The FloSI card
About the FloSI card
The FloSI (Serial Interface) card provides an SDI-12 or ModBus output to interface an XCi device to SCADA
systems. This card provides unconditional polling access to the most recent user configured measurement
results of XCi devices.
NOTE: Only one FloSI per XCi device is supported
RS-232, RS-485 and SDI-12, interfaces are available from the XCi device with the use of a FloSI. The FloSI
enables users to request the last measurement from The XCi device without the complexity of
communicating via the host communications port.
The FloSI cannot be used to download or configure a XCi device, and only one serial protocol may be used at
one time.
Wiring a FloSI card
After installing the FloSI card (see Installing FloSeries3 Cards ), connect it to the remote device using either:
1. The 9-pin d-connector (RS232, ASCII or RS232 ModBUS) for RS232;
WARNING: Depending upon the type of remote device, a null modem cable
may be required for RS232 communication.
2. The 4-way terminal block for RS485 ModBUS mode;
3. The 3-way terminal block for SDI-12 mode.
