3.3.4 Remote LEDs and Recovery Switch
The PTP 400 Series Bridge PIDU Plus provides a facility to connect remote LEDs and
Recovery switch allowing the PIDU Plus to be mounted inside an enclosure. At the left end of
the PIDU Plus under the ODU connection cover can be found three jumpers and a PCB
header. Jumpers J906 and J907 should be removed and connection to the remote LEDs and
Recovery switch made to J908 as shown in Figure 9.

3.3.5 Cables and Connectors
The cable used to connect the PTP 400 Series PIDU Plus to the ODU can be any standard
CAT 5 type provided that it is suitable for outdoor deployment. Motorola recommends that
cables to the specification below be used.
NEC/CEC: CMR (ETL) C (ETL) 75C SUN RES OIL RES II
Failure to use the recommended (or equivalent) standard of cable may invalidate the
system’s safety certification.
The PIDU Plus/ODU cable may be unscreened (UTP) or screened (STP). However,
unscreened cables reduce the system’s ability to cope with nearby lightning strikes. If
lightning activity is common in the area of deployment, the use of screened cable is highly
recommended. See Section 11 “Lightning Protection”.
