6 Commands
1.1 Changing the I2C
Slave Address
Immediately changes the I2C write address. Only even values are permitted as the next odd address will become
the read address. Default is 80.
Address
1.2 Changing the
Baud Rate
Immediately changes the baud rate. Not available in I2C. Baud rate can be temporarily forced to 19200 by a
manual override.
Speed
1.3 Transmission
Protocol Select
Selects the protocol used for data transmission from the display. Data transmission to the display is not affected.
Must be set to the protocol in use to receive data correctly.
Protocol
1.4 Turn Software
Flow Control On
Enables simple flow control. The display will return a single, Xoff, byte to the host when the display buffer is
almost full and a different, Xon, byte when the buffer is almost empty. Full value should provide enough room for
the largest data packet to be received without buffer overflow. No data should be sent to the display between full
and empty responses to permit processing. Buffer size is 128 bytes. Not available in I
Full
Empty
1.5 Turn Software
Flow Control Off
Disables flow control. Bytes sent to the display may be permitted to overflow the buffer resulting in data loss.
6.1 Communications
1 byte, valid settings shown below
1 byte, even value
1 byte, number of bytes remaining before buffer is completely full, 0 < Full < Empty < 128
1 byte, number of bytes remaining before buffer can be considered empty enough to accept more data
1 byte, 1 for Serial (RS232/RS422/TTL/USB) or 0 for I2C
