Rs 232 Data Output - Mallinckrodt INOmax DSIR Plus MRI Operation Manual

RS 232 Data Output

Enables serial communications for use with hospital electronic health record (EHR) system. Must be
connected to the manufacturer-specified third-party hardware.
• Do not use the RS 232 data output while in the MR scanner room.
WARNING:
• INOmax DS
- Four kV input to output isolation
- Four kV input to mains isolation and
- an internal "reference voltage" "U" (as defined in section 20.3 of IEC60601-
• RS 232 cables must be shielded. The RS 232 cable shield shall have a minimum
of 90% coverage. The shield shall only be connected at one end of the cable to
minimize noise induced by ground currents.
• Connector retention jack posts can be found at the INOmax DS
Note:
232 interface cable/connector should be constructed to include cable retention fasteners to help
ensure a robust connection.
• This serial communication protocol requires INOmax DS
higher to function. The software revision of the device can be accessed by pressing the Menu
Button on the Main Screen and then the Settings Button.

isolation certified in accordance with IEC 60601-1. Interface cabling must not
go outside of the room (e.g., into walls where potential isolation issues could
exist). Adherence to the above provide compliance to clause 20.3 "Value of
test Voltage" in edition two and clause(s) 8.5.4 "Working Voltage" and Clause
8.8.3 "Dielectric Strength" in edition three.
Description
Cyclic Redundancy Check
RS 232 (Recommended Standard 232) is the traditional name for a
series of standards for serial binary single ended data and control
signals connecting between a DTE (Data Terminal Equipment) and
a DCE (Data Circuit-terminating Equipment).
