The Four Slot Dock 7-13
2325A137REFGD Revision B 2325 Reference Guide
Setting the Baud Rate
The 4-Slot Dock is capable of operating at the following baud rates:
9600
19200
38400
115200
It is configured for 19200 baud at the factory.
When running in host-controlled mode, the 4-Slot Dock network must be
informed of the baud rate the host and 2325s will be using and 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. You will need a host-communications
software package, such as ProCOMM or HyperTerminal. 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 your host-communications package or program to 2400 baud.
Send a single space to the dock network. You will not get any
feedback from any of the 4-Slot Docks in the dock network.
Note: This step isn’t always necessary, but it ensures that the
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.
2. Now set your 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.
Note: You can type in the command at a terminal
communications program, send it out the COM port from
an application, or copy it to the COM port device driver
under DOS.
You should receive the unit IDs in brackets (i.e., [Unit ID])
from any 2325s in dock slots. For each empty slot in the dock
