Parameter 266 defines which protocol is used for communication via the second COM2 port of the
device. COM2 is accessible in the form of the RS232 port at X4 (25-pin SubD female connector). The
option card (modem, RS485) is also connected via COM2. The signals for X4 or the option cards are
connected together in circuit in the inverter. This means that it is not possible to use different protocols
via the second RS232 and the option cards.
The following settings are possible:
Value Meaning
0
ASCII protocol (for using the inverter with HyperTerminal)
1
Solutronic protocol (for using the inverter with SOLPLUS+). N.B.: Leave parameter 266
set to the value 0; 0 = ASCII protocol is automatically switched internally to 1 =
Solutronic protocol
2
Debug function. Do not use.
3
Modem with ASCII protocol
4
Modem with Solutronic protocol. N.B.: When operating via modem, leave parameter 266
set to the value 3; 3 = Modem with ASCII protocol is automatically switched internally to
4 = Modem with Solutronic protocol
5
Large RiCo display
6
Large Schneider display
7
GSM modem with ASCII protocol
8
Not active
9
SolarLog protocol for SolarLog™ data logger
Note
SolarLog™ and Solutronic's master-slave data communication function
can not be used at the same time.
N.B.: If you want to operate the inverter directly and locally using a PC, please use the 0 setting
(default setting).
In this case, it is unimportant whether you use RS232 or RS485 to establish a link with the inverter or
the inverter's data network.
Automatic switch-over of the type of protocol from 0 to 1 (i.e. from operation with HyperTerminal to
operation with SOLPLUS+) cannot be reversed. To do so, the inverter would have to be reset, i.e.
switched off and on again. The same applies to automatic "switch-over" of the type of protocol from 3
to 4 (i.e. from modem operation with HyperTerminal to modem operation with SOLPLUS+).
If the protocol setting is 3, 4, 5 or 6, this port cannot be used directly with HyperTerminal or
SOLPLUS+. To do so, the corresponding parameter has to be reset either by means of the display or
via the other port.
