1.3.14 Scale (Bedded Models Only)
The scale communicates with the main processor via RS-485. (Refer to Figure 1-16 .) The connector for the
scale cable is in the probe panel housing. The scale is powered by 12V DC supplied by the control board.
The power circuit includes over-current protection.
1.3.15 SpO

The Pulse Oximetry (SpO
2
) option utilizes an OEM module commonly used in other monitoring equipment.
For units that have the SpO
2
option, the SpO
2
patient probe connects to the SpO
2
module which is located
in the probe panel housing. (Refer to Figure 1-17 .) The probe panel housing contains the OEM module and
an SpO
2
interface board. Oximetry parameters and alarms are passed to the main application processor
via serial communication. The OEM module output is communicated to the user visually or audibly as
required.
