Phase 4 Design is dedicated to the support of the Telex Radio Dispatch System. In order to do that we design and build custom interface adaptor cables and radio enclosures for our customers. Several of our designs have been standardized and are offered for sale below. If you don't see what you need, please call us, we would be happy to work with you to produce a custom solution.


IP-223 to IP-224 Upgrade Adaptor

The IP-223 to IP-224 Upgrade Adaptor is used to quickly upgrade an IP-223 to an IP-224 without changing the radio interface cables or building custom wiring. This adaptor has a DB37M on one end that connects to the IP-224, the other end has DB25F and DB9F connectors that mate directly into the existing radio interface wiring.

Using this cable allows an inplace IP-223 to IP-224 upgrade to be done in minutes without any changes to the radio interface cables. Just mount the IP-224, connect the cables and set levels, that is it!

If the IP-223 going End of Life is requiring you to upgrade your IP-223s to IP-224s and you don't need to change any radio interface wiring, this is just the thing for you.

By using the IP-223 to IP-224 Upgrade Adaptor to do an inplace upgrade to an IP-224, your system is back online quickly with no surprises. This gives you time to design and build any new radio interfaces as you upgrade your radio system.
