15 PCM-3343 User Manual
Chapter 2 H/W Installation
Four serial RS-232 ports in two 20 pin connector (CN7&CN12), and one serial port
RS422/485 in 4 pin connector (CN6).
They provide connections for serial devices or a communication network. You can
find the pin assignments for the COM port connector in Appendix.
2.10.1 Serial Port RS-422/485 (CN6)
CN6 can be configured to operate in RS-422 or RS-485 mode by J2.
2.11 GPIO Connector (CN9)
The board supports 16-bit GPIO through GPIO connector. The 16 digital inputs and
outputs can be programmed to read or control devices, with each input or output
defined. Refer to Appendix for detailed information on the pin assignments and pro-
gramming guide.
2.12 IDE Connector (CN10)
The board provides 1 IDE channel which you can attach up to two enhanced Inte-
grated Drive Electronics hard disk drives or CDROM to the board’s internal controller.
This advanced IDE controller supports faster data transfer up to UDMA 33.
2.12.1 Connecting hard drives
Connecting drives is done in a daisy-chain fashion. If you want to use IDE Hard
Drives, please purchase an additional 44 PIN IDE cable (Advantech’s p/n:
1701440350) that can connect to 1.8" and 2.5" drives.
1. Connect one end of the cable to the Hard Drive connector. Make sure that the
red (or blue) wire corresponds to pin 1 on the connector, which is labeled on the
board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on
the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the connector.)
If desired, connect a second drive as described above. Unlike floppy drives, IDE hard
drives can connect to either end of the cable. If you install two drives, you will need to
set one as the master and one as the slave by using jumpers on the drives. If you
install only one drive, set it as the master.
2.13 LAN Connector (CN24 & CN11)
Ethernet configuration
The board is equipped with two high performance 32-bit PCI-bus Ethernet interface
which are fully compliant with IEEE 802.3 10/100Mbps, and supported by all major
network operating systems.
Note! The Input power from external device cannot exceed 3.3 V.
Note! When you using CF socket , the IDE connector only be attached to one
IDE device.
