Note
Many newer Laptop PCs are not equipped with serial ports and only have USB ports. These
PCs will require a USB RS-232 adaptor that can be purchased commercially.
The RS-232 Interface Cable
The physical connection between the flow meter and your PC is accomplished using a serial
interface cable, part number: 1015CPC-N. The schematic below shows the configuration of
the cable. The wire ends for the flow meter termination are tinned for easy insertion into TB1
on the flow meter. Each wire is labeled to identify the correct terminal pin on TB1. In addition,
both connectors have their CTS pin shorted to the RTS pin (pins 4 - 5 on 25-pin connector
and pins 7 - 8 on 9-pin connector) and this eliminates the need for hardware "handshaking."

Figure A-7 1015CPC-N Serial Interface Cable
Due to the different SITRANS F 1010 flow meter configurations, there are 3 types of RS-232
communication cables employed. You can determine which cable is required for your model
flow meter from the table below. Be sure you have the appropriate cable available for use.
For those who would prefer to make the cables themselves, the required parts (except for
the RS-232 connector for the FUP1010WP flow meter types) should be available at most
computer or electronics stores. You will find drawings of the terminations for these cables
with the reference table below. It provides the signal names, PC termination and SITRANS F
1010 flow meter termination for each type of flow meter.
