the Apollo HMI via the Apollo Sub-System RS-485 Communication port. Apollo also supports
an interface for the following downhole tools:
•
Zenith E-Series Sensors using ZIU or the Zenith Surface Panel
•
GRC Tools using SPS1500 or Scout 3000 panels
•
Centinel
By default, the “Standard” template is pre-configured for the Osiris Downhole Sensor displaying
pressures as PSI and temperatures as Degrees F. To remove Osiris, interface with a different
sensor, or to change engineering units for downhole channels, See Section 5.2 Setup a
Downhole Tool, page 127.
The Osiris Downhole Sensor Interface (DSI) Assembly is only required for ESP
applications that employ a Baker Hughes Osiris Downhole Sensor. It is not required in
applications that do not employ a Downhole Sensor. It cannot be used as an interface
to Downhole Sensors manufactured by others.

The switches on the DSI are as follows:
