Chapter 18 – Hardware-Related Commands 18.3 Intentionally Omitted 18.4 Intentionally Omitted 18.5 AT^SCTM Set Critical Operating Temperature Presentation Mode or Query Temperature Description: Use this command to monitor the temperature range of the module. CAUTION: During the first 15 seconds after start-up, the module operates in an automatic report mode: URCs can be always displayed regardless of the selected mode . The write command enables or disables the presentation of URCs to report critical temperature limits. The read command returns: • the URC presentation mode. • information about the current temperature range of the module. Select to enable or disable the presentation of the URCs. Please note that the setting will not be stored upon Power Down; i.e., after restart or reset, the default =0 will be restored. To benefit from the URCs =1 needs to be selected every time you reboot the GSM engine. Test Command Syntax: AT^SCTM= Response: ^SCTM:(list of supported s) OK Read Command Syntax: AT^SCTM Response: ^SCTM: , OK ERROR +CME ERROR Write Command Syntax: AT^SCTM= Response: OK ERROR +CME ERROR Parameter Descriptions: 0 Presentation of URCs is disabled (except for equal to -2 or +2). Default. 1 Presentation of URCs is enabled. -2 Below lowest temperature limit (causes immediate switch-off) -1 Below low temperature alert limit 0 Normal operating temperature 1 Above upper temperature alert limit 2 Above uppermost temperature limit (causes immediate switch-off) Notes: • Please refer to the “Hardware Interface Description” for specifications on critical temperature ranges. • To avoid damage the module will shut down once the critical temperature is exceeded. The procedure is equivalent to the power-down initiated with AT^SMSO. • URCs indicating the alert level “1” or “-1” are intended to enable the user to take appropriate precautions, such as protect the module from exposure to extreme conditions, or save or back up data etc. The presentation of “1” or “-1” URCs depends on the settings selected with the write command: If =0: Presentation is enabled for 15 s time after the module was switched on. After 15 s operation, the presentation will be disabled; i.e., no URCs will be generated. If = 1: Presentation of “1” or “-1” URCs is always enabled. • Level “2” or “-2” URCs are followed by immediate shutdown. The presentation of these URCs is always enabled; i.e., they will be output even though the factory setting AT^SCTM=0 was never changed. • If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure the temperature and to deliver alert messages, but deactivates the shutdown functionality. Once the call is terminated full temperature control will be resumed. If the temperature is still out of range ME switches off immediately. Multi-Tech Systems, Inc.

Chapter 18 – Hardware-Related Commands Unsolicited Result Codes: URC 1 URCs will be automatically sent to the TA when the temperature reaches or exceeds the critical level or when it is back to normal. URC 2 ^SCTM_B: for module (board) temperature Examples: Example 1 URCs issued when the operating temperature is out of range: ^SCTM_B: 1 Caution: Engine close to overtemperature limit. ^SCTM_B: 2 Alert: Engine is above overtemperature limit and switches off. ^SCTM_B: -1 Caution: Engine close to undertemperature limit. ^SCTM_B: -2 Alert: Engine is below undertemperature limit and switches off. Example 2 URCs issued when the temperature is back to normal (URC is output once): ^SCTM_B: 0 Engine back to normal temperature. Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371B) 229
