Serial Port Scanning
The Scan Function is provided to assist the user when they are unsure which communication port the MDR210A-485 is attached to or what baud rate it has been set to. The Scan Function will attempt to communicate with the MDR210A-485 over every port installed on the PC at every allowed baud rate. While this is not a fast process, it does allow the recovery of a device whose configuration is unknown. If the Scan Function is unable to determine the port which the MDR210A-485 is attached to, the user will be notified. The user should then ensure that no other application has the communication port in use before re-attempting the Scan.
Application Fields
COM Port - Specifies which PC communication port the MDR210A-485 to be configured is attached.
Scan - The scan function iterates each available PC communication port looking for an attached MDR210A-485. If an MDR210A-485 is found, its COM Port and current Baud Rate values are provided.
Network ID - All communicating MDR210A-485s must be programmed to the same Network ID. The valid values are from hexadecimal 1 to FFF.
Hop Table - All communicating MDR210A-485s must be programmed to the same Hop Table. The valid values are 0 to 6. Independent networks in the same vicinity should use different Hop Tables to minimize packet collisions.
Baud Rate - This is the desired communication Baud Rate between the host and the MDR210A-485.
Setup - Send the currently selected values to the MDR210A-485 attached to the specified communication port.
Close - Exits the Application.
Networks
There are seven available networks (Hop Tables). Each network utilizes a different pseudo-random hopping sequence to navigate through the shared hopping channels. In the event that two modules from different networks collide on a channel (because they
