(PTP 600) and 500-04-00 (PTP 500). TDD synchronization (and thus PTP-SYNC) is not supported with PTP 300. CAUTION Do not install the PTP-SYNC unit in a domestic (home) environment as it is a Class ‘A’ product. In a domestic (home) environment, it may cause radio frequency (RF) interference in other appliances. -

PTP-SYNC Installation Guide 5. Installing PTP-SYNC Connecting up PTP-SYNC To connect the PTP-SYNC to the PIDU, ODU, GPS receiver (if fitted), and LPU (if fitted), proceed as follows: Disconnect the power supply from the PIDU. If using GPS, connect the cable from the GPS unit to the GPS/SYNC IN port. -
Page 23: Powering Up And Testing The Installation
System using a GPS receiver module - Ensure that there is a cable connection between the PTP-SYNC ‘GPS/SYNC IN’ interface and the LPU, also that there is a cable connection between the LPU and the GPS receiver module. Check that the GPS receiver module has an uninterrupted view of the sky. - Page 24 The ‘ODU’ LED does not illuminate within 90 seconds of power- This probably indicates that there is no communication between PTP-SYNC and ODU. Ensure that the PTP-SYNC ‘ODU OUT’ interface is connected to the ODU (and LPUs if installed) via the drop cable.
