4.1.1THE VIDEO-HANDLING JUMPERS JP2 AND JP10

Jumpers JP2 and JP10 in the Local Module control how the Extender handles video signals, depending on whether the computer outputs VGA signals to the Extender’s HD15 connectors or legacy Sun signals to the Extender’s 13W3 connectors, as well as what type of signal input the monitor accepts. Refer to Figure 4-2 on the next page:

•If the computer attached to the Local Module outputs VGA video, and the monitor attached to the Remote Module accepts VGA input, leave jumpers JP2 and JP10 in their default settings: JP2 installed, JP10 empty.

•If the computer outputs VGA and the monitor accepts Sun input, leave jumper JP10 in its default empty setting, but remove jumper JP2. In this setting, automatic gain control (AGC) isn’t possible, so you’ll have to turn it off at both the Local and Remote Modules (see Sections 4.1.2 and 4.2.1) and set the gain manually (see Section 6.2).

•If the computer outputs Sun video, regardless of what the monitor accepts, leave jumper JP2 in its default installed setting, but also install a jumper on JP10. You might also need to set jumper JP9 in the Remote Module (see Section 4.2.2).
