1. PRODUCT OVERVIEW 1.1. General Description There are several water ferry crossings in New Brunswick, under the jurisdiction of NBDOT, which require a lighted notification system for ships traveling up and down the water ways. This notification system needs to be able to notify non-ferry vessels to proceed or halt based on the condition of cable system used to move the ferries across the width of the river. The Cable System which provides the motive force for the ferries, changes in height depending on the position of the ferry and can be damaged and can also cause damage by/to non-ferry vessels as they travel up and down the water way. The Ferry Crossing Light Controller is designed to allow Ferry operators to control the signal light condition of their respective crossing from the bridge of their vessel using UHF Radio frequencies. 1.2. System Description - Theory of Operation 1.2.1 Assumptions Each Ferry to be equipped with a controller (antenna supplied by others) Each end (shore side) to a Ferry Crossing will have a control box and appropriate lighting (lighting and antenna supplied by others) Visual confirmation is all that is required for the operation of the system The Radios to be used are simplex radio's Radio & Antenna alignment are such that adjacent crossings and their respective ferries don't interfere with one another Power is supplied in the Ferry in the form of nominal +12VDC Power is supplied at each end of each crossing in the form of 120VAC 60Hz single phase Ferry Operators are responsible for selecting the correct crossing in the system. 1.2.2 Ferry-side operation Figure 1: Ferry-side Controller Front Panel Cartel Communication Systems Inc.

Each Ferry will have a Ferry-side controller installed. The Ferry-side controller front panel consists of a Crossing Selector, a Red Light button and a Green Light button. The Ferry-side controller is used to operate the Red or Green light of a selected crossing. A crossing is selected by rotating the Crossing Selector knob to the desired crossing. This adjusts the CTCSS encoder to the CTCSS tone assigned to that crossing. The operator must take care in selecting the appropriate crossing. The Green Light and Red Light push buttons generate different DTMF signaling tones, which control the shore-side units to change to the selected light colour. The embedded radio is set to operate on a fixed simplex channel (464.6625MHz) and requires an external antenna (not supplied). The Ferryside controller is housed in a heavy duty glass reinforced polyester enclosure and requires a +12V DC supply to operate. 1.2.3 Shore-side Operation Each crossing will be have two Shore-side controllers installed (one at each end presumably). The Shore-side controller consists of a NEMA-4 enclosure containing an embedded radio, CTCSS Decoder, Power Supply & DTMF Decoder. The Shore-side controllers are configured for fixed CTCSS tone. There are two Shore-side controllers per CTCSS tone (please refer to Figure 3). The controllers will only respond to signals with matching CTCSS tones. This segregates one crossing from another. After seeing a matching CTCSS tone, the DTMF signal, which is sent from the Ferry-Side controller, is decoded. The appropriate relay output is triggered depending on which DTMF string is sent. The embedded radio is set to operate on a fixed simplex channel (464.6625MHz) and requires an external antenna (not supplied). The Shoreside enclosure is housed in a heavy duty metal enclosure and requires a 120V AC to operate. 1.2.4 Potential Drawbacks There could be an issue if the operator selects the improper crossing and then transmits a light change signal. He may not have visual confirmation of the incorrectly changed crossing. Cartel Communication Systems Inc. All Rights Reserved. Page 5 of 10

2. CONFIGURATION The following is the CTCSS Assignment chart: Shore-side Name CTCSS Frequency TS64 Jumper Position Gondola Point 67.0Hz All Out Kennebecasis 71.9Hz JP6 Gagetown 196.6Hz JP5 Westfield 36.6Hz JP4 Hampstead 91.5Hz JP3 Belleisle 79.7Hz JP2 Evandale 74.4Hz JP1 2.1. TS-64 CTCSS Decoder Board (Shore Side) The TS-64 is solder bridge configured per crossing for the desired CTCSS tone. These boards have been configured for Receive Audio Mute Output to be pulled to ground by solder bridging JP7. This ensures that only a signal which is meant for a specific crossing is received. Please reference the included TS-64 User Manual for information regarding the configuration of the TS-64. 2.2. TS-64 CTCSS Decoder Board (Ferry Side) The TS-64 is wired to the 7 Position Crossing Selector. Selecting a crossing using the selector sets the desired CTCSS tone. Please reference the included TS-64 User Manual for information regarding the configuration of the TS-64. 2.3. NC-409 DTMF Encoder (Ferry Side) The NC-409 is configured to send a DTMF signal of 148 when the Green button on the front panel of the Ferry Side controller is pressed. It is configured to send a DTMF signal of 1489 when the Red button on the front panel of the Ferry side controller is pressed. The NC-409 is also set to send digits at a rate of 10 digits per second. Please reference the included NC-409 User Manual for information regarding the configuration of the NC409. Cartel Communication Systems Inc. All Rights Reserved. Page 6 of 10

2.4. NC-400 DTMF Decoder (Shore Side) The NC400 DTMF Decoder is configured to close the primary relay when it receives a DTMF signal of 148 and it will open the primary relay upon reception of a DTMF signal of 1489. Please reference the included NC400 User Manual for information regarding the configuration of the NC400 2.5. Midland SD225U2 UHF Radio (Shore and Ferry Side) The Midland SD225U2 UHF Radio is programmed to transmit on a simplex channel of 464.6625 (25kHz wide). All programming of the radio is done using the supplied software and interface cable. Please reference the included SD225U2 User Manual for information regarding the configuration of the SD225U2.
