9.2.4 The number of TCP-IP connections
The IMP supports up to eight simultaneous TCP-IP connections (eight logical ports).
To maintain optimal system accessibility, it is advisable to issue “port-open” and “port-close” commands
before and after command or query strings are issued. This approach enables eight or more control devices
to be effectively interfaced simultaneously and without concern for communication errors.

Note:
As a safeguard, the IMP incorporates a 30-second timeout window for each port. If any port is inactive for
more than 30 seconds, it will be closed automatically.
