Remapping Baud
Rates This option allows you remap the 300, 600, 1200, and 2400 baud rates to more
useful values. A common use of this option is to enable an application to use a
higher baud rate than is otherwise available.
Once a value is placed in one of the mapped fields, whenever an application selects
the mapped rate, the alternate rate is used instead. For example, if you map 300
to 115200, then select 300 baud in an application, the actual baud rate used is
115,200.
Follow these steps to remap baud rates:
1. Access the System Properties window. (Either double-click on the Control Panel
System icon or right-click on the My Computer icon and select Properties.)
2. Select the Device Manager tab.
3. Double-click on Multi-function adapters.
4. Select the RocketPort/RocketModem and click Properties.
5. Select the Board Options tab.
6. Click the Advanced button. The Advanced Board Options window appears:
7. In the Baud Rate Mapping section of this window, select the rate you want to
remap.
8. Use the droplist to select a new baud rate, or type in a value.
Note: See the Hardware Installation Card to determine which baud rates are
supported by your adapter.
9. Repeat Steps 7 and 8 as required.
10. If necessary, set the scan rate as described in Scan Rate on Page 17. In order
to use a Scan Rate faster than 10 ms, the Use IRQ box must also be checked.
Note: Typically, you should leave the scan rate set to the default value (10 ms)
for most applications. Only change the scan rate if you are experiencing
performance bottlenecks. If you go lower than 10 ms, it may affect
overall system performance.
11. Click Done to save your changes and return to the Board Options window.
