In order to test for proper operation, you may wish to perform the following test. Note that it is not necessary to connect a device to either switched circuit in order to perform this test. a) Reboot Circuits: T o initiate a bo[...]

4. Installation 4.1. Power Connection Connect your DC power supply to the Circuit 1 Input T erminals as shown in Figure 4.1. Connect the power supply lines from your DC Powered device to the Output T erminals. Note that the RPC-4840N is available with two separate 40 amp circuits. In order for both circuits to function, power must be connected to b[...]

4.2. Option Switches The Option Switches select default settings for the Baud Rate, Command Echo, Boot Delay and Disconnect T imeout. Default settings selected via the Option Switches will be used when the unit is reset to default parameters as described in Section 4.3. Notes: • Although the Option Switches select default settings for these featu[...]

4.3. Reset Unit to Defaults If Option Switch settings are changed, the new settings will not be applied until the unit is reset to default settings. There are two ways to reset the unit to defaults: Note: When these reset procedures are performed, all user selected parameters, including passwords and circuit names will be lost. Prior to performing [...]

4.4. Console Port Connection The Console Port is a male, DB9 connector , wired in a DTE configuration (similar to an A T style computer), which is used for connection to a local PC or control device. Appendix A describes the Console Port interface. 4.5. Connecting an External Modem When connecting directly to an external modem, use a standard DB9 A[...]

5. Configuration 5.1. System Mode and User Mode In order to restrict access to sensitive command functions, the RPC-4840N features two separate operating modes; System Mode and User Mode.

5.2. Communicating with the RPC-4840N In order to configure the unit or invoke command functions, the user must first connect to the RPC-4840N and access the command mode. 1. The RPC is transparent to parity and will accept 7 or 8 bit characters, but will always answer back at 8 bits, no parity . Make certain your communication program (e.g. HyperT[...]

[...]

5.3. Command/Menu Conventions When invoking RPC-4840N commands and selecting items from configuration menus, note the following: · T o display the Help Screen, type /H [Enter] . · All RPC commands can be invoked at the RPC> command prompt, or from the General Parameters Menu, Port Parameters Menus or Network Parameters Menu. · RPC commands ar[...]

3. Modem Initialization String: T o define the Modem Initialization String (up to 32 characters), type 3 and press [Enter] . For more information on the initialization string, please refer to the user's guide for your external modem. Make certain that the modem is set to auto- answer in one ring. (Default = ATE0M0Q1&C1&D2S0=1 ). 4. Mod[...]

7. Disconnect Timeout: Determines how long the RPC will wait for additional commands. T ype 7 , press [Enter] , and follow the instructions in the submenu. (Default determined by Option Switch 4; Factory Setting = 2 Min.). Note: It is recommended that the Disconnect T imeout should be set at the lowest acceptable value. Since only one port is allow[...]

A. Default Parameters: Resets the RPC to the default values specified by the Option Switches. In addition, all menu selected parameters, including circuit names and passwords, will be lost. If Command Confirmation is disabled, the "Sure?" prompt will not be sent. Note: If the Default Parameters function is invoked via the Network Port, th[...]

2. Password: (Up to 16 Characters) Assigns a User Password to this circuit. When a User Password is assigned, the circuit is then "owned" by that password. When a User Password is entered at login, the user will have access to only the circuit(s) which are owned by this password. (Default = undefined). Notes: · If you wish to allow a sin[...]

5.6. Network Parameters In order to communicate with the RPC-4840N via network, the IP Address, Subnet Mask and Gateway Address must first be defined using the Network Parameters menu. If desired, this menu also allows you to implement IP Security features, which restrict command mode access based on the user's IP Address. Settings for network[...]

5.6.1. Implementing IP Security The RPC-4840N can be configured to restrict unauthorized IP addresses from T elneting to the unit. This allows the user to grant T elnet access to only a specific group of IP addresses, or block a particular IP address from gaining access. In the default state, the RPC accepts incoming IP connections from all hosts. [...]

Example 1: Deny access to all hosts except 192.1.1.5: Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants access to 192.1.1.5 only . Example 2: Allow access only by addresses that begin with 192. Since 255 is a wild card, Mask 1 blocks all IP addresses. Mask 2 then grants access to all addresses that begin wi[...]

5.7. Save Configuration Parameters After the unit has been completely configured, it is recommended to save parameters to an ASCII file as described in Section 7. This allows quick recovery in the event that the unit is reset to default parameters, or the configuration is accidentally deleted or altered.[...]

6. Operation 6.1. Access the Command Mode Commands can be sent to the RPC-4840N via Network or modem, or from a local PC connected to the Console Port. T o access the Command Mode, proceed as follows: Note: Only one port can access command mode at a given time. When you have finished communicating with the unit, always make certain to disconnect us[...]

6.2. Displaying circuit Status The Status Screen displays the On/Off state and selected parameters for the switched circuits. T o display the Status Screen, type /S and press [Enter] . Note that although the /S command is available in both User and System Mode, the System Status Screen includes more information than the User Status Screen. When the[...]

6.3. Boot/On/Off Commands These commands are used to Boot or toggle the On/Off status of the RPC-4840N's two switched circuits. If the same password has been applied to both circuits, commands can be directed to Circuit 1, Circuit 2, or both circuits. If a separate User Password has been assigned to each circuit, then commands can only be appl[...]
