10: Configuration Pin Manager
There are 11 configurable pins on the XPort AR. All CPs (except for 5) are shared by some other function on the XPort AR. Some of the CPs are assigned to serial port 1 (dtr/dsr for modem control and rts/cts for hardware flow control), others to serial port 2 (dtr/dsr for modem control, rts/cts for hardware flow control, and tx/rx groups as well).
CPs are configurable individually, or may be clustered together and configured as a single group (CP group). This increases flexibility when incorporating the XPort AR into another system.
Each CP group is a 32 bit variable. When a CP is added to a CP group, it is assigned to a bit position within the group. A CP cannot be assigned to a group until it is configured. A CP can be a member of multiple groups, but may only be active in one.
The Configurable Pin Manager (CPM) is available through the Web Manager (see Configuration Using Web Manager on page 17) or through Command Mode (see Configuration Using Telnet or Serial Port on page 66).
Configurable Pins
To view a CP’s configuration:
1.If using the Web Manager:
a)Click CPM Æ CPs from the navigation menu. The CPM: Configurable Pin window displays.
b)Click the specific CP from the Current Configuration table. The CP’s configuration displays in the CP Status table.
2.If using Command Mode (the CLI):
a)Enter Enable Æ CPM to access the CPM level menu.
b)Type show cp.
3.The CP table displays the following:
CP | Indicates the Configurable Pin number. |
|
|
Pin # | Indicates the hardware pin number associated with the CP. |
|
|
Configured As | Displays the CPs configuration. A CP configured as Input is |
| set to read input. A CP configured as Output drives data out |
| of the XPort AR. Peripheral is a setting assigned by the |
| XPort AR. |
