nSTROBE

Input

 

To scan data, make sure that the pulse width of the

 

 

 

 

 

 

 

 

strobe pulse is set to more than 1 µs.

 

 

 

 

 

 

 

 

 

The regular status is “High”, however, if it is “Low”, the

 

 

 

 

 

 

 

 

data will be scanned in the first transition.

DATA 1 to DATA 8

Input

 

DATA1=LSB DATA8=MSB

 

 

 

 

 

 

 

 

 

Positive logic code

 

 

 

 

 

 

 

 

 

 

 

ASCII or JIS7 as well as 8.

 

 

 

 

 

 

 

 

 

10

 

nACK

Output

 

A low level pulse signal will be output when data

 

 

 

 

 

 

 

 

scanning is complete to inform the host.

 

 

 

 

 

 

 

 

 

11

 

BUSY

Output

 

“High” will be maintained when the Reception buffer

 

 

 

 

 

 

 

has reached full or when an error occurs in the printer,

 

 

 

 

 

 

 

and “Low” will be output when the printer is ready to

 

 

 

 

 

 

 

receive.

 

 

 

 

 

 

12

 

 

PE

Output

 

The level will become “High” when labels have run out

 

 

 

 

 

 

 

 

and none have been set.

 

 

 

 

 

 

 

 

 

 

 

13

 

SELECT

Output

 

The signal will be in “High” level when reception is

 

 

 

 

 

 

 

 

possible, otherwise it will be “Low” level.

 

 

 

 

 

 

 

 

 

32

 

nFAULT

Output

 

The signal will be in “High” level when reception is

 

 

 

 

 

 

 

 

possible, otherwise it will be “Low” level.
