3.12 Additional Features and Information

The following sections contain information on additional features of the OEM7 receivers.

Strobes

below

3.12.1 Strobes

The CPT7 has three EVENT inputs and three EVENT outputs that provide status and synchronization signals.
These signals are also referred to as strobes. For detailed information about CPT7 strobes, see

CPT7 Strobe

Specifications

on page 176.

By default, the EVENT3_OUT signal is configured as a Pulse Per Second output.
