MCA527

Command name

CMD_WRITE_EXTENSION_RS232_TX_ASCII

Compatibility

New MCA527 command.

Execution right

Necessary

Description

The command is intended for transferring strings via the RS232 interface. Each call writes up to 6
characters to the end of the RS232 transfer buffer. A zero character terminates the string and starts
the transfer. The transfer buffer is 300 bytes long. If it is full, the transfer is started automatically.
Before starting a new string transfer, it is recommendable to check the RS232 transfer buffer byte
count (see CMD_QUERY_STATE527_EX, byte offset 80). If the transfer buffer is not empty, it can be
cleared with CMD_CLEAR_EXTENSION_RS232_TX. It is also possible to clear the transfer buffer
preventively without checking the byte count.

Command name

CMD_WRITE_EXTENSION_RS232_TX_BINARY

Compatibility

New MCA527 command.

Execution right

Necessary

Description

The command is intended for transferring bytes via the RS232 interface. Each call writes up to 4
bytes to the end of the RS232 transfer buffer.
flags:

bits 2...0:

000

write 0 bytes

001

write 1 byte

010

write 2 bytes

011

write 3 bytes

100

write 4 bytes

bit 7:

1 = start transfer

The transfer buffer is 300 bytes long. If it overruns, it will be cleared and the command will be return
“invalid parameter”.
Before starting to fill the transfer buffer with new data, it is recommendable to check the RS232
transfer buffer byte count (see CMD_QUERY_STATE527_EX, byte offset 80). If the transfer buffer is
not empty, it can be cleared with CMD_CLEAR_EXTENSION_RS232_TX. It is also possible to clear
the transfer buffer preventively without checking the byte count.

Command name

CMD_START_EXTENSION_PULSER

Compatibility

New MCA527 command.

Execution right

Necessary

Description

The command starts the selected pulser. The command will only be executed successfully if the
corresponding parts have been correctly configured (see CMD_SET_EXTENSION_PORT).
part:

1 = part B (pulser2)
3 = part D (pulser1)
7 = part B (pulser2) and part D (pulser1)
