Versions history of the RS2IPVIS software available on this site:

v1.8

• improvement – ping queries issued at program start for each defined camera will timeout only after 4 × 1 second(s) (re)tries
• improvement – in case two USB to serial adapters are used for serial camera controllers, by disconnecting one of them, the other one and its associated serial connection is no longer affected
• bug fix – broadcast Address Set response was not consistent in case one of the defined cameras was switched OFF

v1.7

• bug fix – broadcast Address Set response was not consistent in case of using Visca Camera Controller software joystick controller

v1.6

• bug fix – response packet bytes were altered at random in case some non-VifuLens IP to serial converter would be used for PT(Z) control at camera side – like, for example, the WIZ110SR from Wiznet

• bug fix – better error handling in case some associated VifuLens interface is disconnected and then reconnected back to network
