WARRANTY 54
MPS2 based machines are designed and built to take advantage of the system capabilities. As such, servicing and repairs
should Only be carried out by trained personnel. Modifications to assemblies should not be undertaken except as and when
detailed by J.P.M. (Automatic Machines) Limited.

MPS2 INSTALLATION PROCEDURE
Installation Procedure
1. Ensure that all plugs and sockets are engaged, also that all earth connections are secure.
2. Connect to mains supply and switch on at the transformer assembly.
3. During power up, a tone will sound and the power on reset LED on the main board will illuminate for
approximately 3 seconds then extinguish.
4. For correct operation, the following segments of diagnostic LED 5 will illuminate.
The power supply LED's 1 -3 (+5v, +12v, -12v) should also be illuminated.
5. After the initial reel spin you may proceed with the self test routine as detailed in the personality package.
The function of each individual segment is as follows:
TOP UART2 TX ON = Transmit Data.
TOP LEFT I/O Enable ON = Enable.
TOP RIGHT UART2 RX ON = Receive Data.
CENTRE NM1 ON = Interrupt State.
BOTTOM LEFT Reel Drive Enable OFF = Enable.
BOTTOM RIGHT MUX Timeout OFF = Timeout.
BOTTOM Peripheral Communication ON = Transit Data.
DECIMAL POINT Not Used
Mains Input
The mains transformer has the facility to be operated from 200v, 220v or 240v AC input. This is achieved via a
plug fitted to the exterior of the chassis. The plug is polarised and can in no way be inserted incorrectly. For
connector details see label on power supply chassis.

INTRODUCTION
Since the introduction of MPS1 , J.P.M. have decided to keep in line with technical advances and following their
continuous policy of improvement to introduce MPS2.
The MPS2 PCB is electronicaily compatible with the MPS1 PCB. The PCB is mounted in a moulded plastic
enclosure of the same size as the MPS1 PCB, thus making both units retrofittable. Cut-outs are provided for the
memory PCB and the bus interface connector .
As with the MPS2 main board, the new Linear PSU is completely compatible with the MPS1 power supply as
well as being especially designed for MPS2 machines.
The new power supply is designed to aid service engineers in the repair of J.P.M. machines.
This service manual should enable the field service engineer to ensure that the MPS2 machine is installed and
operating correctly, and also to assist him locate and correct any faults that may occur. It will also assist the more
technically minded workshop engineer via the circuit diagrams and the detailed explanation of the various
electronic circuits.

SYSTEM CAPABILITIES
Sound Generation
Complex Sound Generation utilising the TI SN 76489. The power output is 2W into 8 Ohms. There is on board
volume control, capable of being by-passed by the alarm signal.
Serial Communication
This is achieved via the RS 232 interface.
Data Storage
This is achieved by 2K bytes (expanding to 8K x 8) Cmos RAM. Battery back up is provided by an on board re-
chargeable NI-CAD battery with a 5 year life.
On Board Switches
The following are provided:
1 off - Hexidecimal rotary switch (0 to F).
1 off - 8 way SPST DIL switch.
MK 3 Memory Board
The memory board consists of three 28 pin sockets and an IC for address decoding. The IC (74LS139N)
provides additional address to that already present on the MPS1 and MPS2 main boards. The three 28 pin
sockets can take either 8K x 8 (2764), 16K x 8 (27125) or 32K x 8 (27256) EPROM's, giving the memory board
a capacity of between 24K (3 x 2764's), 48K (3 x 27128's) or 48K (1 x 27256 and 1 x 27128).
The decoding for these types of EPROM's is selectable by links 1 to 5 on the Memory card:
For 3 x 2764, links 4 and 5 inserted.
For 2 x 2764 and 1 x 27128, links 4 and 5 inserted.
For 3 x 27128, link 3 inserted.
For 1 x 27256, links 1 and 2 inserted.
Power Supply
The supplies for MPS2 are of the linear variety and include.
a) +5v at 1.5 A.
b) +12v DC at 1.8A.
c) -12v DC at 0.2A.
Unregulated supplies are:
1) 50v DC at 5A Lamps Supply (VMUX).
2) 24v DC at 1 A Reel Supply.
3) 50v AC at 2.5A AC payout solenoids.
4) 110v AC at 1.3A Hopper Supply.
5) 48v AC peak at 100mA - Low Mains Supply Sensor .
6) 128v AC at 1 A -Video Monitor Supply.
For further information on specification of power supply see pages 5 & 6.
