Hi
i wonder if any one can help me to know the minimum signal stringth & power needed to send a SMS message if u can support your answer by a document.
thank you so much

Deep sea technical support reply but it is disappointed :-( : Deep sea technical support :You can use any modem for the PC side, we recommend the Multitech Global Modem ZBA or the Wavecom Fastrak as we know them to work well.
The SIM card in the GSM modem must support CSD (Circuit Switched Data)...
Hi
i need to monitor and control the generator by PC via GSM
(i choose the gsm bcoz the genset in the desert, away 100 km from the control room) the generator's control module is DSE7510, i have also GSM modem (Wavecom fastrack M1306B) and pc software for monitoring. my inquiry is do i need...
Hi all
i has 3 phase wye connection 400V LL, 230V LN, 30KVA
i wanna make it single phase i read in the generator manual the best way to make it single phase is the double delta. my question is: when i make the connection double delta does this decrease the rating power
? or the generator will...
actually the terberg "synch. module" phase voltages was L1=0,L2=680,L3=400 but i measured it by voltmeter: L1L2=400,L2L3=400,L1L3=400 .... and according to ground
L1=0,L2=400,L3=400 !!! does any one tell me y this transformer act like that ??!!
i tested it according to the ground and according to the other phase even i touch it by bare hand and bare feet !!! it's voltage 0 zero... that's really make me sick :(
we faced a problem in power plant consisted of 4 diesel generators 400 v synchronise togather and every generator connected to 400v/11kv delta/wye Transformer the synchronisation in low voltage side (400v) when we turn on the first generator it's transformer rise up the voltage to 11kv and this...
