PARSEC Supergun v2.1 Instructions
Thank you for purchasing the Parsec supergun.  It has been designed to offer high compatibility, safe for vintage arcade boards, and have exvellent picture and sound quality.  
POWER
The Parsec only functions as a pass through connector for powering your arcade game PCB.  It is important to use a good quality power supply with ATX compatible 20 or 24 pin connector.  Arcade power supplies can also be used with a correctly wired ATX harness.  Most JAMMA arcade games use 3 - 10 amps at +5v.
To connect an arcade power supply to the Parsec, purchase a 24 pin ATX extension cable, cut off the male pin end, strip the wires and connect them to the arcade power supply's screw terminals.  Refer to the ATX pinout below.  The Parsec's on-board power switch does not function when using an arcade power supply.
It is strongly recommended to use a multimeter and take voltage measurements of the incoming +5v and +12v before and after connecting your JAMMA arcade game PCB.  There are labeled pins on the Parsec (near the ATX connector) for easy voltage measurement.  Measurement range listed below:
+5v measurement  =  5.0v - 5.15v
+12v measurement = 12.0v - 12.4v
CAUTION:  If voltages are higher than listed, damage could occur to a connected arcade game PCB.  If the +5v input is higher than 5.5v, the Parsec could be damaged.  Immediately power down the system and locate the cause if the voltages are higher or lower than above specification.
The on-board -5v regulator is powered from the +12v supply and turned on/off by the large slide switch near the ATX connector.  This switch should be turned "ON" when no -5v is present at the ATX connector and the arcade game requires -5v.  Turning this switch to the "OFF" position connects the ATX -5v pin to the JAMMA power pin.  On board LEDs indicate voltage present:  Red = +5v,  Green = -5v,  Blue = +12v

VIDEO
Parsec has 3 built-in video output options with 75 ohm drivers:  RGB, s-video, and composite video.  All 3 video outputs may be used at the same time.
CSYNC output is SCART level;  jumper "J1" can be bridged if TTL level composite sync is required.  Do not bridge "J1" pins unless you're sure the monitor supports TTL level sync.
3 potentiometers are used for adjustment of red, green, and blue video signals.  Turning these clockwise increases the brightness.  It is best to start with the potentiometers in the fully counter clockwise position and increase brightness if necessary.  It is normal for RGB video to be brighter than composite & s-video.
Parsec is compatible with 8 pin mini-DIN cables utilizing the XRGB mini Framemeister pinout.  A correctly wired RGB SCART cable will have directly connected red, green, blue, and sync wires (no inline components.)

Optional A/V Expansion HAT
The optional video HAT PCB has a supplementary VGA style connector for RGB video output, space to mount a Viletim component video add-on PCB for 240p YPbPr video output, and 1/8" stereo auxiliary audio in/out jack.
The 1/8" "AUX AUDIO" jack functions as an input to the 8p mini-DIN connector only when a plug is inserted into the "AUDIO LINE OUT" connector on the main Parsec PCB.  Any 1/8" headphone plug can be inserted into the "AUDIO LINE OUT" connector to disable the JAMMA audio connection.
The "SYNC" switch selects between 2 different sync output options to the VGA connector:  Composite sync (C) or separate TTL level horizontal and vertical sync (HV.)
The Viletim component video add-on PCB connects to the HAT with 5 soldered header pins, and also requires 2 jumper wires from the Pb and Pr outputs to the red and blue RCA connectors.  This add-on PCB is available from the etim online shop:  etim.net.au/shop
The 240p YPbPr component video output is not compatible with many TVs made after 2012 or so.  If there is no video output on your TV, this may be the case.
Component video and s-video cannot be used at the same time.  Parsec can drive only one RGB output.
AUDIO
An on-board switch selects JAMMA mono or stereo sound (stereo sound is only supported on compatible Neo Geo boards.)  Audio output is provided through either a 1/8" stereo line out jack or the 8 pin A/V out connector.  The 8p A/V out audio is disabled when a cord is plugged into the "AUDIO LINE OUT"  jack.
Note: The "AUDIO LINE OUT" connector is not designed for headphones.
Leave the "STEREO/MONO" switch in "MONO" position unless using a compatible Neo Geo MVS or other PCB supporting JAMMA stereo.
Parsec has an isolated audio ground feature to eliminate interference from the main system ground.  The "AUDIO GND" switch is located between the composite video connector and audio output jack.  This switch must be in the "GND" position to use the 8p A/V connector for sound.  To use isolated grounding, plug an audio cable into the 1/8" "AUDIO LINE OUT" connector and move the "AUDIO GND" switch to the "ISO" position.
CONTROLS / KICK HARNESS
Parsec has two Neo Geo compatible controller ports for players 1 & 2.  In order to use Parsec with 6 button games, a correctly wired kick harness and compatible controller are required.  Refer to the controller wiring diagram on page 4.
A 6 pin 2.5mm pitch JST connector is used for the kick harness connection.  Standardized pinout used by many popular superguns.
The six DIP switches connect / disconnect button inputs 4 - 6 from the JAMMA connector.  These switches can be left off for most games.  For Neo Geo MVS, turn on button 4 switches.  Atomiswave requires button 5 switches on.  Unless playing one of the newer arcade game PCBs supporting 6 button JAMMA, the switches for button 6 should always be left off.
JAMMA ARCADE GAME CONNECTION
CAUTION:  Check all connections and switch positions before powering on the PARSEC.
The actual JAMMA arcade game PCB should be connected last.  If the height of the two JAMMA connectors is off, use a spacer (such as a dvd case) to raise the Parsec up to the same height as the arcade game PCB.  When plugging in your JAMMA arcade PCB, use care to make sure the pins are properly aligned and fully inserted straight into the connector.  When unplugging the arcade PCB, use your thumbs on both sides of the connector and apply equal pressure to remove the Parsec straight out.
COMPATIBILITY
Parsec is designed for maximum compatibility with the majority of JAMMA arcade games and RGB displays / converters.  However, there may be some games and RGB displays that are not compatible.
