NCI 6702 User Manual - Communication
Communication
The 67XX is capable of interfacing with an EIA Standard RS-232, full duplex,
asynchronous, smart device, or 4-bit parallel interface for output of weight data to
an ECR device. The 67XX 15 pin style is configured as a 4-Bit Parallel standard
from the factory. To configure the 67XX to the RS-232 interface operation, there
is a dip shunt jumper located at JMP 2 on the main PCB that needs to be positioned with
shortening pins placed away from the DE-15 connector or to the inside of the PCB. The
second uses a DE-9 connector and is only capable of communicating in the EIA Standard
RS-232 method.
This standard will be used by all products other than ECR scales.
