SW VGAxi / MACxi Switchers

Installation and Operation

The SW VGAxi / MACxi are 350 MHz bandwidth switchers are housed in rack mountable, 1U high, half width metal enclosures with internal, universal 100 - 240 VAC 50/60 Hz power supplies. They have built-in standard contact closure remote control capability with Tally through the 25 pin Contact Remote connector (see Contact Remote pin assignments - Figure 4-A). Optional remote controls available for both switcher types are the KP-10 wired remote with 25 foot cable, the IR-10 Infrared remote control with an operating range of approximately 30 feet and the RS-232 2,4,6,8 Controller. VGAxi switchers are available with 2, 4 or 6 inputs while the SW MACxi is only available with 2 inputs. If more than 2 MAC inputs are required, the SW4 VGAxi or SW6 VGAxi may be used with VGA/MAC adapters (see connection diagram in Figure 3-A and Part Numbers on Page 5).

Auto-switching

Auto-switching is a feature of the SW VGAxi and SW MACxi switchers that can be enabled/disabled using a switch on the rear panel (see item E in Figure 2-A). With the AUTO/MANUAL switch in the AUTO position, the front panel AUTO SWITCH ACTIVE LED is ON, the input selection buttons are disabled, and the switcher automatically selects the highest number input that has sync pulses available.
