6.15 Firmware upload of CST and PRA-ANS with static IP-addresses
A firmware upload of the PRA-CSLx Call stations and PRA-ANS Ambient noise sensors
produced with firmware prior to V1.60 will fail if the devices are set to static IP.
For every firmware upload of these devices, you must:
1. Change the static IP-addresses of the devices to a DHCP- or link-local address.
2. Update the devices to the new software version.
– You can now change the DHCP-addresses to static IP-addresses.
