Connecting the Optima APOS Series with CAS and Brecknell Scales

This article will provide general setup information and pin outs for the supported CAS PD-II series scales, and Brecknell 6700U series scales. All but the APOS-01 systems that has the 6-pin RJ-12 RS232 serial connector will require an adapter cable in order to connect to the following supported brands and models below. 

IMPORTANT: Any scales used in a commercial or industrial trade environment must be calibrated and certified by a weights and measurements agency mandated by state/provincial or federal law. Please check your local laws regarding weights and measures certification.

USA: NIST - Office of Weights and Measures

Canada (EN): ISED - Measurement Canada

Canada (FR): ISDE - Mesures Canada

Setup Process and Requirements

The setup process in this guide can be done while in GoPOS (Home Menu > Menu > Settings > Hardware > Add New Hardware > Scale) or PCProg (Hardware Module > Add New Hardware [+] > Hardware Type > Scale). You will need to define at least one department with the Scalable option on, and Print Weight/Volume Info Line on to ensure communication between the scale and the APOS system and the proper information printed out on the receipt. You may also need to define the base weight unit in the General Settings of GoPOS (Home Screen > Menu > Settings > Options > Setting 18) or PCProg (Settings Module > Setting 18).

Serial Port: 6-pin RJ-12 RS232

When setting up the serial configuration for the 6-pin RJ-12 RS232 serial port, you must define the serial port number, which is dependant on the APOS model. In either PCProg or GoPOS, enter the following Serial Port value that corresponds with your APOS model in the Hardware Settings when defining scale communication:

Serial Port: 4-pin RJ-11 RS232

On some APOS models, the scale can also be connected with the 4-pin RJ-11 RS232 serial port. The Serial Port number are identified in the following APOS models:

IMPORTANT: Please note that the primary port for connecting any serial devices to any serial ports on any of the APOS systems will be on the 6-pin RJ-12 RS232 port. Therefore, the pin outs will be based on the RJ-12 connector. Please contact Optima Support if you are connecting a scale using the secondary 4-pin RJ-11 RS232 port on the select models above to confirm pin outs for the secondary RS232 port.

CAS PD-II

The Optima GoPOS software supports serial models that have either the 9-pin DB9 RS232 connector or 25-pin DB25 RS232 connector.

IMPORTANT: Please consult the CAS PD-II User's Manual for more information on how to access and manage the settings, or contact Optima Support for assistance.
