Command Set

4.1 Introduction

In order to avoid communication conflicts among devices trying to send data simultaneously, all the traffics are coordinated by the host computer. This action is initiated by the host computer using a command/response protocol.

When the modules are not transmitting, they are in listening mode. The host issues a command to a module with a specified address and waits for the module’s response. If there is no response, a timeout aborts the sequence and returns the control to the host.

Changing ADAM’s configuration might require the module to perform auto calibration before changes may take effect. This is the case when the range is modified especially. The module has to perform all stages of auto calibration which is also performed during the start up. When the calibration process is underway, the module does not respond to any other commands. The command set in the following pages includes the exact delays that might occur as modules are reconfigured.

4.2 Syntax

[delimiter character][address][command][data][checksum] [carriage return]

Every command begins with a delimiter character. There are four valid characters: a dollar sign $, a pound sign #, a percentage sign % and an at sign @.

The delimiter character is followed by a two-character address (hexadecimal) that specifies the target module. The actual two-character command follows by the address. Depending on the command, an optional data segment may follows by a command string. Furthermore, an optional two-character checksum may be appended to the total string. Every command is terminated by a carriage return (cr).

ALL COMMANDS SHOULD BE ISSUED IN UPPERCASE CHARACTERS!
