GSM Commander GC0321 User Manual

10. MESSAGE PARAMETERS
The GSM Commander support the use of parameters in predefined messages. This allows the user to
insert and refer to certain values in message.
➢ \t – Current time (HH:MM:SS)
➢ \d – Current date (DD/MM/YYYY)
➢ \a – Current analog input reading (0-255)
➢ \# – Unit's serial number
➢ \f – Unit's current firmware version
➢ \b – Battery voltage (in volts)
➢ \p – Current power status of mains
➢ \1 – Temperature probe A reading (in °C)
➢ \2 – Temperature probe B reading (in °C)
➢ \s – GSM signal strength (in %)
➢ \c – Airtime credit remaining (local currency)
➢ \i– Current status of inputs (32-bit hexadecimal bitmap)
➢ \o – Current status of outputs (32-bit hexadecimal bitmap)
➢ \v – Last received voice call number
➢ \w – Last received voice call name
➢ \m – Last received message number
➢ \y- Last received message name
➢ \q – Last received message text
➢ \@ - Last scanned RFID tag
➢ \! - Last scanned RFID tag name
➢ \r – Carriage Return (0x0D)
➢ \n – Line Feed (0x0A)
➢ \$ - Asset ID
➢ \+ - Own number
➢ \A – Variable A
➢ \B – Variable B
➢ \C – Variable C
➢ \D – Variable D
➢ \E – Variable E
➢ \F– Variable F
➢ \G– Variable G
➢ \H – Variable H
➢ \I – Variable I
➢ \J – Variable J
➢ \K – Variable K
➢ \L– Variable L
➢ \M – Variable M
➢ \N – Variable N
➢ \O – Variable O
➢ \P – Variable P
For example:
“Serial no \#'s signal is \s%” will send “Serial no 100641-12345's signal is 75%”
For Variables A..P, it is also possible to specify a decimal point. You do this by adding a number (1,2
or 3) after the parameter, and this number will indicate the position of the decimal point. \A1 will
show digit after the decimal, \A2 will show 2 digits etc. Let us assume Var A contains temperature,
and a value of 213 is supposed to correspond to 21.3°C, then you can specify this in a message as
follows: “Temperature in fridge is \A1 degrees”
This parameters also apply on serial / RS232 commands by using the following parameter:
*SLASHx#
x = parameter, example “s” for signal strength (without the slash “\”)
Example: *SLASHs# return the signal strength in the following format: SLASHVAR=80
Please Note: All message parameters are case sensitive.
