OEM version

DB9 to RJ45 converter

Ira-3 has a standard RJ45 connector. This makes cabling a lot more flexible. You can either purchase a RJ45 to DB9 cable from us, or you can purchase RJ45 to DB9 adapter (shown on the right) and use a required length of CAT5 cable. This approach is also beneficial if you want to run the cable through the walls. DB9 connectors are rather bulky and hard to route through narrow space. Instead you can run CAT5 cable through the wall (or use an existing wiring) and connect Ira3 on one side and DB9-RJ45 adapter on the other side.
