Remote communication
The remote communication use optical fibres for transfer of data within a
station. For this purpose, a fibre optic bus input can be available on the
rear of the terminal, one for LON communication, and one for SPA com-
munication. The principle of two independent communication ports is
used.
When communicating locally with a PC in the station, using the rear SPA
port, the only hardware needed for a station monitoring system is:
• Optical fibres
• Opto/electrical converter
• PC
When communicating remotely with a PC using the rear SPA port, the
same hardware is needed plus telephone modems.
The software needed in the PC, either local or remote, is:
• SMS-BASE (Ver 2.0 or higher)
• SM/REx 5xx for the terminal in question
• RECOM (Ver 1.3 or higher) if disturbance recorder data is trans-
ferred to a PC
• REVAL (Ver 1.1 or higher) for evaluation of this disturbance
recorder data
When communicating to a front-connected PC, the only hardware
required is the special front-connection cable. The software needed in a
front connected PC is:
• SMS-BASE (Ver 2.0 or higher)
• SM/REx 5xx for the current terminal. The SM/REx 5xx includes one
small part of RECOM, which lets you collect disturbance recorder
data via the front port.
• REVAL (Ver 1.1 or higher) is also required if the same PC is used
for evaluation of the disturbance recorder data.
The hardware needed for applying LON communication depends on the
application, but one very central unit needed is the LON Star Coupler and
optic fibres connecting the star coupler to the terminals.
