4.4 Controlling Margay with RS232/RS485

Connect the RS232 In to the computer. Loop thru with RS485.

Remote control with serial commands is a good way to control a wall while it is operating. It’s also an easy way to control Margays in a wall during initial setup using one of the Clarity utility programs.

Cube IDs

When the cubes are connected in a series loop (2.5.4 “Connections, Control: RS232 & RS485” on page 28), each cube should have a unique ID. The ID is set in the Serial Settings menu.

The Group ID and the Unit ID go together to make the cube’s ID. Each of the two parts has a range for characters from 0 to 9 and from A to Z (not case sensitive).

Addressing the cubes

When you send a command, it will have an address. There are five forms of the address.

•To address all the cubes in this serial loop, use ** for the address.

•To address a single cube, use the specific ID of that cube, such as A6 or 00 or 1B.

•To address all the cubes with a certain Group ID, use an address like 3* with will address all the cubes with the Group ID of 3, but with any Unit ID. If you have three walls, and all the cubes in one of the walls have Group ID 3, this type of command would address only this wall.

Baud rate

Each cube’s baud rate must be set to the computer or controller’s baud rate. The baud rate is not auto- matically established, as it is in modems.

Terminating the series

If the serial string is very long, you may have to terminate the last cube in the string for good commu- nication. Check the Terminate RS485 box.

In most instances, this is not necessary. Terminat- ing the string unnecessarily can cause its own com- munication problems. The guide line is: If it works without terminating, leave it alone.

ASCII settings
