7.5 Module Inter faces
7.5.1 USB Interfaces
The CP-RIO3-04 rear transition module provides two standard, type A, USB 2.0 connectors, J11 and
J12, on the front panel.
7.5.2 VGA Interface
The CP-RIO3-04 provides one standard VGA interface for connection to a monitor. The VGA interface is
implemented as a standard VGA connector, J7. on the front panel.
7.5.3 Gigabit Ethernet Interface
The CP-RIO3-04 provides two Gigabit Ethernet interfaces realized as RJ-45 connectors without LEDs.
The interface provides automatic detection and switching between 10Base-T, 100Base-TX and
1000Base-T data transmission (Auto-Negotiation). Auto-wire switching for crossed cables is also sup-
ported (Auto-MDI/X).
7.5.4 COM Interface
The CP-RIO3-04 rear transition module provides two identical COM ports for connection to RS-232 de-
vices. On the 8 HP version, the onboard 10-pin serial connectors J2 and J3 are routed to the 9-pin D-
Sub COM connectors J2a and J3a located on the front panel. On the 4 HP version, the COM signals are
available only on the onboard 10-pin serial port connectors J2 and J3.
The following table provides pinout information for the onboard serial port connectors J2 and J3. Refer
to the module layout for connector and pin locations.
