJ48C physical connector is the same as RJ45 (an 8-pin
modular connector). RJ45 is used for Ethernet whereas the term
RJ48C is used for T1 lines. The pinouts for RJ45 and RJ48C are
different. RJ45 (Ethernet) uses pins 1, 2, 3 and 6 whereas RJ48C
uses pins 4 and 5.
