Connecting the modem to the Sunny Boy Control
Connect the serial port of the modem (V24/RS232C) with the “PC (COM2)” port of
the Sunny Boy Control using an RS232 cable.
Use the RS232 cable supplied with the modem, not the null modem ca-
ble supplied with the Sunny Boy Control (this one is used to connect to a
PC).
With the PC connection cable used for data acquisition, the signals inside
the cable are crossed. With the RS232 cable used for connecting the
modem (also called “V24 cable”), however, the signals are "one to
one". Since these cables look alike, be sure not to confuse them.
Connecting the modem to the phone and power lines
Make all necessary modem connections according to the maker’s instructions. This
typically consists in plugging the power adapter into an electrical outlet and plugging
a phone line into the line jack on the modem and into a phone jack on the wall.
Modem detection by the Sunny Boy Control
Switch on the modem and the Sunny Boy Control. After approximately one minute,
the Sunny Boy Control should automatically detect the modem connected to the “PC
(COM2)” connector. Otherwise, check the modem’s power and phone connections,
and then turn the Sunny Boy Control on again (the automatic modem detection takes
place only at power-up).
Any fax class 2 or 2.0 modem should support the default settings. Otherwise, the
modem init (or initialization) string can be adjusted. See section 6.6.1 for details.
