6.5.2.13 Command 228 [hexE4], Modify master inhibit status
This command is used to inhibit acceptance of all coins and has same effect as
command modify inhibit status with sent with two bytes of zeros. Host sends only one
byte of data. If first bit (
LSb
) is set to “0” coin selector is inhibited. Bits 1 to 7 has no
influence to coin selector. Message format is:
Host sends:
[Dir] [01] [01] [E4] [Mask.] [Chk]
Coin s. respond:
[01] [00] [Dir] [00] [Chk]
ACK
Initially coin selectors are programmed with acceptance enabled.
Change is stored in RAM location .
On customer demand it is possible to set inhibition as default .
Example of message string to inhibit the acceptance for coin selector(
address 2
) is:
Host sends:
[02] [01] [01] [E4] [00] [18]
Coin s. respond:
[01] [00] [02] [00] [FD]
ACK
After that coin selector acceptance will be inhibited till reset or next instruction that will
change master inhibit status.

Only first (
LSb
) bit is used. If bit 0 is “1” acceptance is enabled, and if bit 0 is “0” coin
selector is inhibited and acceptance is disabled.
Other bits has no meaning and always read as “0”. Message format is:
Host sends:
[Dir] [00] [00] [E3] [Chk]
Coin s. respond:
[01] [01] [Dir] [00] [Mask.] [Chk]
Example of message string for coin selector(
address 2
) after power-up is:
Host sends:

[02] [00] [01] [E3] [1A]
Coin s. respond:
[01] [01] [02] [00] [00] [FC]
Coin selector inhibited
