THE STROBECOM II SYSTEM IS DESIGNED TO AID IN THE TRANSIT OF DESIGNATED VEHICLES THROUGH
THE TRAFFIC CONTROL SYSTEM, TO THEIR DESTINATIONS.
IT IS IMPERATIVE THAT THE DRIVERS OF EACH TYPE OF VEHICLE THAT USES THE STROBECOM II
SYSTEM BE MADE AWARE OF THE RESPONSE HE CAN EXPECT FROM THE TRAFFIC CONTROL SYSTEM.
IT IS THE RESPONSIBILITY OF THE CUSTOMER TO CONFIGURE THE SYSTEM’S RESPONSE TO EACH
VEHICLE TYPE AND TO EDUCATE EACH DRIVER TO EXPECT THE APPROPRIATE RESPONSE FROM THE
SYSTEM.
AT NO TIME SHOULD A DRIVER OF A VEHICLE EXPECT THAT HE IS GUARANTEED TO RECEIVE
PROTECTED RIGHT-OF-WAY THROUGH TRAFFIC INTERSECTIONS. DRIVERS OF VEHICLES THAT WILL

Strobecom II 4140 and OSPOC
Front panel guide
The front panel of the Strobecom 4140 and OSPOC provide the user with feedback on the system status
as well as Ethernet communications. A single pushbutton on the front panel is also provided to select
actions specific to on-site installation and verification operations. The user may enable or disable
channels, enable or disable transit on channels, test channels using either transit or emergency band,
and activate the ranging process. The user may also reset the system to the default configuration. A
timeout is provided such that after 30 seconds of inactivity, the menu idles.
1Front Panel Overview
1.1 Components
1.1.1 On Indicator LED
This LED provides information on the health of the system. When the system is powered, this LED will
pulse at a 2 second rate, called a heartbeat. Upon a power-up, a red heartbeat is used to indicate the
system is initializing. Once initialized, a green heartbeat will appear. The green heartbeat indicates the
system is operating normally.
Note: The heartbeat indicator LED is labeled as ‘on’.
1.1.2 Power Switch
The power switch is used to turn power on or off to the Strobecom II 4140 and OSPOC.
1.1.3 Ethernet Connector
The RJ45 Ethernet connector provides Ethernet connectivity to the Strobecom II 4140 and OSPOC.
1.1.4 Channel LED Display
These LEDs are numbered 1 to 6, indicating the respective channel for preemption. Under normal
operations these LEDs indicate the status of any preemption events. These LEDs are also used in a menu
system for access to the commands available from the front panel.
1.1.5 Select Pushbutton
The pushbutton is used to access the front panel command menus.

Front Panel User Guide Page 5
1.2 Front Panel Command Menu Selection
Two command menus are available via the front panel. A simple menu provides only emergency band
test functions for the channels. The full command menu can be selected to gain access to the full array
of system commands.
By default, the simple command menu is enabled. In order to select the full command menu, navigate
to channel 6 LED and depress the pushbutton for at least 5 seconds. This same process is used to toggle
between the simple and full command menus.
Note: While utilizing the pushbutton with the full command menu enabled, the LED on channel 6 will
slowly flash amber –indicating that the full command menu is enabled. It only flashes during
pushbutton activity –not when idle within the full menu.
Note: In the event that all front panel LED indicators are solid red (a configuration corruption has been
detected), the full menu system is enabled. This allows the user to press and hold the pushbutton to
reset the system to defaults (an operation that is only accessible via the full command menu).
1.3 Front Panel Simple Command Menu
The simple command menu offers only the emergency band test command. The pushbutton is used to
select the channel for the test and then held for a short duration of at least 2 seconds to execute the
test on the selected channel.
Note: Upon a power-up event, the simple command menu is enabled by default.

Front Panel User Guide Page 6
1.4 Front Panel Full Command Menu
The full menu is comprised of three levels. The first level provides selection of a command group. The
second level comprises command sets within that group. The lower level is the activation of the
command on a specific channel or channels. Menu navigation and currently selected items are
depicted using the front panel LED display. In the figure below, the active LED locations that are utilized
at the top level of the menu navigation are shown in green. The pushbutton is used to navigate the
menu system.

Note: During active preemption, the front panel menu system is overridden. The user should not use
the front panel pushbutton during preemption events.

Front Panel User Guide Page 7
There are 3 typical pushbutton operations. A selection press, a utilize press, and an activation press.
1. Selection press –This is a press of the button and release within 2 seconds. It is used to
navigate the current level of the menu and to select a channel. Upon release, the next menu
item will be selected and indicated using the front panel LED display.
2. Utilize press –This is a press of the button that is held for more than 2 seconds, but less than 4
seconds. It is used to enter the sub-menu or select a command to use. Upon expiration of the
two second interval, the LED may change according to the current state. When entering a sub-
menu, the LED will change to amber. When selecting a command to use, the LED display may
vary depending upon the command type (see Commands Illustrated section).
3. Activation press –This is a press of the button that is held for more than 4 seconds. It is used to
activate a command on the chosen channel. Upon expiration of the 4 second interval, the LED
will change per the command selected (see Commands Illustrated section).
Note: The channel 5 LED is visible for navigational purposes. However, there is no functionality for this
menu item. Channel 3 and 4 LEDs are not used at the top level, but are used for submenu items.
Note: Log entries are created when enabling or disabling a channel and tests for either band, except on
channels 5 and 6
Note: When inside a submenu, selection presses will cycle through the submenu items only once. After
the last submenu item is selected, the next selection press will navigate up in the menu –back to the top
level menu item related to submenu just visited.
Note: During the selection of a channel for activation (after a command has been selected), selection
presses will cycle through the channels. An option to select all channels is available for some commands.
The only method to exit this mode is to wait for the pushbutton inactivity timeout to place the menu back
to the idle state. This timeout is 30 seconds.
Note: Submenu items are displayed starting with the LED position inherited from the top level menu
item. As an example, when entering the ranging and test submenu the first submenu item is displayed
on the channel 2 LED –the same channel LED as the top level menu item.

Front Panel User Guide Page 8
2Full Command Menu –Commands Illustrated
The process of activating each command is shown in this section. In these illustrations, it is assumed
that the menu system begins in the idle state. If the state of the menu is not certain, the user may wait
30 seconds to ensure the menu has exited to the default idle state.
2.1 Enable/Disable Menu: Channel Enable or Disable
A channel disable operation will disable preemption outputs for a channel. Preemption events will be
tracked and logged as configured, but no preemption output is allowed if the channel has been disabled.
Note: Disabled channels are indicated as a solid red LED on the front panel, regardless of the state of the
intersection. The only exception is when navigating the menu system.
1. Select the Enable/Disable menu item. Issue a
selection press on the pushbutton (< 2 s). The
front panel indicates that the top level menu
item for Enable/Disable has been selected.
2. Utilize the Enable/Disable submenu
commands. Issue a utilize press on the
pushbutton (> 2 s). Release the button after the
LED changes to amber. The front panel indicates

Enable/Disable has been selected. This is the
first submenu item which is the channel disable
item.

5.5 Determining Which Channels Have Transit Band Disabled
The front panel provides no indication of which channels may have transit band disabled. In order to
determine which, if any, channels have transit disabled the full menu must be used. The process is
similar to enabling or disabling transit for a channel with the exception being the command is not
activated. The process is simply run to the channel selection stage to determine the status. Once the
status for each channel has been determined, the user may simply wait 30 seconds to allow the menu to
reset to the idle state.
