Installation:
The A-PNL-AUX96-3 auxiliary connector can be used to connect the Telex IP-224 to a Codan Base Station with an
AC-3E or CI-BC-4E, as shown in Figure 1. Ensure jumpers JU67A (or JU67X for CI-BC-4E) and JU68 are installed
on the AC-3E and CI-BC-4E. On Codan MT-4 modules the CTCSS to Subtone connection is not required (CTCSS
is generated internally by the transmitter).
