5 General Description
The RTM311 is a 3U VPX Rear Transition Module. It is intended to be used in combination with
certain 4DSP’s Xilinx FPGA VPX boards, typically VP881. The board implements features that
are required to bring several interfaces of a VPX board to the rear panel. Some of those interfaces
are: USB2.0, USB3.0, DisplayPort, Gigabit Ethernet and SD card. The board also carries a M.2
SSD card that communicates to the VPX through SATA or PCIe.
The global architecture of the RTM311 is shown in Figure 1.

6 Installation
Requirements and handling instructions
•The RTM311 is not hot-pluggable and must be installed in a system that is switched off
•The RTM311 must only be installed with an appropriate VPX board such as VP881
(Contact Abaco Systems for options)
•Prevent electrostatic discharge by observing Electro Static Damage (ESD) precautions
when handling the card
7 Hardware Specifications
This section describes all hardware specifications of the RTM311.
7.1 Physical specifications
7.1.1 VPX connectors
The RTM311 is a 3U VPX Rear Transition Module that has VPX connectors fitted as specified
below:
- VPX RP0: TE connectivity, 1410968-3 is fitted by default.
- VPX RP1: TE connectivity, 1410975-3 is fitted by default.
7.1.2 Backplane keying
Both alignment key1 and key2 are placed by default with the un-keyed version (1-1469492-9).
Contact Abaco Systems if specific keying is required.
7.1.3 Front panel
RTM311 provides various interfaces via the front panel. See section 7.5.2 for more details. The
front panel bezel options are offered as shown below.
•0.8-inch (IEEE 1101.10 and VITA 46 compliant)
•1-inch (IEEE 1101.10 –VITA 46)
•1-inch –VITA 48.1 (as per VITA 65)
It is recommended that the front panel bezel is to be chosen in compliant with the connected VPX
board’s bezel.
NOTE that the RJ45 connectors will only support 1000BASE-T. The ethernet phy’s are hard
configured to 1000BASE-T and will not negotiate with a 10/100BASE link. This is done because
the RJ45 connectors form a bridge to access the VP881 VITA46.6 UTP-1 and UTP-2 interfaces
which only support 1000BASE interface speeds according to the VITA standard.
Make sure to always connect the two RJ45 ports of RTM311 to a 1000BASE-T LAN
connection.

7.2 ESD Protection
The front panel connectors have ESD protection compliant to IEC 61000-4-2, ±15kV (air), ±8kV
(contact).
7.3 Switches
On-board switches can be identified by the silkscreen.
7.3.1 “RESET” button/momentary switch
“RESET” button (SW1) is made assessible on the front panel, through a small key hole. The VPX
board can be reset by pressing this button.
7.3.2 On-board dip switches
Their functionalities are explained below. All switches are in “ON” position by default, apart from
SW4 which should be “OFF” by default.

7.3.3 I2C switch
The I2C interface connects to I2C Master signals that come from the VPX connector pins:
- LOCAL-I2C_SCL: see section 7.5.1.
- LOCAL-I2C_SDA: see section 7.5.1.
It’s called a LOCAL I2C interface, to differ from the SMBus interface on VPX RP0.
The VPX I2C signals connect directly to a I2C level translator PN: TCA9517DGKR, and then to
Texas Instruments part: PCA9548ABS_118. The I2C interface diagram is shown below.
