2. Verify that the RS-232 connector on the cable supplied will fit the interface on the instrument to which it is being connected. All Thermo Scientific Chit cables should meet this requirement 3. Attach the antennas or antenna cables, as needed, insuring they are snug and properly seated. -
Page 12: Tuning Transceiver Performance
3.0 TUNING TRANSCEIVER PERFORMANCE AutoWAVE allows you to tune several parameters to optimize its performance for your particular application. All adjustments are done through the AutoWAVE setup program, a user interface which eliminates the need for setup diskettes, dipswitch settings, or custom software. The setup program is started by connecting AutoWAVE to any terminal program, setting the baud rate for that terminal to 19200 baud, and using a small pointed object to press the Setup Button on the side of the enclosure. -
Page 13: 0)Set Operation Mode
3.1 (0) Set Operation Mode When item (0) is selected the Operation Mode appears as shown in figure 2. The Operation Mode option is used to designate the method in which the particular AutoWAVE Transceiver will be used. AutoWAVE operates in a master to slave configuration; therefore, any transceivers which are intended to operate together must be set up as such. -
Page 14: Operation Mode Selections
4.0 OPERATION MODE SELECTIONS (0) Point-to-Point Master AutoWAVE operates in a master/slave configuration. When designated as a master in Point- to-Point mode the transceiver, will call any or all slaves it is instructed to call in the call book. The master determines the settings used for all Radio Transmission Characteristics, regardless of the settings in the slave and/or repeaters. -
Page 15: Point-To-Point Repeater
(5) Point-to-Point Repeater AutoWAVE allows the use of up to two repeaters in a communications link, significantly extending the operating range. When designated as a repeater a transceiver behaves as a pass-through link. All settings for the call book, baud rate, and radio transmission characteristics are disabled. - Page 16 The following steps show how to establish a pcANYWHERE entry using AutoWAVE. 1. Enter a new entry under Call a Host PC. It may be of value to give this entry a name which will be easily remembered (such as Office Computer). 2.
- Page 17 When pcANYWHERE is instructed to call a Host PC corresponding to an entry that has been established with the above instruction, the following should occur: ‚ pcANYWHERE should go into terminal mode ‚ A series of OKs should appear in the terminal window (one OK for each line of the script file being run).
- Page 18 Using Mode 6 to call a transceiver not listed in the Call Book Mode 6 will accept the command ATD####### where #######is any arbitraary modem ID (serial number) such as 2340179. Upon receipt of this command the modem will call that modem even though the number is not in the sending modem’s Call Book.

Page 20: Multipoint Operation
5.0 MULTIPOINT OPERATION In a Multipoint system a transceiver designated as a master is able to simultaneously be in communication with numerous slaves. In its simplest form, a Multipoint network functions with the master broadcasting its messages to all slaves and slaves responding to the master as appropriate. -
Page 21: Max Slave Retry
(2) Max Slave Retry (3) Retry Odds While packets transmitted from the master to the slaves in a Multipoint network are not acknowledged, packets transmitted from slaves to the master are. However, it is possible that more than one slave will attempt to transmit to the master at the same time, and it is therefore important that a protocol exists to resolve contention for the master between slaves. -

6.0 BAUD RATE SELECTIONS (1) Set Baud Rate When item (1) is selected you will be able to change the transceiver’s RS-232 baud rate; the communication rate between the Transceiver and the instrument to which it is connected. It is important to note that this is independent of the baud rate for the other transceiver(s) in the communication loop. -

Page 25: Call Book Selections
7.0 CALL BOOK SELECTIONS (2) Edit Call Book The Call Book is an innovative feature in AutoWAVE which offers both security and flexibility in use. The Call Book accomplishes this by allowing the user to determine with which other AutoWAVE Transceivers a given transceiver will communicate, based on the ID numbers for both the master and slave. - Page 26 Standard Hop Table Modem Serial Number 571-1001 (0) Set Operation Mode (1) Set Baud Rate (2) Edit Call Book (3) Edit Radio Transmission Characteristics (4) Show Radio Statistics (5) Edit Multipoint Parameters (6) TDMA Menu Enter Choice MODEM CALL BOOK Entry to Call is 00 Entry Number Repeater 1...
- Page 27 Note:It is important that the Call Book slots (0-9) are filled sequentially beginning with 0, the first slot in the book. ID numbers do not need to be entered in numerical order, however, there must not be any 000-0000 numbers in the middle of the lists of good ID numbers. The reason for this is that when a master is instructed to Call All available slaves it will call all slaves listed until it reaches the first number of 000-0000.

8.0 RADIO TRANSMISSION PARAMETERS (3) Edit Radio Transmission Characteristics When item (3) is selected in the main menu the screen in figure 7 appears, which allows the user to modify the radio transmission characteristics of the Transceivers. As stated in the warning, these parameters are for the sophisticated user who has a good understanding of the principles of radio data transmission. -

Page 31: Xmit Rate
(3) Xmit Rate There are two settings for the Transmit Rate parameter. For normal operation AutoWAVE should be set at Transmit Rate 1. Transmit Rate 0 is useful to qualitatively gauge signal strength. When set to Transmit Rate 0 the transceivers will transmit data back and forth continuously, and the strength of the signal may be gauged by the Clear to Send LED. -
Page 32: Slave Security
(6) Slave Security With option 6 the user may disable the transceiver’s security so it will accept a call from any other AutoWAVE unit. The default setting is 0 where security is enforced (the caller’s ID number must be in the slave’s Call Book), with a setting of 1 security is disabled As mentioned in mode 6, slave Security must be set to 1 when the unit is operating in a Point-to-Point system where it may need to accept calls from more than 10 different AutoWAVE transceivers. -
Page 33: Retry Time Out
(8) Retry Time Out The Retry Time Out parameter allows the user to determine when a slave will drop a connection to a master or repeater in Multipoint mode. The default setting is 255, meaning that if one packet in 255 from the master is sent successfully to the slave it will maintain a link. -

Page 36: Using An External Antenna
12.0 USING AN EXTERNAL ANTENNA In certain circumstances it may be desirable to extend the range of the AutoWAVE Transceiver by using an external antenna in place of the standard whip antenna. The transceiver is equipped with a non-standard external jack allowing the use of a directional Yagi or omnidirectional antenna. When using an external antenna the whip antenna must be removed. -

Page 38: Data Communictions Settings
Pin 8: ClearTo Send The signal is used to tell the system device connected to the transceiver that the transceiver is ready to receive data. When asserted, the transceiver will accept data, when de-asserted the transceiver will not accept data. This should always be used for data rates above 38.4 Kbaud or there will be a risk of lost data if an RF link is not very robust. -
Page 39: Establishing Data Communiction Links
15.0 ESTABLISHING DATA COMMUNICATION LINKS AutoWAVE’s versatility allows data communication links to be established using a variety of different configurations. This, in turn, makes it possible to extend the range of the AutoWAVE and get around obstacles. Diagram (A) shows the most common and straightforward link, a master communicating to a slave in a dedicated link. - Page 40 Diagram (C) shows a link with two repeaters between the master and slave. With two repeaters there is clearly more flexibility in getting around obstacles and greater total range is possible. Once again, it would be desirable to use external omnidirectional antennas with the repeaters, and attaching a Yagi to the master and slave would increase the range of the link.
- Page 41 Example (E) depicts a standard Point-to-Multipoint system. In this example any data sent from the master is broadcast to all three slaves, one of which receives it through a multipoint repeater. The data is in turn sent out of the RS-232 port of each of the slaves. Document 1-0479-013 Rev B...

Page 42: Troubleshooting
16.0 TROUBLESHOOTING Troubleshooting the AutoWAVE is much like troulbeshooting most other radio systems. Failure to establish initial communictions is usually a setup problem in the transciever configuration, the PC/Terminal configuration, or a problem with signal range. The transciever range can be severely limited by low voltage from the power source. - Page 43 “I am able to link to a remote unit within line of sight when the transceiver I have is outside. However, as soon as I walk inside with it I lose the link, even if I place the transceiver by the window which faces the remote unit.”...
