Introduction
The SR5 coin acceptor can operate entirely in serial mode with all conventional
control and status functions implemented in the serial protocol.
The serial protocol is cctalk, now a standard for the money transaction industry.
Full details of the protocol can be found in the following document, available from the
customer services department of Money Controls…
‘cctalk Serial Communication Protocol - Generic Specification - Issue 4.0’
The generic specification explains the history and design philosophy of the protocol,
the message structure and a complete list of commands covering different types of
money transaction peripherals.
Listed below are the command headers available to SR5 and any product-specific
features which you need to know about.
Implementation on SR5
The protocol conforms to cctalk b96.p0.v12.a5.d0.c5.m0.x8.e0.i0.r4
In other words…
•9600 baud
•open-collector
•+12V nominal supply
•+5V data pull-up
•supply sink
•connector type 5
•slave device
•8-bit addition checksum
•no encryption
•cctalk minor release 0
•cctalk major release 4
To operate in serial mode, ensure that pin 9 of the 10-way serial connector is tied
low and the mech powers up in this state. Although some serial commands appear to
operate correctly in parallel mode, the product will not function entirely as described
below.
Device Address
All SR5’s leave the factory with address 2.
The address is stored in EEPROM and can be subsequently changed with serial
commands. Unless you have an application requiring more than one coin acceptor on
the serial bus, it is strongly recommended you leave the address alone. The default

addresses for hoppers and bill validators have been made different and will not clash
with the coin acceptor.
If the address has been changed to an unknown value then you will either have to
search all through the entire address space ( 2 to 255 ) with the ‘Simple poll’
command until an ACK is returned or send the ‘Address poll’ command with the
broadcast address.
Electrical Connections
Only 3 wires are required for the interface between a SR5 and the host machine.
(1) /DATA
(7) +12V
(8) 0V
(9) /SERIAL MODE
Pin 9 should be tied to 0V on the connector ( pins 2 or 4 can be used ) to operate the
SR5 in serial mode.
The bi-directional data line operates at 9600 baud, 1 start bit, 1 stop bit and no parity
bits. There is no option to select a different baud rate.
The data pin on SR5 is pulled up to +5V via a 10K resistor and should be driven with
an open-collector transistor.
Pin 5 is a hardware /RESET line but no connection needs to be made. A software reset
command is provided for this purpose.
Inhibits and Overrides
SR5 can accept 16 different coins including a special token selected from a bank of
12 if in ‘token mode’.
There are 16 inhibit bits used in the ‘Modify inhibit status’ command allowing any
combination of coins to be accepted or rejected.
There is support for 8-way routing with a 7-way override.
There are 7 override bits used in the ‘Modify sorter override status’ command
allowing complex routing patterns to be achieved.
Each coin can have 4 paths programmed into EEPROM. If the first path has an active
override, then the coin will be routed down the second path. This continues until all
the assigned paths have overrides when the coin will be sent down the default path.
The default path can be changed with the ‘Modify default sorter path’ command.

SR5 has a new command called ‘Modify inhibit and override registers’ which allows
current and next coin values to be sent. This allows accurate coin-by-coin acceptance
and routing, overcoming the inherent latency in serial operation.
At power-up or reset, all coins are inhibited and all sorter overrides are removed.
Coins cannot be accepted until a non-zero inhibit mask is sent to the mech.
Credit polling
Coin credits are obtained by polling the coin acceptor at regular intervals using the
‘Read buffered credit or error codes’ command. Up to 5 credits or errors are stacked
in the return buffer.
The return data is 11 bytes in length.
[ event counter ]
[ result 1A ] [ result 1B ]
[ result 2A ] [ result 2B ]
[ result 3A ] [ result 3B ]
[ result 4A ] [ result 4B ]
[ result 5A ] [ result 5B ]
A & B are formatted as [ credit code ] [ sorter path ] or [ 0 ] [ error code ] depending
on the logged event. See Table 2 in the generic specification for a list of error codes.
Note that the event counter wraps from 255 to 1, not 0.
A suitable polling interval is anywhere between 100ms and 900ms. If other cctalk
peripherals are on the bus then these may have to be polled as well.
SR5 has a credit poll watchdog feature whereby if the mech is not polled for 1s or
longer then the device auto-inhibits and does not accept any more coins. When polling
resumes, the auto-inhibit is lifted. This feature prevents coin swallowing in the event
the host machine serial link goes down. Note that insertion of coins during a credit
poll auto-inhibit increments the insertion and reject counters but does not generate an
event in the event buffer ( cctalk header 229 ). Also, the individual and master inhibit
settings are not altered.
Sorter Operation
To ensure that the cctalk serial commands ‘Modify sorter paths’ and ‘Request sorter
paths’ operate as expected, the coin acceptor must be in EEPROM routing mode.
Please state this is the option you require when ordering product from the factory.
SR5 can operate without a sorter, or in 4-way and 8-way routing configurations.
This table shows how the different modes relate to each other.

Serial Teach
Coins and tokens can be taught using the ‘Teach mode control’ and ‘Request teach
status’ commands. This method involves the insertion of a small sample of coins (
typically 8 ) but the process can be controlled entirely over serial.
If a token is taught then after the teach process send a ‘Reset device’ command to
force the new token to be used ( alternatively, cycle the power ). The rotary switch
should always be on position ‘C’ for the teach token.

Calibration
SR5 implements ‘calibration’ which is the Money Control’s system for remote coin
programming. Using this method, a new coin set can be programmed into SR5
without inserting any of the coins themselves.
Remote coin programming uses the ‘Upload window data’ and ‘Download calibration
info’ commands.
Further details of calibration are not given in this document. If you are interested in
remote coin programming then contact Money Controls for the latest policy and
support equipment.
Command List
The following table shows all the cctalk commands available for customer use on
SR5. More details can be found in the generic specification.
Any [ data bytes ] are shown in decimal.
DCE = Dual Coin Entry rundown. This is a ‘Y’ chute with optos in the coin and token
entry slots.
MDCES = Multi-Drop Command Extension Set. These commands are only used
when peripheral addresses are unknown.
Header numbers are shown in descending order.
*** SR5 has 66 serial commands ***
