Connection with a Reichert Digital Refraction System
The ClearChart 4 can directly connect to a Reichert digital refraction system, using a cable
or wirelessly connected using a Bluetooth serial adapter. Wired communication between the
ClearChart 4 and the digital refraction system requires connection of a cable between the serial port
on the ClearChart 4 and the digital refraction system.
Bluetooth Connection
Wireless communication between the ClearChart 4 and a Reichert digital refraction system requires
connection of a Bluetooth device. Either a USB Bluetooth adapter (PN 13779) can be used, or a
Bluetooth serial adaptor (PN 16251) powered by the USB port or with a separate AC adapter.
If using the USB Bluetooth adaptor (PN 13779), install the Bluetooth into one of the USB ports on the
bottom of the ClearChart 4. Refer to Figure SU-20.
