A&D SW-15KM, SW-6KS, SW-30KM, SW-60KL, SW-60KM, SW-150KM, SW-15KS, SW-150KL OP-04 Specifications, Ascii

‰The installation procedure is the same as for OP-03. Refer to “13.2.1. Installing OP-03”.

‰Set the function settings “bp5”, “btpr”, “prt”, “5if”, “adr” and “aCk” as necessary.

‰Before using OP-04, the function setting “5if” must be set to specify whether RS- 422 or RS-485 is used.

To connect more than one scale to a computer, set a different address to each scale using the function setting “adr”.
