Serial Signal Level Shows the status of the following parameters related to the host signal level:
• DCD—Data Carrier Detect—Control signal to the PC
• DTR—Data Terminal Ready—Used to establish a connection
• DSR—Data Set Ready—Used to establish a connection
• CTS—Clear to Send—Data flow control
• RTS—Request to Send—Data flow control
Each parameter can have a value of LOW (signal not asserted) or HIGH (signal being
asserted).
The first three parameters (DCD, DTR, and DSR) may be helpful for troubleshooting. If the
values shown for these parameters are not as expected:
1. Press Refresh to ensure you have the latest values.
2. Check the cable connections.
Note: ACEmanager does not update dynamically. Press Refresh to view the current
values.
I/O X-Card Serial These fields apply only to GX Series devices with an I/O X-Card installed.
I/O X-Card Serial
Reserved by External
Application
This field displays the reservation status of the I/O X-Card serial port.
• ON—The serial port is reserved for ALEOS Application Framework (ALEOS AF), and
cannot be used for any other serial-related ALEOS features.
• OFF — The serial port is available for non-ALEOS AF, serial-related ALEOS features.
To reserve the serial port for ALEOS AF, go to Applications > ALEOS Application
Framework > Serial Port Reserved. (See ALEOS Application Framework on page 250.)
I/O X-Card Serial Port
Mode
Default power-up mode for the I/O X-Card serial port. When the AirLink device is power-
cycled, the serial port enters the mode specified by this command after 5 seconds.
I/O X-Card Serial TCP
Auto Answer
This parameter determines how the AirLink device responds to an incoming TCP
connection request on the I/O X-Card serial port. The AirLink device remains in AT
Command mode until a connection request is received. DTR must be asserted (S211=1 or
&D0) and the device must be set for a successful TCP connection. The AirLink device
sends a “RING” string to the host. A “CONNECT” sent to the host indicates
acknowledgment of the connection request and the TCP session is established. Options
are:
• Disabled (Default)
• Enabled
I/O X-Card Serial UDP
Auto Answer
Enables UDP auto answer (half-open) mode on the I/O X-Card serial port
• Normal mode
• Enable UDP auto answer mode
I/O X-Card Serial
bytes sent
Number of bytes sent over the I/O X-Card serial port to host
I/O X-Card Serial
bytes received
Number of bytes received over the I/O X-Card serial port from host
