Compact SW-RS POS interface and portion-control scale with RS-232, rear display and AC adapter. Choose the capacity shown in the existing variant; confirm exact POS protocol and cable before ordering.
CAS limits POS/ECR communication to lb, kg and oz; grams are a display mode.
No. The protocol, port, cable pinout and exact register/software revision must be confirmed.
The interface cable and host protocol require verification for the exact register or POS. Do not infer compatibility from connector shape.
Match the capacity to your heaviest item and container, then check resolution and space. Use the product options above to choose the exact configuration and see its current price and purchase controls.
For a connected installation, send the exact register/POS model, firmware version, scale model, host software, interface and cable part number. A matching connector does not establish protocol or pinout compatibility.

Send the exact register model, firmware version, scale model, protocol, interface and cable part number. SPS-300 and ER-900E support must be checked for that complete configuration; no universal pairing is promised.
Start with your maximum item weight and required resolution. Then confirm the display position, counter dimensions and any interface or label requirements. The table above lists the configurations currently offered for this model.
The exact register model, firmware, scale protocol, cable pinout and host software determine compatibility. Send those details for verification before ordering; a USB or serial port alone is insufficient.
Use the manufacturer document links in the specifications above. Match the document to your exact model and revision before changing settings.

Integrated payments mean the card terminal and the register talk to each other, so the sale is entered once and the totals agree at the end of the day.
No keying the total into a separate terminal, and no reconciling two sets of numbers because someone typed it twice.
The register, the peripherals and the payment side are set up together, so when something needs attention there is one number to ring.
We verify the register, the processing program and the integration path as one combination before recommending it, rather than assuming parts fit.
A processor change is not required to buy equipment. If you are already taking cards, send us a recent statement and we will tell you plainly whether a change is worth making.
The CAS SW-20RS is the 20 lb version of the compact SW-RS POS interface scale family. It is designed for retail counters that need legal-for-trade weighing and direct weight transfer to a compatible POS system or electronic cash register without taking up much counter space.
Platter size: 9.1 in W × 7.5 in D.
Compatibility note: interface cable is sold separately, and the required cable/protocol depends on the exact POS or cash register. Ask SAM4sDirect to verify the connection if you are unsure.
