The DMM104 simultaneously drives four RCA S/PDIF outputs and one
TOSLINK™ output.
Propagation delay through either the DMM100 or the DMM104 is less than
100nS and jitter is under 5nSp-p.
All electrical inputs and outputs are transformer isolated, floating and DC blocked
to eliminate ground loop hum and jitter and to prevent transformer saturation due
to accidental superimposed DC line voltages. All inputs and outputs are properly
terminated for minimum signal reflection.
A green Signal Present indicator on the DMM100 and DMM104 illuminates when
a data carrier is output.
POWER
Both the DMM100 and the DMM104 operate from an external 24VDC power
module and each draws up to .1A. Loop-thru DC connectors allow multiple units
to operate from a single power module. Allow one power module for every three
one-rack spaces. Use power modules WA100-1, WA100-2 and loop-thru cables
20602-1. One WA100-1 115VAC Power Supply is included with each DMM100
or DMM104 ordered. For world-wide applications, specify WA100-2.
The DMM100-BAT and DMM104-BAT can operate from either four AA batteries
in cover-mounted holders, or an external 24VDC power module. Fresh alkaline
batteries will provide a minimum of 40 hours operation.
TOSLINK™ optical
drivers can be disabled with an internal jumper plug (JP1) to increase battery life
by 50%. Batteries are cut off by external power and can be used as an
automatically switched backup power source.
A front panel POWER switch and indicator are provided.
