JLCooper PPS-2Plus - Manual (Page 2)

Remove the Old EPROM
Remove the old EPROM by very gentle and gradual prying with a small, flat bladed screwdriver. Carefully insert
the screwdriver between the socket and the EPROM. You will get into very serious trouble if you accidentally pry
up the socket.
Install the new EPROM
Remove the new EPROM form its protective foam. Make sure that all of the pins are straight. Be certain that notch
is oriented correctly before insertion. Do not pay any attention to the orientation of the EPROM's label! A label
may be put on backwards, but the notch is always correct. Gently insert the EPROM into the socket, and when you
have verified that all pins are going where they're supposed to, carefully but firmly press down.
Inspection and Warning
Inspect that the EPROM looks like it has been inserted correctly. If the EPROM is inserted backwards it will be
destroyed, and the sync box may be damaged! If any pins are "bent under" or "hanging out" it will be destroyed, and
the sync box may be damaged!
Replace the Cover
Put the top cover back on the chassis and secure with four screws.
To Use the PPS-2 Plus as a MTC to SMPTE Converter
All the original functions are still present and operated normally.
To convert MTC to SMPTE, set the switches for MTC, and READ.
Make sure that the software you are using is set up to transmit MTC.
Send MTC into the PPS-2's MIDI input.
Once the PPS-2 receives the MTC message, which switches it sync box internally to the MTC-to-SMPTE mode.
As soon as the PPS-2 Plus receives MTC, it will start generating SMPTE. The SMPTE being generated will have the
same time and frame rate as the MTC.
Connect the SMPTE output to any synchronizer that reads SMPTE.
To Use the PPS-2 Plus as a SMPTE to MTC Converter again.
To resume converting SMPTE-to-MTC, switch the PPS-2 OFF, and then back to READ.
Remember that MTC coming into the MIDI Input will immediately switch the PPS-2 Plus into an MTC to SMPTE
converter. So, if you want the PPS-2 to stay in its original SMPTE to MTC conversion mode, be sure that you do
no accidentally send MTC into the MIDI In. That could happen if you have a MIDI Patch Bay accidentally set to
loop the MIDI Out of the PPS-2 back to itself. Likewise, if your sequencing or recording software sends out MTC,
be sure that you do not accidentally send it back into the PPS-2 Plus.
