Pin #
Primary Function
CP2/DTR
(Configurable Pin 2)
7
CP2 can be configured as follows:
•
Modem control: DTR (Data Terminal Ready) output
driven by DSTni’s built-in UART for connection to DCD
of attached device.
•
Programmable input/output: CP2 can be driven or
read through software control, independent of serial
port activity.
CP3/CTS/DCD
(Configurable Pin 3)
8
CP3 can be configured as follows:
•
Flow control: CTS (Clear to Send) input read by
DSTni’s built-in UART for connection to RTS of
attached device.
•
Modem control: DCD (Data Carrier Detect) input
read by DSTni’s built-in UART for connection to DTR
of attached device.
•
Programmable input/output: CP3 can be driven or
read through software control, independent of serial
port activity.
Ethernet Interface
The Ethernet interface magnetics, RJ45 connector, and Ethernet status LEDs are all
in the device server shell.
