Manual
INSTALLATION
LOCATION
The MCDA is readily installed into a 2 RU, 19” rack. The MCDA is only to be installed in an inside
location where it is protected from inclement weather. Operate the MCDA in temperature range of +5 to
+40°C (105°F), with relative humidity ranging from 5 to 85%.
POWER
Connector for socket fused IEC 320/C13. Power cord is supplied. The MCDA has a rear panel On Off
power switch.
POWER INPUT SPECIFICATIONS:
Voltage .......................................................................................85 ~ 264Vac
Frequency .....................................................................................47 to 63Hz
This equipment is connected to earth through the center conductor of the AC mains cable. Proper
grounding protects user/operators from electric shock, and it must be maintained whenever the unit is
connected to AC.
WIRING
XLR inputs for external clock sources require special controlled impedance, 110 ohm, low loss, foil
shielded, twisted pair cables. Standard audio cable is not recommended. Belden and most other cable
manufacturers offer special digital audio cabling for this application. BNC connectors use 75-ohm coax
(RG59). Select a cable for losses less than 20dB at 12MHz (for data rates up to 96 k samples) at the
maximum distance you require. Keep cable length as short as possible, especially when working with
Super Word clock rates.
