6504A. This switch is optional for the 6504B, and is located on the rear panel when it is furnished. The Datum 6504 IRIG-B Distribution module accepts a single IRIG-B timing signal and provides ten buffered IRIG-B timing signal outputs.
PREPARATION FOR SHIPMENT To turn off the Datum 6504 prior to shipment, remove the AC power from the plug on the rear panel. Package the instrument in its original packing if possible. If the original packing materials are not available, pack in a reinforced cardboard carton using foam to take up any space inside the carton.

FIGURE 2-1. AC INPUT FILTER/FUSES/VOLTAGE SELECTOR The Datum 6504 may be powered from 120 or 240 VAC. To change the AC input between 120 and 240 VAC, refer to Figure 2-1. Open the cover on the AC input connector by applying a screwdriver to the cover slot.
DAISY-CHAINING MORE THAN ONE MODULE If more than ten outputs are required, up to ten Datum 6504 modules can be driven by a common input signal to produce up to 100 outputs. Figure 2-4 illustrates this connection.
(or last) chassis in the daisy chain is set to 50Ω. ALARM CONNECTIONS The Datum 6504 provides for an alarm to signal the failure of any signal output. One set of form-C relay contacts is provided on the 9-pin D connector labeled ALARMS. For normal operation, pins 1 to 2 are open and pins 1 to 3 are closed.

Chapter Three OPERATION The Datum 6504 IRIG-B Distribution controls and indicators are described in this chapter. Two chassis configurations are described, the 6504A and the 6504B. The only difference between the two chassis configurations is that the ALARM OVERRIDE switch is optional for the 6504B, and when it is furnished with the 6504B it is located on the rear panel.
HI Z/50Ω – This slide switch on the rear panel selects either the HI Z input impedance (unterminat- ed) or the 50Ω input impedance. A 6504 installation of two or more (ten maximum) units will require the switch to be set to the HI Z position on the module connected to the source of the signal, and on all subsequent modules except the last module, which is switched to the 50Ω...
