This is an example showing a normal communication sequence in the
MiniMech
TM
end of the communication cable. The example shows
communication with handshake control. The handshake circuits is only
activated when the dispenser has something to send.
If handshake with the host
is not required, pins 4 & 5 in the 25 pin DSUB
connector must be connected together according to chapter 6.6.2. This will
have the effect that CTS = RTS and communication timing are stated
only by
the RxD and TxD lines below.
Description Name Min (ms) Max (ms)
Delay before dispenser issues RTS for sending ACK t0 - 10
Delay between CTS activated and ACK sending t1 - 10
Time between ACK is sent and RTS deactivated t2 25 75
Delay between CTS activated and reply sending t3 - 10
Time between reply is sent and RTS deactivated t4 5 15
Max time waiting for ACK from host t5 - 500
Delay before dispenser issues RTS for sending EOT t6 - 10
Delay between CTS activated and EOT sending t7 - 10
Time between EOT is sent and RTS deactivated t8 5 15
Time to execute command t9 25 120000
