Channel switch for coupling of two redundant devices to one communication line
For protocol converters in redundant operation, maximum uptime is ensured
with the hot standby method. This means only one of the two devices is active at
any time. The passive device monitors the active one and if the active one
fails, the passive one
automatically steps in and resumes communication.
The currently active protocol converter then sends a defined signal string to
the channel switch initiating the switchover.
All communication in control and monitoring direction is then run by the second
Please note that in monitoring direction information is transmitted to both the
active and passive protocol converters, irrespective of the position of the
RS232 (V.24) 9 pin SUB-D Socket (connects to DCE) 9 pin SUB-D Plug (connects to DTE) Baudrate up to 38400 Baud CD or DSR or RI for indicating the active channel to the protocol converters
Please note that the configurator is temporarily unavailable due to maintenance reasons.
