• STX: start of text code value equals 02H. • Byte Count This indicates the number of data bytes (maximum 255 bytes) which have been inserted between this byte and the Checksum byte. Values 00H, 01H, 02H are illegal values. • Destination address: One byte address value which defines who the message is for. Value 01H should be specified. • Source address: One byte address value which defines where the message came from. This is who to reply to with the message. Value from 41H to 7FH should be specified. • Command Block This designates a particular command. Refer to “Command Description” (on page 7) for the details. • Checksum This value is set so that the bottom eight bits of the sum of all bytes from the byte count to the checksum inclusive are zero.

Command Block Format / Communication Protocol

Communication Protocol The remote controller should take the initiative in communication between the remote controller and the monitors. The monitor will carry out one of the following actions when receiving the message. • When the received message is an undefined message, a communication error occurs or the automatic adjustment of APA or AUTO CHROMA/PHASE is working, a NAK (05H) is issued. • When the received command is a question, the specific replay and data are issued. • When the received command is anything else, an ACK is issued. The next message can be received as soon as a NAK is issued from the monitor to the remote controller. Notes

• If there are not enough or too many data bytes of data values then a NAK is issued and no values are specified. • Bits which are not specified here are undefined bits and their values are always ignored.

Connections Pin assignment for the RS-232C connector is as follows. 5

This protocol provides the following features when individual monitors are controlled. • Switch functions can be changed. • The ability to remotely make settings and adjustments normally made with the monitor’s menu.
