specific address of the remote host will lock RCP2 access to this host. Packets
received from other hosts will be ignored. For other parameters (IP address, Gateway,
Subnet, IP port) contact your network system administrator.
Important! If you are planning to access the RCP2 through the Internet,
you must exercise the appropriate security measures. It is strongly
recommended to put RCP2 units behind a protective Firewall or set up a
VPN link for remote access.
After selecting the IP parameters, you may turn on IP interfaces through front panel:
“Main Menu” → “2.Com.Setup” → “4.Interface” → “3.IPNet” (Enter).
Ethernet Interface is now the primary remote control interface and the RS232/485 Main
port is disabled. You may adjust any IP settings when the IPNet interface is turned on
as needed without losing your IP link. All new settings will become effective only after a
RCP2 controller hardware reset (“Main Menu” → “5.Options” → “6.Reset” or cycle
power to the unit). To disable the Ethernet port and enable the RS232/485 port:
“Main Menu” → “2.Com.Setup” → “4.Interface” → “1.RS232” (Enter).
-OR- “Main Menu” → “2.Com.Setup” → “4.Interface” → “2.RS485” (Enter).
Important! At present, the RCP2 controller supports one remote control
protocol selection through its Ethernet interface port. This protocol is
referred to as "Normal" on the front panel display (See Section 3.3.2.1). If
the protocol selection is set to “Terminal”, the controller will force its
protocol selection to "Normal".
The RCP2 Ethernet port can be connected to a network hub through straight through
network cable or directly to a work station NIC card through a null-modem or cross-
over cable (Rx and Tx lines are crossed). As soon as an Ethernet interface has been
