Wireless I/O Extender User’s Guide Setup Factory Configuration Process At the factory, each remote unit is given an address, which is zero (0) to seven (7). Each unit is then programmed for a specific number of analog inputs and outputs, which if not specified is an equal number (or as close to) per each remote to use all 8 available channels. The channel fail states are default as: Analog -> 4 mA, Discrete -> Off, Alarm -> LED Only Note: A system will have one Master and 1-8 Remotes.
Wireless I/O Extender User’s Guide Analog Operation (Analog models only) Requirements •The outputs can drive 4-20 mA. •The outputs can operate on loops with a maximum total resistance of 300 ohms. •The input signal must be a 4-20 mA signal. •All inputs use a common ground connection labeled “G”. These units are bi-directional, they send and receive analog information both directions. The analog connection to the device is made via the terminals labeled “4-20mA Input” and “4-20mA Output.
Wireless I/O Extender User’s Guide RF Operation Requirements •Per FCC Rules, the maximum power allowed at the antenna is 4 Watts E.I.R.P. •Maximum RF transmit power is: DD(AA)1000 DD(AA)1000/2.4 PLR580D(A) 955mW 500mW 200mW •Standard thread SMA connection for coax and external antenna connections.

Wireless I/O Extender User’s Guide (4) RF Data Rate •2 when the radios are closer together and data throughput is to be optimized. •3 when the radios are farther away and a solid RF data link is preferred over data throughput. Note: The RF Data Rate setting must be identical for all units in the system. Any radio modem with a different RF Data Rate than the master will not establish a communication link.Sets the RF Data Rate for the over-the-air communications rate.
Wireless I/O Extender User’s Guide RTS line will control all remotes’ CTS lines. When this mode is enabled the CTS line ceases to function as flow control. Therefore it is not recommended to enable this feature when operating at high RS232 speeds. Note: The RTS to CTS feature does not function in point-to-point systems that contain a repeater. If this feature is needed in with a repeater, the system should be changed to a point-to-multiPoint system.
Wireless I/O Extender User’s Guide (A) High Noise Sets the radio High Noise feature. This feature is useful in determining if out of band interference is affecting a radio link. •0 to disable high noise. •1 to use the high noise feature When enabled it reduces the gain in the front-end circuitry, which decreases the affects from out-of-band noise. The results will be seen as a lower signal value and a much lower noise value (as found in Radio Statistics or Diagnostics).
Wireless I/O Extender User’s Guide Menu (4): Show Radio Statistics Number of Disconnects The value records the number of times the radio has lost the RF link and re-establishes a link. The value indicates the total number of disconnects that have occurred from the time the transceiver is powered on until the radio is put into Setup mode. Under ideal operating conditions, the number of disconnects should be 0.
Wireless I/O Extender User’s Guide Rcv Rate of 100% will provide approximately 100 Kbaud of bandwidth with an RF data rate of 3 (Radio Transmission Parameters Menu) and approximately 150 Kbaud of bandwidth with an RF Data Rate of 2. These numbers are reduced approximately 50% if there are one or more repeaters in the network. Menu (5): Edit Multipoint Parameters When installing a Point-to-MultiPoint system, for the system it requires that several parameters be set consistently on all the radios.
Wireless I/O Extender User’s Guide (4) DTR Connect Sets the operation of the radio based of the DTR line. •0 to ignore the DTR line, data is transmitted when it is received. •1 to form a point-to-point link with the Master when the DTR line is high. •2 to transmit data in bursts when the DTR line is high. Use this mode when a system is comprised of many low data rate devices and it is desirable to increase overall system capacity.
Wireless I/O Extender User’s Guide (9) 1 PPS Enable/Delay This mode allows the master to propagate a 1PPS signal to all the remotes in a multipoint network. The properly generated pulse applied on the DTR line of the master will provide a 1 PPS pulse on the CD line of any remote in the system. The output on the Slave will occur within 20 microseconds of the input to the Master. •0 in the master to enable 1 PPS pulse mode. The master must have a 1 PPS pulse on the DTR line.
Wireless I/O Extender User’s Guide •Rcv Options (0 – 9, A - F) / (0 – 15) The channel to listen to. •Xmit Options (0 – 9, A - F) / (0 – 15) The channel to use for transmitting. The default is disable, which is a setting for both Rcv and Xmit of F. The master using this mode should have a setting for both Rcv and Xmit of 0. Note: The Subnet ID only works in a multipoint system using Network ID addressing. Note: The transmit (Xmit) Subnet ID parameter is only used for multipoint repeaters.
Wireless I/O Extender User’s Guide Menu (8): Chg Password Sets a password, which will prevent unauthorized users from making or viewing the configuration of the radio Note: If the password feature is enabled and you cannot remember the password, the radio modem will have to be returned to Data-Linc Group to have the password disabled.
