15 Appendix — Configuring Communication Connections

15.1 Legacy Serial Communications Driver Installation

The instrument supports two modes of communication "Legacy" and "GA5K". At present the instrument
communications software will only communicate in the "Legacy" communications mode.
IMPORTANT: Irrespective of operating system, the instrument will need to be set to Legacy
communications mode. The drivers will need to be installed using a Windows login account with
administrative privileges. If more than one instrument is connected to the computer, it will automatically
install the software for the second instrument because an administrator has already installed it initially.
Each instrument on a given computer will have a unique COMxx port assigned to the instrument. COMxx
port assignments are unique to the computer and not to the instrument. This means the one instrument
may be COM17 on a desktop computer and COM6 on a laptop computer.
