Instrument Setup

EMR Setup
The Visutron 900 Touch can connect to an EMR system one of two ways, depending on the capability of
the EMR system. Contact the EMR company to find out if the specific EMR system is configured to sup-
port one-way or two-way communication.
One-Way EMR
One-way communication means the EMR system can only accept data coming in. This configuration re-
quires pre-test equipment to send data to the Visutron 900 Touch , then all of the data (the pre-test data
and final refraction data) would transfer to the EMR. Refer to Figure IS-23.

Note: If there are multiple lanes with Visutron 900 Touch systems, they will need to be connected via
daisy-chaining. This will allow all pre-test data to be transferred to each Visutron 900 Touch
system. From there, each Visutron 900 Touch can load the pre-test data and send all of the data
to the EMR system. Refer to the Daisy chaining Multiple Visutron 900 Touch’s section for more
detailed information on this setup.
Two-Way EMR
Two-way communication means the EMR can send pre-test data out to the Visutron 900 Touch and
receive final refraction data in from the Visutron 900 Touch . At the end of the exam, the Visutron 900
Touch will send only final refraction data out to the EMR. Refer to Figure IS-24.
