Section 7: Remote Control Interface
7.0 Overview
A system which includes an SSPA can be managed from a remote computer over a
variety of remote control interfaces (see
Figure 7-1
).
The parallel port on the SSPA unit provides a simple form of remote control. There are
10 form C relay contacts for remote monitoring. There are 6 opto-isolated inputs for
remote control commands. To enable the remote parallel interface simply select
remote on the front panel “Local/Remote” button. When in Remote mode all front panel
commands are disabled with the exception of the “Local/Remote” button. See
Section
7.1
for details.
The serial interface supports both RS232 and RS485 standards. The control protocol
supports two formats: the Normal serial protocol (as detailed in
Section 7.2
); and an
ASCII based protocol suitable for HyperTerminal applications (see
Section 7.5
).
The Ethernet interface provides the ability to control the system through: IPNet
interface (UDP encapsulated Normal serial protocol –
Section 7.6.1
); SNMP V1
(
Section 7.6.2
) or HTTP Web interface (
Section 7.6.1.3
).
