SOF Text

The start of file text can be any text or special characters that you want transmitted before each

data file is transmitted. This string of text or special characters can be used to send commands to

your computer so it will be ready for the data record transmission.

Field Requirements:

• SOF Text is not required

• 0 to 250 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. PC 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.

SOF Delay

The start of file text transmit delay defines the amount of time delay that is inserted between each

character of the SOF Text during file transmission. This is used to slow down the data output rate

so that the M3000 does not generate a data overrun on the host computer during transmission,

especially when transmitting data by keyboard wedge. The time delay is in tenths of a second (0.0

- 9.9 seconds). Most systems do not need an SOF Delay.

Field Requirements:

• SOF Delay is required

• 1 to 2 characters allowed

• numeric data accepted (0-99)

EOF Text

The end of file text can be any text or special characters that you want transmitted after each data

file is transmitted. This string of text or special characters can be used to send commands to your

computer to exit your receiving program after data record transmission.

Field Requirements:

• EOF Text is not required

• 1 to 250 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. PC 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.

EOF Delay

The end of file text transmit delay defines the amount of time delay that is inserted between each

character of the EOF Text during file transmission. This is used to slow down the data output rate

so the M3000 does not generate a data overrun on the host computer during transmission,

especially when transmitting data by keyboard wedge. The time delay is in tenths of a second (0.0

- 9.9 seconds). Most systems do not need an EOF Delay.

Field Requirements:

• EOF Delay is required

• 1 to 2 characters allowed

• numeric data accepted (0-99)
