1.5 Verify / Set the TCT Port Offset If Configuring a B573 MBX TCT Router

If a B573 is installed at a property that uses TCT room gateway devices, the TCT devices are supposed to
communicate with the B573 over the Ethernet network using a default "TCT Port" value of "23210". 23210 is the
TCP/IP network port# that the B573 and the TCT's communicate over.
The B573 MBX supports changing this TCT Port value by adding an offset value to the baseline value of 23210.
This is done to allow more than one B573 MBX to be used on the same network. However using more than one
B573 MBX is only done under special rare circumstances. This "TCT Port Offset" value stored in the B573 MBX
should ALWAYS be set to "0", which then sets the actual TCT Port to 23210 (ie baseline 23210 + offset 0 =
23210) . The "TCT Port Offset" value is stored in the "non-volatile" memory ( NVRAM) of the B573 MBX at
NVRAM Offset "16".
Use the following steps to verify the B573 TCT Port Offset value is set to "0". This procedure leads you through
entering the B573 "manufacturing" menu, then selecting NVRAM offset 16 to view the current TCT Port Offset
value.
