Once enabled, it is possible to control the digital output simply sending the SMS "CLOSEP<cellular phone interface password>" to close the digital output contact, and "OPENP<cellular phone interface password>" to open the digital output contact. If the digital output control is enabled, when an information will be requested to HI504903, an SMS with the digital output status will be sent.

HI504903 can send two types of message: alarm SMSs (upon an alarm condition at least in one of the instruments connected to the interface) and information SMS (upon specific request from the user). To use the SMS feature, a SIM card able to make a voice call must be used. Note ALARM SMSs Alarm messages are submitted by HI504903 to the cellular phone number(s) when an error occurred on one of the instruments connected to the interface. A message about an alarm condition in one instrument will be sent by the interface only if the alarm is active and the specific alarm notification was enabled during last configuration, by checking the proper box on the "message option" window of the selected device (see "Interface configuration" section). If an alarm is active in one instrument connected to the interface but its notification was not enabled during last configuration, then no SMS will be sent (however HI504903 gives indication to the user about the error condition by turning on the red LED for the RS485 port or digital input port where the instrument is connected). Note An alarm SMS can be sent only if SMS sending is user enabled through digital input terminal (#9 on page 8), otherwise no SMS will be issued. Alarm SMSs for HI142 dataloggers The format of alarm messages for HI142 dataloggers connected to the RS485 port will be: "HI142-SN<DEVICE SERIAL NUMBER>; LotlD<USER LOT ID>; Alarms: <ALARM SPECIFIC TO THE INSTRUMENT>; Rem msg: <NUMBER OF REMAINING MESSAGES>" During alarm condition, the field <ALARM SPECIFIC TO THE INSTRUMENT> on the alarm message contains the list of only active alarms (see further on for the complete list of selectable alarms). The <DEVICE SERIAL NUMBER> label is a 6-character text string with the serial number of the HI142 generating the alarm SMS. The <USER LOT ID> label is a label (up to 16 characters) with the user-defined lot identification: this is the identification lot 32 Note string that user can specify in HI92140 software before starting logging with HI142 (see "LotID" field in HI92140 software). The <NUMBER OF REMAINING MESSAGES> is a value (max. 4 digits) indicating the number of remaining messages in the SIM card (see "Interface configuration" section). The complete list of all available alarm indications (and their coded notations) for HI142 temperature datalogger is: · "Temperature": the temperature on HI142 logger exceeds low or high temperature limits. · "Low battery": the charge level of the logger battery is low and should be replaced soon; contact the nearest Hanna Service Center.
