Introduction wireless transmission of digital data. The TS4000 can transfer data at rates up to 19,200 bits per second. The TS4000 includes a synthesized VHF, UHF or 900 MHz transceiver that can be programmed for up to 99 channels. This product is ideally suited to OEMs and system integrators who require a versatile radio modem in a single package.
Page 9
Provides easy determination of the radio coverage and signal quality between TS4000s. Available while the system is in normal operation. Can be used through Serial Port 1 or Serial Port 2 of the TS4000. Windows display software provided, free of charge, with the TS4000 Configuration Software.
TS4000 can be operated with. Transmit duty cycle is the percentage of time that the modem is transmitting (i.e. 50 %). If the TS4000 is operated with too high a transmit duty cycle, then the radio module may get too hot which can result in damage.
For the TS4000, the data rate and the type of modulation control the transmitted Transmit Channel channel bandwidth. Therefore, it is important that the TS4000 is setup so that its...
Watertight Case interface connector (See Appendix A - Serial Port). A variety of antennas can be used with the TS4000, but it is important that the Antenna Connector antenna provides a 50 ohm load at the radio’s operational frequencies. In addition, all cabling used with the antenna must be good quality coaxial cable with 50 ohm impedance.
Watertight Case connector. Fuses The TS4000 has an internal 4 amp fuse for each of the three possible power connections. The power source used with the TS4000 should also be fused with an in-line power fuse. The preferred method of mounting the TS4000 is to use the mounting bracket Mounting supplied with the modem.
Teledesign for ordering information. The remote diagnostics can be accessed using the Remote Diagnostics screen in the TS4000 Configuration Program and can be operated through either serial port. For more details see Remote Diagnostics. Teledesign provides wireless range estimation software called AirCalc.
The TS4000 has three lights (LED) indicators to provide operational status of Status Lights transmit (TX), receive (RX) and power (PWR) functions. Special combinations of these indicators are used to indicate secondary operating modes and fault conditions. TS4000 State LEDs...
3) Follow the installation instructions. Serial Cable TS4000 to PC To transfer configurations between the TS4000 and a PC, their serial ports must Connection be connected together. The serial cable used should be a standard straight through (i.e. pin 1 to pin 1, pin 2 to pin 2, etc) serial cable. This is the same type of cable used to connect a PC to a standard phone modem (See Serial Port).
The configuration of the TS4000 can be read out of the modem by selecting the Programming and Retrieve Configuration command from the Modem Retrieving menu or by pressing the Retrieve Configuration button. Configurations To program a configuration into the TS4000, use...

These include details on the firmware version and memory Screen configuration. These modem hardware values are set at the factory based on the modem hardware included in the TS4000 and cannot be changed. Choose the Retrieve Radio Hardware menu to read and display the radio Radio Hardware hardware details.
The serial port provides an asynchronous data connection between the TS4000 and the host equipment. The TS4000 serial port is a standard RS-232 serial port with a number of options to allow connection to a wide variety of serial host equipment.
The TS4000 with the standard case uses two 9 pin subminiature D connectors Connector with female pins for the serial ports. The TS4000 with the watertight case uses a 19 pin environmentally sealed LEMO connector (see Appendix A - Serial Port).
RI pin is normally left unconnected. RI for Modem Power As an alternative, the RI pin can be connected as a power pin into the TS4000. This is non-standard use of this pin and therefore care should be taken when connecting the TS4000 to other serial devices.
Protocol Options Hardware Handshake In this mode the RTS handshake line is used to frame transmit data into bursts. The TS4000 begins transmission when RTS is activated and at least one character (non-control string) is received. Transmission ends when RTS goes inactive and the burst has been completely transmitted.

TS4000 can correctly demodulate the incoming data. When using the TS4000 in a high noise environment, this level can be raised so that the TS4000 is more selective about the signals that it attempts to demodulate.
When clear channel scan is enabled, all of the TS4000s (both transmitters and receivers) constantly scan the channels of the scan list looking for valid TS4000 transmissions and also looking for interference (noise or transmissions from other sources).
Page 31
Transmit Timeout Timer specified period of continuous transmission. This is used to avoid locking up the radio channel due to a continuous transmission caused by a fault in the TS4000 or the host equipment. When enabled, the TS4000 does not receive and will transmit regardless of Transmit Only Operation activity on the channel.
Page 32
When enabled, the TS4000 will not transmit data sent to it through the serial port. Receive Only Operation Transmit Power This sets the transmit power level. The maximum transmit power that can be set depends on the specific radio module in the TS4000. Therefore the maximum value that can be set is listed only when the configuration program is connected to the TS4000.
The TS4000 comes in various frequency bands (i.e. 450 to 470 MHz) and can be Frequency programmed for any valid channel within a given frequency band. The TS4000 Programming can be set for up to 99 channels. A channel consists of a receive frequency and a transmit frequency which can be set to the same or different frequencies.
The minimum and maximum frequencies and the channel spacing depend on the specific radio module in the TS4000. The configuration program does not know this information unless it is connected to the TS4000. Therefore, these fields in the Radio Settings frame only show up when the configuration program is connected to the TS4000.
RX and TX lights will alternately flash. The channel that the TS4000 activates at power up depends on the setting of the Channel at Power Up Frequency Channel at Power Up control (see Radio Setup – Frequency Channel at Power Up).

TS4000 can correctly demodulate the incoming data. When using the TS4000 in a high noise environment, this level can be raised so that the TS4000 is more selective about the signals that it attempts to demodulate.
To start AirTest press the AirTest button on the main screen of the configuration program. For details on using AirTest consult AirTest’s on line help. To test the operation of the TS4000, AirTest can be used to pass data between Data Test two modems.
AirTest can be setup to run a BER test. To run a BER test, the TS4000s must be configured with packet operation disabled. This is because when the TS4000 is setup for packet operation it discards corrupted packets and does not send them out the serial port.
AirScan enables the TS4000 to be used as a frequency scanner. AirScan is AirScan useful for determining the frequency and magnitude of potential interference within the TS4000’s frequency band. To start AirScan press the AirScan button on the main screen of the configuration program.
Remote diagnostics is available while the host system is in operation and can be accessed through serial port 1 or 2 of the TS4000. The remote diagnostics screen is accessed from the main screen of the TS4000 Configuration Program.
