V.24 Port
This port can be used for either synchronous or asynchronous applications. This RJ45 connector and pinout is
the same as used on previous product V.24 boards. This port can also be configured for asyncronous operation.
This port interfaces to SCC1 of the MPC8250.

External 1 PPS
The external 1PPS connector currently resides on the Backplane. It is DC coupled, high impedance input,
accepts 3.3V DC TTL level signals and is 5 Volt tolerant.
External References
There are two external references (Ext_Ref and 5MHz_In). The Ext_Ref signal resides on the Backplane. It
accepts both 5 MHz, 5 MHz / 1 PPS, and 10 MHz references and is DC coupled. The second external reference
(5MHz_In) is located on the front panel behind the fan assembly. It has a 50 ohm input resistance and is AC
coupled. This input will be used to align the OCXO residing on the SAC.
System Connector
The System connector is a 50-pin Mini SCSI connector. It is used for all the Wildcard general purpose inputs and
outputs. It also provides I/O for both MRTI Phone Patch and 6809 Trunking Controller configurations.
