The first device in the line of XRGB upscan converters. It has four dip switches for changing configurations, and potentiometers to adjust colors and brightness.
|15 kHz / 31 kHz
||Adjust output scan rate
|NTSC / PCB
||75 ohm / 220 ohm setting
|FM Towns /Normal
||Special setting for FM towns computer
|Normal / Narrow
||Control aspect ratio (*)
(*) note that only V2.2 PCB has DIP switch for Normal / Narrow, the V1.1 PCB only has three DIP switches.
- RGB in 15-pin D-sub (for older Japanese monitors, can be connected to VGA via special cable)
- RCA stereo out
Note! 15-pin D-sub adapter to 9-pin D-sub (standard VGA connector) use Sanwa AD-D15NE (can also be used on the input).
| Ver 1.1 PCB
|| Ver 2.2 PCB
Note! the bigger 100uF are the ones that leak first (V1.1 C97,54), V2.2 seems less susceptible for leaking caps.
There are two known variations shipped in the box, the 500mA version seemed to been with the earlier ones and 300mA with the later revisions.
JOD-41-051 (91-53131) 500mA
JOD-2053 (91-57573) 300mA
