Write
EEPROM
Value EWR= 7 bytes Command only. FACTORY USE ONLY
A command in the form ddd,aaa, where ddd is a single byte data
value between 0 and 255, and aaa is a starting address (in the
range 0 - 127) within the serial EEPROM, where the data is to
be written.
Example: EWR=127,104 means write the value 127 starting at
address location 104.
(Used for power-level cal, amongst other things)
Read
EEPROM
Value N/A 3 bytes Query only. FACTORY USE ONLY
A query in the form aaa where aaa is a starting bit address (in
the range 0 - 127) within the modem’s serial EEPROM,
requesting that the byte stored at that location be returned.
Example: ERD?063 returns the value of the byte stored at
location 063.
(Used for power-level cal, amongst other things)
Set RTC
Date DAY= 6 bytes,
numerical
Command or Query
A command in the form ddmmyy
Where: dd = day of the month, between 01 and 31
mm = month of the year, between 01 and 12
yy = year, between 97 and 96 (1997 to 2000, then 2000 to 2096)
Example: DAY=240457 would be April 24, 2057 DAY= (message ok)
DAY? (received ok,
but invalid arguments
found)
DAY* (message ok, but
not permitted in current
mode) DAY? DAY=xxxxxx
(same format as
command
arguments)
Set RTC
Time TIM= 6 bytes,
numerical
Command or Query
A command in the form hhmmss, indicating the time from
midnight
Where: hh = hours, between 00 and 23
mm = minutes, between 00 and 59
ss = seconds, between 00 and 59
Example: TIM=231259 would be 23 hours, 12 minutes and 59
seconds from midnight. TIM= (message ok)
TIM? (received ok,
but invalid arguments
found)
TIM* (message ok, but
not permitted in current
mode) TIM? TIM=xxxxxx
(same format as
command
arguments)
Set Statistics
Sample Interval SSI= 1 byte, numerical Command or Query.
Used to set the sample interval for the Statistics Logging
Function.
SSI=x, where x = 0 to 9 in 10 minute steps.
Note: Setting this parameter to 0 disables the statistics logging
function.
Example: SSI=3 means 30 minutes SSI= (message ok)
SSI? (received ok,
but invalid arguments
found)
SSI* (message ok, but
not permitted in current
mode) SSI? SSI=x (see
description for
details of
argument)
