Hello,
FM1202 has no possibility to set ignition as power voltage. For FM5300 please use setparam SMS command
Setparam SMS structure is: setparam X### #, where X is profile number (default is 3).
Ignition source parameter id is 900, values: 0 - DIN1, 1 - external voltage
High voltage level parameter id is 901
Low voltage level parameter id is 902
For example:
to set ignition source as external voltage in profile 3 send: setparam 3900 1
to set high voltage in profile 3 to 30V (30000 mV) send: setparam 3901 30000
to set low voltage in profile 3 to 13,2V (13200 mV) send: setparam 3902 13200
SMS structure is as follows: <login><space><password><space><command> or if you don't have sms login and password set, leave two spaces in front of the message
To check in which profile device is currently working send getinfo SMS command, Answer Example: INI:2007/8/24 10:15 RTC:2007/8/24 12:43 RST:2 ERR:11 SR:182 BR:0 CF:0 FG:0 FL:0 UT: P:1;0;1;0;0;0 SMS:2 NOGPS:0:0 GPS:3 SAT:7 RS:7 RF:11
P:1 -means that current profile is 1
example of setparam message where sms login is admin and password is opa: "admin opa setparam 3900 1"
example of message where there is no sms login and password set: " setparam 3900 1"
Best regards
