BLUE BOX 449 RS-449 BREAKOUT BOX Data and Clock LEDs can monitor signals up to 3 Mbps Test voltages allow signals to be forced On or Off Two 37-pin panel-mounted D-type connectors allow connection to RS-449 interface Two 120 ohm resistors provided for terminating signals 7 hours of continuous use provided by two 9V batteries Power On/Off switch conserves battery life Size: 5.3" x 4.2" x 1.9" (13.5 x 10.7 x 4.8 cm) The Blue Box 449 conforms 100% to all RS-449 specifications. This small, battery-powered, breakout box allows the user to isolate, access, and monitor all 37 conductors of the RS-449 interface between DTE and DCE at data rates up to 3 Mbps. All signals can be interrupted and cross-patched using IDS' unique stacking jumpers. Red and green LED pairs monitor the status of 13 primary, key interface signals. Analogous to traffic lights, the red LEDs indicate the OFF or "Stop"condition and the green LEDs indicate the ON or "Go" condition. One spare monitor circuit is also provided. Two pulse trap circuits allow the user to capture transients and crosstalk pulses as short as 20 nsec in duration, fast enough to capture transients and pulses on both T1 and E1 networks.
