RS-232 Control

Transmission Speed	19200 BAUD

Transmission Data	Data Length: 8, Stop Bit: 1, Parity Bit: None

No standard hardware or software pacing is used such as DTR/RTS or XON/XOFF. Commands should be paced using the ACK, NAK, UNK, or ERR responses from the display.

Standard RS-232 levels, +/- 12V, are used. Some laptop PC’s use ground and +5V and are not always successful in communicating with the display.

The display’s RS-232 port is always active except during the boot process which is the first 10 seconds after power is applied to the display electronics.

In single address mode (not when global commands are being used) the host machine should wait for an ACK, NAK, UNK or ERR response from the display before sending the next command to avoid overrunning the input buffer. When global commands are sent, the displays will not return a response, so a delay of ½ second should be maintained between commands to avoid possible errors.

The protocol for communication to the display consists of a 7 byte command line as described below.

STX(1 byte) IDT(2 byte) CMD(3 byte) ETX(1 byte)

Where;

ASCII STX - Start of transmission character, = 02h
