Extended Protocol. This protocol selection includes error checking and transmission acknowledgment. It should be used in applications

where serial communication is a vital part of the marking operation. All communications are carried out in a parent/child relationship with

the host being the parent. Only the host has the ability to initiate communications. If the host does not receive a response within three seconds, it

should re-transmit its original message. If no response is received after three tries, it should declare the link to be down.

The following describes the Extended Protocol message format as sent from the host to the system PC.

SOH TYPE [##] STX [DATA TEXT] ETX BCC CR

SOH ASCII Start of Header character (001H). The controller

ignores all characters received prior to the SOH.

TYPE A single, printable ASCII character that defines the

meaning (type) and content of the message downloaded from the

host, where:

1 overwrites specified field of currently loaded pattern, using

the data format

nn<string> where nn is the field number.

P specifies pattern name to be loaded for printing

Q updates specified query buffer with data received from host,

using the data format

nn<string> where nn is the buffer

number.

V updates specified variable text field of currently loaded pattern,

using the data format

nn<string> where nn is the field

number.

O resets marker and places it online

G initiates a print cycle to mark the currently loaded pattern

I requests the marker return the status of standard output and

input signals in the hexadecimal format: O

; I

The first digit of the hexadecimal code reports the signal

states of output signals Spare-3 and Spare-2. The second

digit reports the states of output signals Spare-1, Spare-0,

Pause, Ready, and Done.

The third digit reports the signals states of input signals

Select-4 and Select-3. The fourth digit reports the state of

input signals Select-2, Select-1, Abort, and Go.

[##] Two optional ASCII decimal digits that specify the Station

ID number for use in multi-drop network applications. The ID

may range from 00-31. Note that “00” is reserved for applications

where only one controller is used. In such applications, this field

may be eliminated and “00” will be assumed.

STX ASCII Start of Text Character (002H).

[DATA TEXT] Optional character string that may be required for

certain message types (e.g., Type 1, P, Q, and V).

ETX ASCII end of text character (003H).

BCC Optional Block Check Code that is generated and sent to

improve link reliability by providing fault detection. The BCC is

calculated by taking an eight bit addition of the TYPE and DATA

TEXT characters and transmitting them as a three digit ASCII

decimal number in the range from 000 to 255. If the sum is greater

than 255, the most significant bit overflows and is discarded.

CR ASCII Carriage Return Character (00DH).
