Configuration Messages
The following messages are sent to the TrimTrac 1.5 to configure application,
GPS and GSM parameters and to set Vehicle Adapter or Control Module alert and
application parameters.
SET_ALERT_STATE
This message is sent to the TrimTrac 1.5 to acknowledge or clear alert states;
provided, however, that the TrimTrac 1.5 is connected to a Vehicle Adapter or
Control Module. When received the TrimTrac 1.5 will send a
RESP_ALERT_STATE message in response, UNLESS:
1. the SET_ALERT_STATE messages attempts to Clear an alert before all
activated inputs have been returned to their normal non-alert conditions, in
which case, no RESP_ALERT_STATE message will be sent. Instead, a
new alert message will be generated.
2. If battery powered, sending the device a SET_ALERT_STATE message
will have no effect and not cause a RESP_ALERT_STATE message to be
returned.

Table 49, SET_ALERT_STATE Message
Sample SET_ALERT_STATE Message to ACKNOWLEDGE alerts:
>STKL333;PW=00000000;ID=00000000;*16<
Sample SET_ALERT_STATE Message to CLEAR all alerts:
>STKL000;PW=00000000;ID=00000000;*15<
NOTE: Sending a Clear command before returning all conditions to their normal, non-
alert states will re-initiate the alert message sequence. If you wish to silence an activated
alert before the monitored device or condition have been restored to their normal non-
alert state, then send an acknowledgement SET_ALERT_STATE message. This will not
clear the alert, but it will stop re-transmissions until the condition is cleared.
