Contact Closure Control

Contact closure provides another method of input selection. To enable input selection by contact closure, you can connect a push-button contact closure device (such as Extron’s CCR 2BLB, CCR 4BLB, or CCR 204) to the SW USB’s Contact port.

Alternatively, you can manually short one of the pins to ground (the ground [_] pin is pin 3 for SW2 and pin 5 for SW4 models). Pin 1 selects input 1, pin 2 selects input 2, etc.

Controlling an Extron A/V switcher in Loop 0 mode

For applications in which the SW USB is connected to an Extron A/V switcher that can be controlled via RS-232, input selection on both switchers can be done by contact closure (as well as by the SW USB front panel buttons and the RS-232 interface). To select inputs on the A/V switcher via contact closure, the SW USB must be in Loop 0 mode (in other words, the SIS command ELOOP0}has been issued).

If the SW USB is in Loop 0 mode and an Extron A/V switcher is connected to the RS-232 Pass Thru port, an input selection command issued via contact closure selects the same input on both the SW USB and the connected switcher.

Using the SW USB with a contact closure device and an A/V switcher

To configure the SW USB for contact closure control of an A/V switcher,

1. If desired, connect a contact closure device to the SW USB’s Contact port.

2. Connect the SW USB’s RS-232 Pass Thru port to the A/V switcher’s RS-232 port.

3. Issue the SIS command E0LOOP}to the SW USB to enable Loop 0 mode.

Connecting Multiple SW USB Switchers in a System

The USB specification states that a maximum of five hubs can be connected in a series; therefore, no more than five SW USBs can be cascaded in a series.

CDo not exceed five cascaded hubs and a total of 127 peripheral devices in the entire system.

The diagram on the next page shows an example of SW USBs and peripheral output devices daisy-chained from a single host.
