the input's data field, and can be used to specify transmit pauses, embedded header inputs, and the

data file name.

Field Requirements:

•

Prefix is not required

• 0 to 32 maximum characters allowed

• alpha, numeric, and all other ASCII characters are accepted

NOTE: Any ASCII character may be input by a 3 character sequence of "/nn" (/nn is the HEX

value of the character). Since a / is the start of any HEX value, you must type "//" to

output a slash. Function keys may be defined as /F0 through /F9. Function key F10 is

defined as /F0. Refer to Appendix K and L for Special Character values.

Prefix Delay

The Prefix Delay defines the duration of the time delay that is inserted between the transmission

of each character of the Prefix. It is used to slow down the data output rate so the M3000 does

not cause a data overrun on the host computer during transmission, especially when transmitting

data by keyboard wedge. The time delay is incremented in tenths of a second. Most systems can

use a Prefix Delay of zero (0).

Field Requirements:

•

Prefix Delay is required

• 1 to 2 characters allowed

• numeric data accepted (0-9)

Suffix

The Suffix is a string of characters output after the input field data has been sent during data

transmission. The Suffix is used to specify delimiters between fields and also to define any

special keys or data that must follow the input data, and can be used to specify transmit pauses,

embedded header inputs, and the data file name. The default suffix "/0D", outputs a Carriage

Return (ASCII 13).

Field Requirements:

•

Suffix is not required

• 0 to 32 characters allowed

• alpha, numeric, and all other ASCII characters are accepted

NOTE: Any ASCII character may be input by a 3 character sequence of "/nn" (/nn is the HEX

value of the character). Since a / is the start of any HEX value, you must type "//" to

output a slash. Function keys may be defined as /F0 through /F9. Function key F10 is

defined as /F0. Refer to Appendix K and L for Special Character values.

Suffix Delay

The Suffix Delay defines the duration of the time delay that is inserted between the transmission

data by keyboard wedge. The time delay is incremented in tenths of a second. Most systems can

• 1 to 2 characters allowed

• numeric data accepted (0-9)
