PCM-9377 User Manual 20
2.14.1 CRT display connector (CN17)
The CRT display connector is a 15-pin D-SUB connector used for con-
ventional CRT displays.
2.14.2 Flat panel display connector (CN13)
CN13 consists of a 40-pin connector which can support a 24-bit LCD
panel with Hirose connector no. DF13A-40DP-1.25 V. The board pro-
vides a bias control signal on CN13 that can be used to control the LCD
bias voltage. It is recommended that the LCD bias voltage not be applied
to the panel until the logic supply voltage (+5 V or +3.3 V) and panel
video signals are stable. Under normal operation, the control signal
(ENAVEE) is active high. When the PCM-9377’s power is applied, the
control signal is low until just after the relevant flat panel signals are
present. CN13 can connect up to 24 bit TFT LCD.
2.14.3 Extension flat panel connector (CN15)
CN15 consists of a 20-pin Hirose’s connector no. DF13A-20DP-1.25V.
The PCM-9377 supports a 36-bit LCD panel which must be connected to
both the CN13 (40-pin) and the CN15 (20-pin). The pin assignments for
both CN13 and the CN15 can be found in Appendix C.
2.14.4 LVDS LCD panel connector (CN14)
The board uses VIA Mark chipset that supports 2 channel (2 x 18 bit)
LVDS LCD panel displays. Users can connect to either an 18-bit or 36-bit
LVDS LCD with CN14.
2.15 Ethernet configuration
The board is equipped with two high performance 32-bit PCI-bus Ether-
net interface which is fully compliant with IEEE 802.3U 10/100Mbps
standards. It is supported by all major network operating systems.
2.15.1 100Base-T connector (CN24)
100Base-T connections are made via one RJ-45 connector and one inter-
nal 10-pin box header.
2.16 Watchdog timer configuration
An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu-
able protective device for standalone or unmanned applications. Setup
involves one jumper and running the control software.
