3. Getting Started
This Quick Start Guide describes a simplified installation procedure for the RPC, which
will allow you to communicate with the unit in order to demonstrate basic features and
check for proper operation.
Notes:
• There are separate Hardware Installation procedures for RPC-4850 series
units and RPC-40L8A4 series units. RPC-4850 series units are discussed in
Section 3.1 and RPC-40L8A4 series units are discussed in Section 3.2.
• This Quick Start Guide does not describe unit configuration or discuss
advanced operating features in detail. For more information, please refer to
the remainder of this User’s Guide.
3.1. Hardware Installation - RPC-4850 Series Units
3.1.1. ApplyPowertotheRPC-4850
Refer to power rating nameplate on the back panel, and then connect the RPC-4850
series unit to an appropriate power source as shown in Figure 4.1.
The RPC-4850 features two separate DC inputs; connect power wires to the unit's Circuit
"A" and/or Circuit "B" terminal blocks, then connect the wires to an appropriate power
supply. Note that it is not necessary to connect power to both input circuits; either
circuit will supply power for operation and control functions. However, when power is
connected to both circuits, this allows the second circuit to function as a back-up in the
event of a power outage. The ON LED should light, and the RDY LED should begin to
flash. This indicates that the RPC-4850 is ready to receive commands.
Note that each individual output circuit will support up to 15 Amps maximum, and that
the total for all eight circuits cannot exceed 50 Amps.
3.1.2. ConnectyourPCtotheRPC-4850
The RPC-4850 can either be controlled by a local PC, that communicates with the unit
via cable, controlled via external modem, or controlled via TCP/IP network. In order to
switch circuits On/Off or select parameters, commands are issued to the RPC-4850 via
either the Network Port or Console Port. Note that it is not necessary to connect to both
the Network and Console Ports, and that the Console Port can be connected to either a
local PC or External Modem.
• NetworkPort: Connect your 10Base-T or 100Base-T network interface to the RPC-
4850 Network port.
• ConsolePort: Use the null modem cable supplied with the unit to connect your PC
COM port to the RPC-4850 Console (RS232) Port.
• ExternalModem: Use a standard AT cable or modem cable to connect your
external modem to the RPC-4850's Console (RS232) Port.
