7    Installation of DSP Upgrade Board

The installation of an additional DSP circuit board will permit recording on four additional lines.  With two DSP boards installed up to sixteen lines can be recorded simultaneously. 

Upgrading Total Recall to Higher Channel Capacities

The 4, 8, and 12 channel versions of Total Recall can all be upgraded to a higher channel capacity by the addition of a 4-channel (Part Number TR-U4) or 8-channel (Part Number TR-U8) DSP card. Total Recall can accommodate 2 DSP cards only so the upgrade may necessitate the prior removal of an existing DSP card(s). Possible permutations:

TR-U8 (8-channel DSP Card)

7.1  Requirements

         Copy of this procedure.

         Additional DSP circuit board.

         A clear and clean flat surface at least 750mm wide by 370mm deep.

         Anti-static workstation (ideal).

         Screwdriver suitable for M3 pan head screws.

         (8) off M3 x 15 mm hex spacer with one end having an M3 stud.

         (4) off M3 x 6 pan head screws.

7.2  Procedure

7.2.1  Disconnection of the power and telephone lines to the Total Recall unit 

Switch off the Total Recall unit at the back of the enclosure.

Switch off the 110/240VAC supply at the power point and then remove the plug. 

Withdraw the IEC connector from the back of the Total Recall enclosure.

Mark the telephone lines so that they can be replaced in the same locations.  Remove the telephone line RJ jack plugs from the back of the Total Recall Unit.

7.2.2  Opening the Total Recall Case 

Invert the unit onto a clean and clear flat surface. Take general precautions to prevent damage to the LCD display from objects underneath.

Undo the seven M3 x 12 pan head screws located in D recesses.

Holding both halves of the case together return the case to the normal position.

Slowly lift upwards the top half of the Total Recall case until the internal studs inside the top case are clear of the lower case.  The right hand side can now be rotated 180 degrees to the left so that the inverted top half lies next to the bottom half.  Do not attempt to move the top half any further until the interconnecting cables have been disconnected.

7.2.3  Fitting the additional DSP circuit board

The installed DSP board is located at the back of the lower case and is secured to the lower case by four M3 hexogen standoffs at each corner of the DSP circuit board. 

         With all anti-static precautions in place remove the additional DSP board from the anti-static bag and take off the protective packaging and inspect the lines of pins of the PC104 connector to ensure that they are not bent.

         Visually align the underside pins of the additional DSP circuit board with the black PC104 socket J3 of the installed DSP circuit board.  Taking care to ensure correct alignment of the pins, gently press down at either end of the J3 socket on the additional DSP board until the new DSP sits on to the four standoffs.

         Secure the additional DSP circuit board with four M3 x 6 mm pan head screws.

         On the top DSP circuit board fit a shorting link ON JP1 located top center.  No link is to be fitted on JP1on the lower DSP circuit board.

         Remove the detachable blanking plate from the back of the top half of the case.

No additional connections are required.  The new DSP circuit board will be configured automatically by the system when power is restored.

7.2.4  Reassembly of the Total Recall case and reconnection of telephone lines and mains power

The reassembly of the Total Recall case is the reverse of the previous procedure.  A brief outline is listed below.

         Rotate and lift the top half of the case back onto the lower half of the case.

         Holding both case halves together, invert the unit.

         Secure the case halves with the M3 screws.

         Return the unit to the normal position.

         Reconnect the telephone lines.

         Connect the IEC mains power lead.

         Connect the three-pin mains plug to the power point.

         The Total Recall unit is now ready for power to be switched on.
