To select a channel:

1.Press the ▲ or ▼ key to scroll to the channel number required. The switch mechanism advances to the channel when the key is released.

In SB-C models (SB1CXXXXX+2XXXXXXXX), the channel number displayed is the current channel number connected to the common fiber C (the switch has one common fiber).

In the SB-D models (SB2DXXXXX+2XXXXXXXX), the channel number displayed is the current channel pair (the switch has two common fibers).

In the SB-E models (SB2EXXXXX+2XXXXXXXX), the channel number displayed is the channel connected to the common fiber B. The channel connected to the common fiber A is B - 1 (the switch has two common fibers).

In SB-F models (SB2FXXXXX+2XXXXXXXX), the channel number displayed is the channel connected to the common fiber B. A blocked connection with B shows as an even-numbered channel and the connected channels with B show as odd-numbered. The path connected to common fiber A is B - 1.

In all configurations, channel 0 is an open circuit, that is, the switch is in an unconnected state.

Setting the GPIB Address

Set the SB switch to GPIB mode to display and edit the GPIB address:

1.Press the GPIB ADDR key. The current GPIB address is displayed.

2.To change the address, press the ▲ or ▼ key to scroll to the required address.

3.Press the GPIB ADDR key to store the new address. Or, to exit GPIB mode without changing the address, press the DRIVER 1 key.

Setting the Interface Command Set for SC and SX Switches

The SB switch can be set to emulate the interface command sets of earlier models of JDS Uniphase SC Series and SX Series switches.

To set the interface command set:

1.Press and hold the GPIB ADDR key while the SB switch powers up. The active interface command set is displayed.

2.Press the ▲ key to scroll to the required command set, for example, SB, SC, or SX.

3.Press the GPIB ADDR key to save the setting.

Controlling the Drivers

The SB switch has four drivers (drivers 1, 2, 3, and 4) for driving the external switch modules and four drivers (drivers 5, 6, 7, and 8) for driving internal switch modules in custom
