Command :03 04 01 A5 14 00 64 01 DA
Response: 01 00 03 00 FC
The 4 bytes
(14 00 64 01)
transmitted with the command have the following meaning:
<current limit, motor stop delay, payout timeout, single coin mode>
In this example the hopper is set in single coin mode.
(0 = multi coin mode (default), 1 = single coin mode)
In single coin mode, only 1 coin at a time can be dispensed.
This mode can only be set to multi coin mode again by resetting the hopper.
A hopper reset will set all variable settings to their default values.

Table 5: Hopper Variable Settings
[Motor current limit]
If the current through the motor is above the threshold level (3.3 A) during 160 ms, the motor will
reverse for 250 ms to clear the blocking.
[Motor stop delay]
This is the time delay after the last coin is paid out before stopping. This should ensure a clean coin
exit.
[Payout Timeout]
This is the total time each coin is allowed to leave the hopper, including some reverse time in jam
situations. If the hopper is empty, the motor will stop after 10 sec (default value).
[Peak current measured]
This is the maximum motor current measured, and gives you an idea about the peak current your
power supply must handle. Start and stop currents in the Flow hopper are software controlled and do
not have steep slopes (about 0.5 Amp/ms). If the peak current exceeds the Absolute Maximum
Current Level (6.3 Amp) after a delay of 2 seconds then the hopper will return a NAK response on a
Start Payout command, because the bit B0 in the Hopper Status Reg1 will be set.
A Reset command will clear the error.
[Supply voltage]
This is the measured supply voltage the hopper runs on.
[Connector address]
The address of the hopper after a power up or reset is equal to this a 3
