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).
