3 september 2015 2. Components here are the main components needed for a rain bird ® irrigation system with link900 wireless communications: central control computer: interface(s): maxi ® interface module (mim-link) or two-wire interface (twi-link) link900 radios: par+es (link) controllers: standalo...
4 september 2015 3. Radio basics link900 wireless communication works by broadcasting radio waves to communicate between the central control and field controllers. The link900 system uses custom designed frequency hopping spread spectrum radios (fhss). Key advantages: - no fcc license required for o...
5 september 2015 directional antenna (yagi): the yagi antenna is typically used to focus the signal towards a single point and to minimize interference to and from other radios. Yagi antenna, 6db (gsp-yagi-6) b) antenna field patterns: each type of antenna has a defined field pattern. This indicates...
6 september 2015 c) antenna cables: cable selection is very important as too much signal loss can affect the overall communication performance. In general, lower loss cables tend to be larger in diameter and less flexible. Lmr type cables are more weather resistant than rg type cables, but rg type c...
7 september 2015 e) adapters: in some cases, adapters may be required to accommodate the different antenna and cable terminations used. However, the use of adapters should be minimized, as each adapter causes a signal loss of ~0.25db. Rain bird recommends using cables made with the proper connector ...
8 september 2015 4. Component setup proper installation of all components is key to having a robust system. This section will cover in detail all the steps needed to properly setup link900 wireless communication for your rain bird ® golf irrigation system. A) mim-link / twi-link interface connection...
9 september 2015 programming: the link900 radios supplied with h49001, h49004, and h49008 are identical and interchangeable. However, the programming in them will vary depending on the function of the radio. The link900 radio located at the mim / twi will always be programmed as the master (m) radio...
10 september 2015 upon successful connection to the link900 radio, the general information will populate with the radio’s serial number, network address, firmware revision level and other details. This information may be updated at any time by clicking on the refresh icon. Device type com port seria...
11 september 2015 for the master radio at the mim-link / twi-link, the settings should be as follows:.
12 september 2015 *please note that the “network address” shown in the configuration settings/network needs to be the same in all the radios that will be used by the field controllers. That “network address” is a user definable 4-digit number. Using the last 4 digits of the serial number of the mast...
13 september 2015 switch #1 and #2. It is recommended to never leave the group at “0” in the system information menu. *please refer to section 5 – operation for more information on group settings always ensure that dip switches #3 and #4 are in the “off” position. Also ensure that the orange power c...
14 september 2015 for remote radios at satellite locations, the settings should be as follows:.
15 september 2015 set the baud rate for the link900 radio in the command line mode under the utilities menu. Type “baud 600 8n1” and enter. Confirm the baud rate is set to 600 8n1 by typing “baud” and hitting enter. Confirm the port is set to ttl by typing port and hitting enter. Port ttl should be ...
16 september 2015 programming extension (x) radios: remote radios are programmed with the ge mds element manager utility. Follow the same steps as programming the remote radio, but use the settings below:.
17 september 2015 set the baud rate for the link900 radio in the command line mode under the utilities menu. Type “baud 600 8n1” and enter. Confirm the baud rate is set to 600 8n1 by typing “baud” and hitting enter. Confirm the port is set to ttl by typing port and hitting enter. Port ttl should be ...
18 september 2015 d) programming the par+es controller the par+es controller must also be configured for communication with the central computer via the link900 radio. A properly programmed par+es controller will: • receive control information from the mim-link in the form of start and stop commands...
19 september 2015 the maxi® interface board (espmibl) in the esp-satl controller is a circuit board mounted on top of the output board. Espmibl output board link900 radio the link900 radio is connected to the espmibl via a 9-pin serial cable. The link900 radio kit for small pedestals (h49004) includ...
20 september 2015 on the back side of the esp-satl faceplate, there is a small compartment. Make sure that the “maxicom / stand alone” switch is set to “maxicom”. The channel id is set using the programming dial on the front of the faceplate. From the “time / calendar / channel” position. Press the ...
21 september 2015 each esp-satl controller can have up to two sensors connected. Both sensors will use the first channel id configured on the esp-sat-link. In the central control software, the sensors will be identified as a or b. Below is an example using a rain can connected to the sensor input #1...
22 september 2015 5. Operation the following provides a brief overview of the operation of the proprietary link communication protocol: communication protocol: 1. All link communication is a two-way polled master/slave type a. The mim-link / twi-link is the master b. Satellite controllers are slaves...
23 september 2015 example: if three 48 station controllers and one 72 station controller make up a complete system, the following channel id configuration for these controllers would comply with this recommendation: o controller #1 (48 stations): channel id 1 and 2 o controller #2 (48 stations): cha...
24 september 2015 6. Troubleshooting this section will cover basic troubleshooting techniques for the link900 communication system. Please note that this section is intended to help solve common issues. Complicated issues might require a call to your rain bird ® distributor. Most failures are first ...
25 september 2015 responses from sat: indicates the number of responses the mim/twi heard back from the channel after being called. A low number or a zero indicates that either the controller is not responding or the mim/twi is not hearing the response. Total calls heard: this number indicates the t...
26 september 2015 if only a single controller is showing issues (note that the diagnostics could be showing issues with multiple channels as a par+es can use up to 3 channels), look at the link diagnostic and try to determine if it is a receiving or transmitting issue. O have site conditions changed...
27 september 2015 at the faulty controller: • make sure that the group and channel id are correctly defined in the “system information” of the faceplate • verify the status of the “maxi ® mode led” on the faceplate o on – locked to the mim/twi via the link900 radio o off – not in maxi ® (or centrali...
28 september 2015 either the channels in this controller were not polled during this sequence, or the controller did not receive the poll message. • check the group and channel from the faceplate to insure the controller is properly programmed..
29 september 2015 7. Appendix a) sensors on the link900 system sensors can play a very important role when using a golf central control. Here are some examples of sensors and reasons to use them: 1) flow sensors: allows the user to monitor flow at a pump station, monitor transfer pumps, etc. 2) temp...
30 september 2015 pulse sensors: these sensors deliver a pulse output. The rate of the pulses will change based upon varying conditions.
