If you wish to use more than 32 devices in line or need to bridge greater distances, make sure
repeaters (e.g. TROVIS 5482) are installed to replicate the signal. With 8-bit addressing, a
maximum of 246 devices can be addressed and connected to a bus.

Warning!

You are required to follow the relevant standards and regulations concerning lightning and
overvoltage protection on installation.

Description of communication parameters to be adjusted

Station address (ST.-NO)
This address is used to identify the controller in bus or modem mode. In a system, each control-
ler needs to be assigned a unique address.

Baud rate (BAUD)
In a bus system, baud rate refers to the transfer speed between control system and controller. In
modem mode, baud rate refers to the transfer speed between controller and modem.
The baud rate adjusted at the controller must correspond with the baud rate of the control sys-
tem, otherwise no communication can be established.

Cyclical initialization (In)
This parameter defines the period of time for a cyclical issue of the initialization command
“ATZ“. The command is not issued during dial-up or when connected. “ATZ“ causes the pro-
file 0 to be copied to the active profile, provided the modem parameters have been set and
saved in profile 0 using a suitable terminal program.

Dialing pause to the control station (PA)
It is recommendable to pause for approx. 3 to 5 minutes between dialing up to the control sys-
tem to avoid a permanent overloading of the telecommunications network. The

Dialing pause to

the control station defines the interval between 2 dialing attempts.
