Hi Ali,
If you bought an EQMOD cable, that will allow you to connect your mount directly to your computer and control it from there using software such as NINA, SequenceGeneratorPro or KStars (depending on whether you have Windows, Linux or macOS installed).
Somewhere I have an old USB to RS-232 adaptor with the DB9 plug. I'm happy to lend it to you, but you'd need to find a DB9 to (whatever) adaptor for your SynScan controller.
Cheers,
V
