1. Introduction
Network equipment sometimes "locks-up", making it impossible
to communicate. The RPB+ Remote Power Boot Switch can
switch AC power on 5 individually controlled plugs, allowing
attached equipment to reset (re-boot).
ASCII commands are sent to the RS-232 Control Port to select
plugs, and specify On, Off, or Boot operations. A convenient
Status Screen shows On/Off conditions at each plug. RPB+
features include a security password, Location I.D. field, and
plug labels to identify the device connected to each plug.
Features:
Remotely Toggles AC Power to Five Separate Outlets.
·
Serial RS232 Control Port Interfaces Directly with a PC or
·
External Modem, Allowing Local or Remote Control.
Status Display Shows Plug Labels and On/Off Conditions.
·

3. Installation
3.1. SetUp Switches
The SetUp Switches select the baud rate and Off Time, and
enable/disable the Password feature and Read Only Mode. If
switch settings are changed while the unit is powered On, press
the Default Button to re-read switches. The Default Button
allows the user to change switch settings while power is on,
without re-booting the RPB+ and connected devices.
Note: If Rate Switch settings are changed while the
unit is powered on, new parameters will not take
effect until the Default Button is pressed, or the
RPB+ is powered Off and On.
Off Time: When a boot cycle is initiated, the "Off Time"
determines the length of time the device will remain off until
power is restored.
Password: When enabled, a password is required in order to
access the RPB+ Command Mode (Default = [Enter]). To redefine the Password, refer to Section 4.
Read Only Mode: When enabled, the /P command (Define
Parameters) is suppressed. This allows the user to invoke
On/Off/Boot commands, but prevents redefinition of
parameters such as the Password and Power-Up Default.

3.2. Control Port Connection
The male, DB9 connector (labeled "RS232") is used for
connection to an external modem or local PC. The RS232 Port
uses a DTE configuration, similar to an AT computer. Figure 3
describes the Control Port interface.

3.2.1. Connecting to a Modem
When connecting directly to an external modem, use a standard
AT to Modem cable. Make certain the modem is initialized at
the same baud rate as the RPB+ (SetUp Switch 1). The modem
must be placed in Auto-Answer mode, and set to answer in one
ring. Please refer to the user’s guide for your external modem in
order to determine the appropriate AT command string.
3.3. Power Connection
The Power Switch located on the back panel must be “On” in
order for the RPB+ to operate. Each time the unit is powered
On, the five AC outlets will be switched On or Off, as dictated
by the Power-Up Default String (see Section 4.1). Each outlet is
capable of switching up to 15 Amps of AC power. The total for
all 5 outlets cannot exceed 15 Amps.

transparent to parity and will accept 7 or 8 bit characters,
but will always answer back at 8 bits, no parity. Make
certain your communications program (e.g. ProComm) is
set for the appropriate baud rate, bits, and parity. It is also
recommended to set the communications program for TTY
mode.
a) Via Modem: Start your communications program.
Dial the external modem connected to the RPB+. Wait
for the Connect message and proceed to Step 2.
b) Via Local PC: Start your communications program.
2. Password: If the Password function is enabled, the unit
will display a prompt. Key in the Password and press
[Enter]. If the password has not yet been defined, just
press [Enter].

RPB+ User's Guide
4.1. The Power-Up Default String
The Power-Up Default String allows the user to select default
On/Off conditions for each switched AC outlet. When the RPB+
is powered up, or when the /D command (Set Defaults) is
invoked, each outlet will be set according to the Default String.
Note:
The Power-Up Default String includes five
·
characters; each character determines the default
On/Off condition for the corresponding plug. The
first character applies to Plug 1, the second
character applies to Plug 2, and etc..
To set a plug to default "ON" enter a one (1); to set
·
a plug to default "OFF", enter a zero (0).
If the Default String includes invalid or missing
·
characters, plugs will be switched “Off” when the
unit is powered up, regardless of the conditions
shown by the Status Screen. In addition, the /D
command will not function.
Example 1: To set default On/Off conditions as follows:
ON: Plugs 1 and 5
OFF: Plugs 2, 3, and 4
The Power-Up Default String would be defined as "10001".
Example 2: To set default plug conditions as follows:
ON: Plugs 3, 4, and 5
OFF: Plugs 1 and 2
The Power-Up Default String would be defined as "00111".
