Page 4 of 16 Introduction Nomenclature ETM9900 incorporates the Siemens HC25 engine and is intended for use within Australia, NZ and worldwide. The ETM9900J variant incorporates the Siemens HC28 engine and is intended for use within Japan on the Softbank network and global roaming. Overview.
Page 5 of 16 Power Supply The ETM9900(J) power connection is a 6 pin RJ12 connector, pin allocations are shown below. Function Power Supply (+6 to +35VDC) Not Used Not Used Not Used Not Used RJ45 I/O Connector 4 x I/O’s configurable as digital, analogue or pulse are available on the RJ45 connector, pin allocations are as shown below.
Page 6 of 16 Serial (RS232) Port The RS232 Port is the primary interface for the application software and connection to external devices. AT commands are used to communicate with the terminal. The RS232 interface is implemented as a 9-pin D-Sub socket with screw fittings. Function DCD Out RXD Out...

Page 13 of 16 2. Set I/O1 as Digital Low to High (NC), the message Tank Level Low will be sent to each phone number when I/O1 changes from closed to open circuit Note: 1. Delay before alarm is activated is recommended to reduce the incidence of multiple SMS being sent in the event of chattering/bouncing contacts 2.
Page 14 of 16 Temperature Alarm I/O 3 and 4 can be used as analogue 0-2.5V analogue inputs, which can be used in numerous applications including; ◩ Temperature monitoring of a cool room or PC/Server room ◩ Monitoring tank, or stream levels using a level transmitter Example Monitor a server room, SMS based on temperature rise and/or fault alarm from A/C unit.
Page 15 of 16 Set I/O1 as Digital High to Low (NO), the message A/C Unit Fault will be sent to each phone number when I/O1 changes from open to closed circuit Set I/O3 as Analogue, in this case 4mA represents -40 C which corresponds to 500mV and 20mA represents 85 C which corresponds to 2500mV therefore 1500mV trip point equates...
