Quick Start Guide
COME-QEC-1
5.2.2 USB Connectors J3/J4/J14
The COME-QEC-1 provides connectivity for up to five USB-Host ports or four USB-Host ports and one USB-Device port. Connec-
tors J3 and J4 share a common USB port which must be configured either as a host or a device port.
Directly usable:
» J3: USB-Device-Port (USB type B connector)
» J4: USB-Host-Port (USB type A connector)
» J14: Header for connecting a standard USB cable assembly (included with the EVAL-Kit) providing two USB-Host-Ports (USB
type A connectors).
Furthermore, there are two USB host ports routed to the Slot 1 sideband connector (J23) and the Slot 2 sideband connector
(J24). These two ports can be evaluated either by using the connectors on the ADAP-EVAL-QORIQ-SRIO Adapter Card or can be
used by Add-In cards which are specially designed for customer purposes.
Please refer also to the pinout table of connectors J23 and J24 and Chapter 9.3 Adapter Card ADAP-EVAL-QORIQ-SRIO.
5.2.3 Ethernet Connectors J5/J6L/J6R
The COME-QEC-1 provides RJ45 connectors, J5 and J6 Right and Left, for up to three Gigabit Ethernet copper interfaces
(ETH0..ETH2 on connectors J5 and J6). If the carrier is equipped with the COMe-bP5020, only ETH0 (J5) is supported. In con-
figurations with the COMe-cP2020 all three RJ45 connectors are usable for GbE interfacing.
5.2.4 Serial Interface Connectors J7 Upper and Lower
The COME-QEC-1 provides two D-SUB9 connectors for serial UART interfacing. The connector pinout is as follows (depending on
the module and carrier configuration). The configuration of these interfaces for RS232 or RS422 operation is done using DIP
switch SW3 switches 1 and 2.
Table 4: D-SUB9 Ser ial UART Connectors J7 (Upper and Lower) Pinout
For RS422 operation, jumpers J10 (COM0 TX), J11 (COM1 TX), J12 (COM1 RX) and J13 (COM0 RX) are provided for signal line
termination as required.
5.2.5 microSD/SDHC Card Connector J8
The COME-QEC-1 evaluation carrier is equipped with a microSD/SDHC card socket J8 which provides the possibility to extend
the mass storage capability of the COMe-bP5020 or the COMe-cP2020 with an external SD/SDHC card of up to 32GB. This device
can be used as a boot device or for data storage.
Note: This socket is multiplexed with the on-board SD/SDHC card socket of the COMe-bP5020 or COMe-cP2020. Please ensure
that the configuration of the COM Express® module is done correctly for the usage of this socket.
