RTI-12309 Getting Started

Overview
This document describes the features of the RTI-12309. You can use the RTI-12309 to
connect to any SLSC module supporting fully compatible rear I/O. The eight 10-pin Hirose
ix Industrial (or equivalent) connectors provide access to up to 8 banks of signals for DIO,
AI, or AO.
NOTE
Before you begin, read the RTI-12309 Safety, Environmental, and Regulatory
Information document on ni.com/manuals and complete the soware and
hardware installation procedures in your chassis documentation.

Installing the RTI-12309
Figure 1 : Installing the RTI-12309 into the SLSC chassis
CAUTION
Do not touch the contacts or remove the I/O boards or cables while the system is
energized.
Complete the following steps to install the RTI-12309 in the chassis.
1. Power o the main DC power source or disconnect it from the chassis before
installing any RTIs.
2. Ensure that the chassis is powered o.
The POWER LED should be o. If it is not o, do not proceed until it is o.
3. Loosen the screws of the upper rear panel of the chassis.
4. Position the RTI-12309 at the desired slot and insert the securing screws, but do not
fully tighten them.

5. Insert an SLSC module into the same slot as its corresponding RTI-12309 while
firmly holding the RTI-12309 in place until the RTI-12309 is firmly connected to the
module.
6. Repeat steps 4 and 5 for all required RTIs.
7. Tighten the screws for all RTIs and the screws of the upper rear panel of the chassis.
This ensures proper alignment for future connections between modules and RTIs.
Connecting JR1
To connect JR1, complete the following steps.
1. Prepare a terminal wire for JR1 by stripping insulation and installing a Molex Ultra-
Fit crimp terminal following the manufacturer's specifications.
2. Insert a prepared terminal into an appropriate terminal socket of Molex Ultra-Fit 8-
position receptacle housing.
3. Repeat steps 1 and 2 for all appropriate terminals.
4. Insert a receptacle housing into JR1 until the plastic retention latch snaps into
place.
JR1 is keyed to prevent reverse installation of the receptacle housing.

NOTE
Column z pins are tied to GND A or B on the RTI-12309, and are designed to contact
an optional lower shield on the SLSC module connector, if the shield is present.
Column f pins are all no-connects (NC) on the RTI-12309, and are designed to
contact the same upper shield on the SLSC module connector. The SLSC module
designer configures these pins as GND A or GND B.
NOTE
JR2-5 (Banks 1-4) are referenced/routed to GND A on the XP2 connector, and JR6-9
(Banks 5-8) are referenced/routed to GND B on the XP2 connector.
