3. Getting Started
This section provides a brief overview of the CPM's basic capabilities, and describes tests that
can be performed to determine if the unit is operating properly.
3.1. Communication Parameters
The Setup Switches, located on the CPM Back Panel, are used to select default settings for all
CPM RS-232 ports. A label located adjacent to the Setup Switches summarizes switch
functions.
When the CPM is shipped from the factory, the Setup Switches are configured for 9600 baud, 8
Bits-No Parity, DTR handshaking, verbose command response, and no echo (all switches
down).
For the purpose of this overview, use the default Setup Switch configuration. Set your
communications program (e.g. ProComm) to use the following parameters:
·9600 Baud
·8 Bits, No Parity
·DTR Handshaking
·Full Duplex
Using Other Parameters (Optional): If desired, the CPM can be set to match the parameters
used by the communications program. Refer to the label on the bottom of the CPM, and
configure Setup Switches accordingly. After changing the Set-Up Switches, initialize the
CPM; press and hold the SET and CLEAR keys, release CLEAR, and then release SET.
Note:
Section 4.1 describes procedures for setting the CPM to match the parameters
used by your communications program.
If Setup Switches are changed, the new configuration will not take effect until the
CPM is initialized.
3.2. Connecting your PC to the CPM
In order to set-up the unit, a PC must be connected to Port 1. Port 1 is always used for
communication during set-up. This is because Port 1 is the only CPM port that will allow
access to all commands when the unit has been initialized to the default state.
Note that after the unit has been installed and configured, other CPM ports can also be granted
access to all CPM commands. This allows any CPM port to function as a "Control Port" after
configuration is complete.
