2 THEORY OF OPERATION

The Programmable Serial Interface Card (PSIC) has 2 ports which can be configured for
RS-232, RS-422/RS-485 Half Duplex or RS-422/RS-485 Full Duplex communications
with external devices. For communications with the F250 Precision Thermometer devices,
any mode may be used. The driver supports only one F250 device per port. Specifically,
the devices cannot be multi-dropped.

The DeltaV Serial Card Driver functionality will be as follows.

1. The driver will be flashed into the PSIC.

2. The driver will run in Master mode only and be responsible for sending commands to
the F250 units. The F250 will respond with temperature reading information, which will be
reported to DeltaV in dataset registers.

3. The two ports of the PSIC work independently, each connected to a single F250 unit.

The following shows PSIC connectivity with F250 Precision Thermometer devices.
