Setting the Baud Rate
The Falcon 4-Slot Dock is capable of operating at the following baud rates:
z
9600
z
19200
z
38400
z
115200
It is configured for 19200 baud at the factory.
When running in host-controlled mode, the Falcon 4-Slot Dock network must
be informed of the baud rate the host and portables will be using so that it can
set itself accordingly.
To enable the 4-Slot Dock network to detect and set the baud rate, follow the
procedure below. A host-communications software package, such as
ProCOMM or HyperTerminal is required. It does not matter if the portables
have the
4slot.sys
driver loaded. However, each portable must have the
4slot.sys
driver loaded if the host is to control that portable.
Complete the following steps.
1.
Set the host-communications package or program to 2400 baud. Send a
single space to the dock network. There will not be any feedback from
any of the Falcon 4-Slot Docks in the dock network.
2.
Now set the host communications package or program to the desired
baud rate and send a plus character (
+
) to the dock network. This is a
synchronization character that the docks use to verify that they are
correctly getting data from the host on a baud rate change.
3.
To verify that the docks are correctly configured, send the
Request
Unit
IDs
command
DCRI
to the dock network.
This step isn’t always necessary, but it ensures that the Falcon 4-Slot Docks will
detect a baud rate error as quickly as possible. It also eliminates concern about what
baud rates the various docks are already in.
