Connection to the interface is made us-
ing the 8-pin DIN receptacle on the rear
of the
I 10. The pinout and pin connec-
tions are shown on the security plate
label.

The I 10 will not output data un-
less pin 3 is held in an ON state
(+3 to +15 VDC). Interfaces not
utilizing the CTS handshake may

Data output can be initiated in one of
three ways: 1) by pressing PRINT;
2) using the Auto Print feature; 3) send-

All communication is accomplished us-
ing standard ASCII format. Only the char-
acters shown in the following table are
acknowledged by the
I 10. Any other
commands, control characters or spaces
are ignored.
Commands sent to the I 10 must be
terminated with a carriage return (CR) or
carriage return-line feed (CRLF). For
example, a tare command should ap-
pear as shown in the adjacent diagram.
Data output by the
I 10 is always termi-
nated with a carriage return-line feed
(CRLF).
