The Model 9744 uses two front panel rotary knobs for its simultaneous switching. The left-hand rotary knob switches the entire RJ11/12 32-channel group from A or B positions and the other rotary knob switches simultaneously. The right-hand rotary knob switches the A and B positions of the single DB9 channel. Two center pins of the RJ11/12 interface and all 9 pins of the DB9 interface are switched via a break-before-make rotary switch. The switch ports are transparent to all data and they are manually operated so that no power is required and the switch has the highest level of security.
The Model 9744 Switcher is delivered in an attractive all metal black box enclosure which provides EMI/RFI shielding. The switchbox is configured as a 5U rackmount unit, full rack size with dimensions of 19.0 Wx8.75 H x13.0 D and a weight of approximately 16.0 lbs. The switcher is designed to permit quick and easy switching to backup devices. To ensure a fully reliable application, all purchases of the switch include a lifetime warranty against manufacturing defects.
