Communication ports
The relay has three communication ports as standard. A fourth
port, Ethernet, is available as option. See Figure 6.1-1.
There are three communication ports in the rear panel. The
Ethernet port is optional. The X4 connector includes two ports:
local port and extension port. The front panel RS-232 port will
shut off the local port on the rear panel when a VX003 cable is
inserted.
Figure 6.1-1. Communication ports and connectors. By default the X5 is a
D9S type connector with TTL interface. The DSR signal from the front panel
port selects the active connector for the RS232 local port.
By default the remote port has a TTL interface. It can only be
used together with external converters or converting cables.
Inbuilt options for RS-485, fibre optic (plastic/plastic,
plastic/glass, glass/plastic or glass/glass), Profibus and
Ethernet are available.
