68RTG5 Data Sheet

FUNCTION/FEATURES

• High density connectors mimic 68G5 front panel I/O
• OpenVPX 0.8” (or 1.0” option) pitch rear chassis I/O panel with locking extractor
• Optimized for NAI 68G5 multifunction rear I/O
• Mini-HDMI interface receptacle (utility interface)

DESCRIPTION

The 68RTG5 3U OpenVPX Rear I/O Transition Card (RTC) (also may be referred to as Rear Transition Module or RTM) is for use in OpenVPX systems/chassis that require reliable interconnection between the rear I/O P1 & P2 OpenVPX connectors and the ‘outside world’. The rear I/O P1 & P2 connectors are terminated in two Harwin 50-pin Datamate connectors and a mini-HDMI-type receptacle located on a 0.8” (or 1.0” option) pitch OpenVPX panel. The rear chassis panel has an extractor to latch or eject the card from the rear backplane access panel of the chassis. The 68RTG5 can be used with any 3U OpenVPX card, but pin-outs are optimized for use with, and also mimic, the front panel pin-out of the OpenVPX NAI Model 68G5 Multifunction I/O (MFIO) card. The mating panel I/O connector(s) may be mechanically secured using a screwdriver.

68RTG5 INSTALLATION

68RTG5 CONNECTOR/PIN-OUT INFORMATION

I/O Connectors

User I/O is available through the panel mounted RJ3 & RJ4 RTM connectors, JP2 in-board header connector and JP3 mini-HDMI-type receptacle connector via the VPX P1 & P2 user defined rear I/O backplane connectors. The 68RTG5-x RTM is optimized for use for the 68G5 OpenVPX multifunction I/O card, reference(s) throughout this document may be made to 68G5 part number and pin-out information for the 68G5 Motherboard Manual.

Caution

Do not connect to any undesignated or N/C pins.

Note

The following notes apply unless otherwise specified:

1. Maximum ratings for the Tyco MultiGig-RT2 type rear I/O connectors are as follows (per Tyco 108-2072):
       • 50 V peak AC or 50 VDC
       • 1A @ 30 deg.
2. Signal names are provided for reference (referenced to 68G5 signal names) only.

RTM Panel Connector System Ground Pins

Panel: RJ3 pin 1, 26
     RJ4 pin 25, 50

RTM Panel Connector Chassis Ground Pins

Panel: No dedicated chassis GND pins available.
Once installed and secured within a VPX chassis, the panel itself, rear VPX connector key guides and mini-HDMI-type JP3 debug port receptacle shell are connected to chassis (ground).
