DC-530 Operation Manual

7.4

Setpoint Connector

Your DC-530 has a setpoint output that can be attached to output relays for setpoint control of external

equipment when setpoint conditions are satisfied. The device receiving the signal is connected to the DC-530’s

Setpoint Connector (see Figure 7-1).
To set up the DC-530 to output when the setpoint conditions are satisfied, program the customer specifications as

detailed in Section 6.4.

7.5

Bar Code Scanner

A laser scanner allows for instantaneous and accurate input of basic data for an item. The DC-530 has bar code

scanning capabilities by plugging the optional QS-6000 Bar Code Scanner (Part No. 65619) into the RS232C-1

port on the scale (see Figure 7-1). In the Counting Mode the scanner can be used to enter the Unit Weight, the

Tare Weight, and the Item Code. In the Programming Mode you can scan in the Part Code, Unit Weight, Tare

Weight, and Setpoints.
To setup the necessary specifications for bar code scanning, set the DC-530’s specifications as follows:

•

SPEC 04 - Bar Code Scanner to 0010

•

SPEC 06 - RS232C Output to 1001

•

SPEC 07 - RS232C1 Baud Rate to 0100

•

SPEC 08 - RS232C2 Parity/Bit/Stop Bit/Data Length to 0000

•

SPEC 55 - Scan Quantity Type must be set for either Item Quantity (the default) or Accumulation

Quantity.
