7.0 Overview
A system, which includes a RCP2, can be managed from a remote computer over a
variety of remote control interfaces (see Figure 7-1).
The parallel port on the RCP unit provides a simple form of remote control. There are
10 form C relay contacts for remote monitoring. There are six 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 RS-232 and RS-485 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 7.6.2); SNMP V1
(Section 7.6.3) or HTTP Web interface (Section 7.6.4).
