Operating LED Indicators
After completing the installation and powering on the CPU/Basic Module and the PC system, check the two-digit
LED display on the CPU/Basic Module. These LEDs show the results of the system self-diagnostic tests, which
are run by the CPU/Basic Module after startup.
The CPU/Basic Module will first test the ROM and RAM of itself, and then UART/Extensive Module(s) if present.
If any error is found, the LED display will show one of the messages described in “Troubleshooting” chapter.
If the first test passes, the CPU/Basic Module will display “Ld”, and wait for firmware to load from the Intellio
C320Turbo/PCIEL Control Board. After loading the firmware, the CPU Module will scan for the number of UART
Modules and the number of ports available. The LED will show the last accessible port.

C320Turbo/PCIEL Hardware Installation
2-7
CPU Module
The left digit shows the UART Module number and the right digit shows the last port number within a UART
Module. The UART Module closest to the CPU Module is number 1. The next module is number 2, and so on. For
example, if “48” is displayed, it means that the last accessible port is the eighth port of the fourth UART Module.
Basic Module
The left digit shows the number of 8-port unit that configured (if continuous 8 ports are considered as an 8-port
unit) and the right digit shows the last port number within an 8-port unit. For example, if “48” is displayed, it
means that the last accessible port is the eighth port of the fourth 8-port unit.
To see a particular port’s line status, you can keep pressing Module Button and Channel (Port) Button till the
desired port is shown on LED display, then look at the seven indicators TxD, RxD, DTR, DSR, RTS, CTS, and
DCD. This provides a convenient diagnostic ways for Intellio C320Turbo/PCIEL. Normally, DTR and RTS
indicators will light on when local port is opened while DSR and CTS indicators will light on when remote port
is opened. TxD indicator will light on if local port is transmitting data and RxD indicator will light on if local port
is receiving data (or remote port is transmitting data). DCD indicator is mostly useful to detect phone line
carrier when a modem is connected to the port.
Mix of Various UART Modules
UART Modules with various functions are produced for different requirements, such as RS-232/RS-422,
female/male DB25 connector, isolation protection or surge protection.
No matter what interfaces they use, any two UART Modules could be mixed (connected) together freely
depending on needs. For example, you may put 2 male RS-232 UART Modules and 2 female RS-422 UART
Modules together for application consideration.
