Serial communication interfaces
RS232C:
①Unidirectional communication. Only the
indicator can transfer the data to computer, the
computer can not control the indicator.
②Baud rate: 1200/2400/4800/9600 optional.
③Data for RS232 communication is in ASCII
code as below:
The 1st bit is starting bit, the 10th bit is stopping
bit, and the middle 8 bits are data bits. Even
check.
④Transmission distance<10m
Cable specifications:
2-core shielded cable
Material：Copper

When the cable is longer than 3m, it‟s strongly
advised to add a magnetic loop (optional
component) on the RS232 interface of the
indicator to enhance the anti-interference ability

1.2 INTRODUCTION OF INDICATOR
XK3190-A12(E) weighing indicator is non-automatic weighing indicator applied to platform scale. It can
be connected to electric platform scale, electric floor scale, and can be connected 1-4 350 ohm load cells. It
is mainly applied to enterprise with factory, wholesale market, bus station, port, mine, warehouse etc, all
kinds of weighing occasions.
The indicator is composed of anti flaming ABS plastic housing, PCB, LED/LCD indicator, keypad, power
transformer and AC power plug, fuse, load cell socket, RS232 interface, 6V/4AH rechargeable battery. A/D
conversion adopts － MCU with excellent stability and anti interference
ability.
A12(LCD) has three types of backlight user mode: still closed, still open and automatic. Under
automatic mode, backlight will be off automatically after the indicating weight is stable for few seconds.
