Shipping Contents
The contents include the following items:
• Total Reach DDS‐DP
• Total Access 1500 Total Reach DDS‐DP Job Aid (P/N 61180105L1‐22)
Instructions for Installing the Module
The TR DDS‐DP plugs directly into a Total Access 1500 shelf. No special wiring is required.
The 2‐wire loop uses the T/R (Tip and Ring) pair, pins 15 and 35, of the Total Access 1500
backplane.
Remote Unit Span Power
The TR DDS‐DP span powers the remote unit by providing ‐130 VDC measured from Tip to
Ring. Voltage measured from Tip to GND should be ‐130 VDC or less depending on voltmeter
impedance. Voltage from Ring to GND should indicate approximately 0 V.
Front Panel LEDs
The TR DDS‐DP provides front panel LEDs to display status information. The TR DDS‐DP
LEDs and status descriptions are shown in Table 4.
