ZuluSCSI Compact Homebrew jumper placement

[varmfskii]

Which ones should be installed (there is space for five jumpers and the kit comes with three) ? What do they do? What is JP201 for? Is terminated with term_en open or closed?

@varmfskii generally, you will want to solder down the headers for:

• J311 - TERM_EN (closed=SCSI termination enabled, open=disabled) and leave a jumper on it, unless you intend to use the ZuluSCSI device in the middle of chain of SCSI devices.
• J310 - Initiator mode. This jumper header must remain open if you want to use your ZuluSCSI as a standard SCSI storage device, and closed if you want to use the ZuluSCSI in initiator mode
• J304 - Activity LED - this allows you to attach an external activity LED to the ZuluIDE, if desired.

The jumper at J313 does nothing unless you also have a piezo buzzer installed, which is not supplied with the kit, because we've found most people do not want or need such functionality. It exists solely for you to be able to wire an in-line switch (or jumper it permanently on) in the event that you want to be able to enable and disable the sound it generates via any sort of normally-closed switch.
