I am using a FXT009 modem which I plan to use as the system master. I need to collect data two times a day at a remote installation and all data is to be collected via the RS232 port. As it is remote, the system will be powered by solar panels and battery, therefore I need to reduce the power usage of the modem to a minimum between times. I plan no extension cards, etc to the modem and want to use it just as it is. I need to have it do some type of a sleep and wake up using the RTC.
I had hoped to use the alarm mode, but find that is not available for the modem. What is the best I can do using my configuration.
Thanks in advance for help.
