Introduction Scope This specification defines and controls the serial communications interface between the Global Traffic Technologies

(GTT) Radio Module controller and the RF module controller through which the configuration and control of the RF module is performed. Definitions, Acronyms, and Abbreviations This section contains descriptions of terms, acronyms, and abbreviations that are used throughout this document. 3D Three dimensional RF Radio Frequency PPS Pulse Per Second Page 4 of 31 Copyright 2000-2016, Global Traffic Technologies, LLC 2. Protocol Specification The following subsections detail the structure of the protocol. Individual message types are defined in the next major section. Roles This protocol is intended to be used in a point-to-point mode only meaning one GTT controller to one RF module. The devices act as near peers in that the GTT device assumes the role of a master device in order to perform configuration of the RF module. However, once operations have begun, the RF module autonomously reports inbound data as it occurs while the GTT controller periodically sends content to be transmitted and the time index to be used in frequency hopping. Error Detection & Recovery All devices are expected to detect framing, checksum and overflow errors. If a device detects a communication error such as these, the device will not send a response to the received message. It is the senders responsibility to detect the lack of response from the receiving device and resend the command if it so chooses. During configuration, the GTT controller will perform retries to ensure that the RF module is fully configured prior to enabling over-the-air operation. If a device receives a message without error, but the message contains invalid data, or the requested operation cannot be performed due to the current context of the receiving device, then the device is expected to provide information in the response to the sender that it could not carry out the command. Under operational conditions (i.e. over-the-air), the messages are transfers of data, not diagnostics or configuration. Failure of a transfer (See annotations in the message section) shall not require a retry since loss of a single data is non-critical (i.e. either repeated or new data will be arriving momentarily). Flow Control No flow control shall be supported by this protocol. Character Format The supported binary character format is the following:

Start bits:

Data bits:

Stop bits:

1 8 1 Parity:

None Page 5 of 31 Copyright 2000-2016, Global Traffic Technologies, LLC Supported Data Types In order to specify the message formats, the following data type definitions are necessary:

Type UCHAR CHAR USHORT SHORT ULONG LONG Size 8 bits 8 bits 16 bits 16 bits 32 bits 32 bits Range 0..255

-128..127 0..65535

-32768..32767 0..4,294,967,295

-2,147,483,648..2,147,483,647 Each byte (where a byte is 8 bits in size) of these data types is serial transmitted least-significant bit first, most-

significant bit last. Multi-byte data types are transmitted least-significant byte first, most significant byte last. For example, an unsigned short with value 1234H would be transmitted as a byte with value 34H followed by a byte with value 12H (i.e. little endian). Message Format Messages are sent from the host to the radio in multiple of 8 bytes. For messages that are not even multiples of 8 bytes, the remaining package is padded with trailing zeros (0). Messages have the following structure:

<Header><Length><Command><Data><Checksum>

with the fields further defined below:

<Header>

The <Header> shall be a single UCHAR with a value 0x02 representing an STX. A message receiver begins assembling a new incoming message when it receives a <Header> meeting this specification.

<Length>

16 bit value specifying the number of bytes to follow including the checksum.

<Command>

The <Command> is composed of a single ASCII CHAR. Commands are defined in section 5. Commands that are initiated by the host are always an uppercase character. Commands that initiated by the RF module or responses to host commands are always a lowercase character.

<Data>

Page 6 of 31 Copyright 2000-2016, Global Traffic Technologies, LLC The <Data> field is an optional, variable length field which has a format that is context dependent for each

<Message ID>. The maximum length for this field is not limited by the protocol.

<Checksum>

The <Checksum> field is a single USHORT field which is the 16-bit sum (sum modulo 216) of all the bytes in the message prior to this field. This sum includes the <Header>,<Length>,<Command>, and <Data> fields. Page 7 of 31 Copyright 2000-2016, Global Traffic Technologies, LLC 3. Setup and Configuration Messages Set Mode (M) Used by the host to change the operational mode of RF module. Offline mode is an idle mode where operational setup occurs. Online mode is an active operations mode where normal transmit and receive functions are performed. Tests modes are receive test mode and transmit test mode. RF Module responds with the new active mode or a Broken Mode status. Offline Mode is characterized by no RF activity (transmitter off, receiver off) and no frequency hopping. Online Mode is possible when the RF module has been completely configured. Note: When enabled, programming mode may use a different protocol Sent by Host:

User manuals for transmitters equipped with detachable antennas shall also contain the following notice in a conspicuous location:

This radio transmitter IC 7275A-OPTICOM4 has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. This device has been designed to operate with the antenna(s) listed below, and having a maximum gain of 7 dB. Antennas not included in this list or having a gain greater than 7 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.

OEM Responsibilities to comply with FCC and Industry Canada Regulations The OPTICOMGPS4 Module has been certified for integration into products only by OEM integrators under the following conditions:

1. The antenna(s) must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times. 2. The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter. As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be Page 29 of 31 Copyright 2000-2016, Global Traffic Technologies, LLC responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and Industry Canada authorization. End Product Labeling The OPTICOMGPS4 Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC Certification Number are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following:

Contains Transmitter Module FCC ID: VJB-OPTICOMGPS4 Contains Transmitter Module IC: 7275A-OPTICOM4 or Contains FCC ID: VJB-OPTICOMGPS4 Contains IC: 7275A-OPTICOM4 The OEM of the OPTICOMGPS4 Module must only use the approved antenna(s) listed above, which have been certified with this module. The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or change RF related parameters in the user manual of the end product. To comply with FCC and Industry Canada RF radiation exposure limits for general population, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times and must not be co-located or operating in conjunction with any other antenna or transmitter.
