  • Page 122 SPECIAL FUNCTIONS Change ELI-Link Timeout This function was added to software v2.4.2 in order to optimize the time delays that can occur when communicating to a facilities network. The default wait-time is 60 seconds, before the cardiograph will stop listening for a response from ELI-Link once a communication request is sent. This feature allows the wait-time to be adjusted to a different duration, depending on the typical response time of the particular network environment.
