1204A-MC Digital Signal Distribution With Remote Monitor and Control Interface

Building on the success of the 1204A Digital Distribution amplifier, the 1204A-MC is a flexible distribution platform suitable for various pulse formats enhanced with a full remote monitor and control interface. With the added monitor and control, a remote user can easily monitor status of each of the inputs/outputs of the unit on either RS232 or Ethernet with Telnet, web browser and SNMP interfaces. Optionally the unit can take two separate inputs into an input switch with either fully automatic or manual control.

For added flexibility, individual outputs can be enabled/disabled via remote control so that unused outputs are isolated from the alarm system. Input and output status is immediately evident from front panel indicators of each channel. Also auto/manual selection of the auto switched input is available from the front panel key pad. All outputs are provided on convenient BNC connectors. Outputs provide 5V TTL levels into a 50 ohm load.

 Input Frequencies DC to 30MHz
 Suitable for 1PPS, IRIG DCLS etc.
 12 Channel Output Distribution
 Low Skew and Propagation Delay
 Remote Monitoring of Input/Output Levels
 Remote Selection of Active Outputs
 Dual Input with Auto Switch Option
 Low Cost
 Convenient 1U, 19″ rack mount package
