Protocol
One of two protocols is selected by DIP-SW.
The module processes all received data; the display address setting is ignored.
Direct mode is applicable for all interfaces.
The module only processes data in packets with an address that matches the display's address set
by DIP-SW + MSW.
Using this mode, a maximum of 255 displays can be controlled individually.
Data in packets addressed to FFh is processed by all connected displays.
Packet mode is applicable for Parallel and RS-232 serial interface.
Packet response can be sent, depending on MSW setting.
If packet address and display address matches, and packet is correctly received, ACK reply is sent
from display.
For packets addressed to FFh, only the display with address 00h sends a response.
If a BCC or other error occurs, no response is sent.
The packet response is sent with priority, which may corrupt any data remaining in the display's
transmit buffer, so the host should wait until all data has been received before sending the next
packet.
Commands
This section describes the operation of each command.
Within these explanations, Character (x-dot) and Line (y-dot) refer to the number of dots determined
by the “Font size select” and “Font magnification” settings, etc.
For commands that produce response data from the display, this data is placed in the send buffer,
then transmitted. When DSR=MARK (BUSY), data transmission is halted, and during any time when
there is no space in the send buffer, command processing is halted. Caution is needed when using
these commands via the parallel interface.
