ClimaCheck GSM Modem Manual – 2015-02-26 8(22)
despite being setup on the Modem/PPP tab. To restore connectivity over GPRS-modem
set the Gateway to 0.0.0.0
When Gateway is enabled (set to something other than 0.0.0.0), you can in many cases
only connect to the PA Pro with a direct cable connection while not being connected to
any other networks. It will not work connecting via a router or while simultaneously
being connected to a wireless network. In this case to restore the standard connectivity
you need to disable Gateway by setting it to 0.0.0.0, clicking Update and Restart.

Connecting and starting the modem
You should make all the required setting changes before starting the modem. When ready to
connecting it follow these steps:
Make sure your SIM card do not have a PIN code locking it.
Insert the SIM card in the modem. Eject holder by pushing the small round button with a
pointy object like a pencil or small screw driver.
Connect the antenna to the modem and the modem to the PA Pro using a serial cable.
Turn off the PA Pro.
Turn on the modem by connecting it to the mains.
Wait 30 seconds for the modem to go trough its start sequence. It should now display a
short blink every three seconds.
Turn on the PA Pro and wait for it to start as normal.
PA Pro and the modem should now be ready. If connected by GPRS you will see double
blinks and a longer steady blink when it is sending, but if the time between samples is long
they can be hard to spot. If the modem is waiting for a call there will only be single blinks.

Changing the Database Sample Interval
When using your PA Pro connected directly to a laptop five seconds between each sampling of data
is the standard value. When connecting by GPRS the sample rate is set in the logger and usually to
a lower value not to cause an unnecessary high data traffic cost. The settings for the internal
logger and data transfer are independent.
Read section 3.1 and 3.3 to learn how to connect to the PA Pro and change the sampling interval.
The set-up of modem configuration includes interaction of several different systems requiring a
systematic approach to set-up and trouble shooting.
The ClimaCheck PA Pro will initiate modem first time it has data to send - default 5 minutes if no
compressor power is measured – 1 minute if power is measured - this time can be shortened by
setting a shorter time in the settings (see 3.3 Changing the Database Sample Interval).
After connection of Modem to ClimaCheck PA Pro and initiating communication as described in this
manual data should be coming to the server.
