Introduction
How many times have you, our your trunking customer said: "I've got one of my people wasting my radio time by playing the FM stereo and I don't know who it is". EzID answers that question. EzID comes in two versions: The standard EzID and the EzIDxl (for extended logging). The difference is the standard version has the LCD display and the xl does not have a LCD display. The xl model is designed to operate with GenWatch and it must operate with GenWatch. The standard version can operate in a stand alone mode with its display telling you which unit is calling. We have seen some very creative uses for the combination of EzID or, EzIDxl and GenWatch. One of our customers uses it to monitor his system to be notified instantly if the control channel goes down. Another customer uses it to alarm when Emergency Calls are made. Another uses it to send information back to a common point for 'follow me telephone roaming'. The following information will be primarily describing the standard version.
EzID Feature Overview
EzID is a hardware device that sits near a trunk system user's control station. Its purpose is to visually show the ID of a unit that is calling into the control station. EzID has an illuminated liquid crystal display that shows: the Type of system (Type-I, Type-II or Hybrid), Fleet or Group ID, subfleet of the unit calling in and the unit ID of the radio talking. The EzIDxl has no display and acts only as a decoder box that must be used with GenWatch. The Motorola control channel, by design, will not let EzID show a unit that "coat-tails" on the end of a conversation started by another unit. Any units talking on the same fleet, but on a subfleet different from 01, will appear on the lower right portion of the EzID display (Type-I only).
It attaches to the control station with 3 wires. An internal modification needs to be made to the control station. This modification adds one internal wire to the circuit board and takes a technician less than 1 hour. We provide schematics for the compatible radios listed below. EzID is powered from the 12V DC supply that operates the control station. The EzID box measures 5"W x 2½"H x 5¼"D. There are two connectors on the rear of the box. One is the 3 pin data and power input from the control station radio. The second connector is an RS-232 connector that sends the incoming information to other software such as GenWatch for logging purposes. A "null modem" cable is required. EzID can operate without any additional software.
EzID is created and manufactured by CTECH Logging Systems of Bakersfield, California. It is being marketed worldwide by The Genesis Group.
Brief Overview of Features
- EzID will display the subfleet and ID of the unit that is talking on the lower left side of the LCD for a Type-I fleet and only the individual ID for a Type-II system. That ID will remain on the display until another ID comes or until the EzID is turned off. If any other units in this fleet or group are talking on another subfleet, those IDs will display in the lower right side of the LCD display if this is a Type-I fleet.
- Operates by using a trunked radio's circuitry to listen to a system's control channel.
- Feeds the control channel data to the EzID through a short three conductor wire.
EzID, in technical terms, looks at the control channel's OSW (outbound signal word). When a unit initiates conversation, that unit's ID is sent over the control channel. EzID decodes and displays that ID.
- EzIDxl performs fewer computation functions internally and converts selected data to an RS232 stream that is then sent to GenWatch for analysis and reporting.
Compatibility
- Systems: Type-I, Type-II, Hybrid, Simulcast, AMSS, and in some cases SmartZone.
- Bands: 800 MHz, 900 MHz and other band trunking.
- Radios: Maxtrac, MCS2000, SyntorX, Spectra non-Astro (The Specta Astro has no location in the radio where the control channel data can be isolated. As an alternative, an MCS2000 can be used).
Operating System Requirements
EzID is an add-on device. The customer must provide the control station to which the EzID attaches. The installing technician should also know the items listed below.
Installation
"Things To Know" Checklist:
- Fleet ID of the end user or Group ID for Type-II.
- Size code of that fleet (Type-I).
- Is the trunk system Type-I, Type-II or Hybrid?
- General model name of control station radio. All of these items are set inside the EzID at installation time by DIP switch selection. These are not needed for EzIDxl since GenWatch covers these questions.
