USING THE CRAFT PORT TO SETUP THE MA-490
INTRODUCTION
This section contains information on how to set up the MA-490 module.
ESTABLISHING COMMUNICATIONS
A user can communicate with the MA-490 through the Craft port on the rear panel of the module.
Either a PC or laptop equipped with terminal emulation software such as HyperTerminal or Procom
can be used for communication. Once connected, APRIL (Asynchronous Programming and Remote
Interrogation Language) can be used to view the configuration parameters of the MA-490. Because
APRIL is menu based, memorization of commands is not required. Help screens can always be
displayed by pressing the [H] key.
PHYSICAL CONNECTIONS
The Craft port on the MA-490 is typically connected directly to a PC or laptop using a standard
(straight-through) connector as shown in Figure 10. The Data port of the MA-490 is connected to the
Common Module or other external equipment using a null modem cable as shown in Figure 11.
