7.2 RS-232 CONTROL

The AP445-401has many advanced remote control capabilities, which are accessible through standard RS-232 communication. The actual controlling can be accomplished through a computer control system or any other device capable of sending RS-232 commands.

7.2.1 RS-232 INTERFACE

The RS-232 commands, for the AP445-401, are in a simple ASCII character format.

1. Square brackets “[ ]” are part of the command.

2.Use uppercase letters for all commands.

After processing a command, an [OK] or [ERR] will be returned as feedback if "F" is included at the end of a command string.

Commands ending in "S" will be saved into memory. Commands not ending in "S" will still be executed but will not be restored when the system is reset or powered off then on.

7.3 DESCRIPTION OF COMMANDS

The default unit ID is zero, but may be set to a value from 0 to 99. In single unit operation, commands may be sent without the unit identifier. Unit ID 0 should be used for single unit operation.

If multiple AP445-401’s are connected to the same communication port, the units may be controlled two ways. In order to control all the units the same, commands may be sent without the unit identifier. Commands sent without the unit identifier will be executed by all

AP445-401’s.

Individual control is accomplished by first assigning each unit a unique ID number. Then each unit may be controlled individually by including the unit identifier at the end of each command string.
