When in delimiter mode, the ToolLink Gateway uses start and stop delimiter strings to identify the beginning and end of a message packet. The Start Delimiter String parameter defines the beginning of a message, and the Stop Delimiter String parameter defines the end of a message. MKS Instruments, Inc. Page 7 of 30... -
