SynScan (TM) cable break easily repaired with a network cable

A simple network cable and firmware update got an old SynScan working again.
Problem:
With a used EQ5 Go-To mount and an old handheld, the handheld was giving intermittent and illogical error messages (like "Stand-Alone Use?"). After powering it on and off several times, it only worked sporadically.

Solution:
To ensure the EQ5 was working properly, we connected a different handheld. And lo and behold, the mount worked without a hitch. It quickly became apparent that the old handheld had outdated firmware and a loose cable.

New Cable
To be absolutely sure that the cable was the problem, we tried a different one, which made the handheld work flawlessly.
Tip: Unfortunately, the loose connection on the connectors or cables is often not visible. Past experience has also shown that soldering or clamping only provides temporary relief.

Another alternative: You can replace the defective cable with a standard network cable. Network cables are available in different lengths and colors, as well as in different degrees of flexibility (short, long, rigid, or ultra-flexible). The network cable works immediately and offers more flexibility for individual preferences.
