CP3004-SA
6.6.4 Serial Port
One PC-compatible, serial RS-232 port (COMA) is available, which is fully compatible with the 16C550
controller. This port includes a complete set of handshaking and modem control signals. Data transfer
rates up to 115.2 kB/s are supported. The serial port is implemented as an 8-pin RJ-45 connector, J8.
6.6.5 CFast Interface
To enable flexible flash expansion, a standard CFast card socket, J4, is available on the 8 HP CP3004-
SA with CP3004-HDD. However, the 12 HP CP3004-SA does not provide CFast card support.
6.6.6 SATA Interface
The CP3004-HDD extension module provides two SATA connectors, one 29-pin standard SATA connec-
tor, J6, for connection to 2.5” SATA HDD/SSD, and one 60-pin, standard high-speed I/O extension con-
nector, J4, for connection to the SATA adapter module, which enables the installation of an additional
2.5” SATA HDD/SSD. The SATA adapter module, expands the CP3004-SA to 12 HP.
