Electro Standards LaboratoriesA/B Switch with Remote ControlModel M4520
Description
Model 4520 AB network switch supports switching all 15 signals of the DB15 connector interface.
Local switching via front panel pushbutton.
(2) Status LEDs, A/B, on the front panel indicate the switch position and power status.
Remote control via contact closure control across pins 1 & 2 of the DB9 REMOTE port connector.
Power supplied to unit over pins 7 & 8 of the DB9 connector.
Copper contacts permit signals to pass through the switch. Unit is transparent to data and speed.
Switch maintains position and signal pathway even if power to the unit is lost.
Ground stud on rear panel to provide single chassis connection for shielding .
Four threaded steel inserts, 6/32 thread size, on bottom side of unit to allow fixed mounting of the unit to a surface.
