Where can I find the current RET Firmware for upgrading the RET-200?
You can download the latest RET-200 Firmware at the link below. Please see: http://info.jmawireless.com/ret-200
Are JMA Wireless RET-200 single or multi-RET?
JMA RET-200 is a single RET, type-1 and has one unique ID per motor. Multi-RETs are type 17 and have one unique ID for multiple motors.
Is the current JMA GUI compatible with all antenna line devices (ALDs)?
The current JMA GUI is compatible only with JMA RETs which are type1, single RETs. Our GUI is NOT compatible with multi-RETs or AISG TMAs.
Are the external RET-200 motors field-replaceable and are there instructions for replacement?
Yes, RET-200 motors are field replaceable. You can download the instructions at: http://info.jmawireless.com/ret-200
Are all external RET-200 motors the same part and are they compatible with all JMA RET antennas (Non-NWAV)?
Yes, all RET-200 motors can be used as a direct replacement but the correct antenna configuration file and updated firmware must be verified. Please contact JMA Tech Support at +1.888.201.6073 with any additional questions regarding the software and antenna files.
How do I select the correct antenna configuration files for the antenna model I'm working with?
Refer to page 10, section V of the PCU-220 User Guide. Please see: http://www.jmawireless.com/products/pcu-220
What 3rd-party RET controllers are compatible with the JMA GUI 4.4?
Commscope ATC Lite -200, Amphenol PCU-4, and RFS - PA-USB/485-2. Ensure that the drivers for each of these controllers are installed on your PC for compatibility.
What is the output voltage of the JMA RET controller and how can that voltage be verified?
The JMA RET controller output is +24VDC. You can verify this by connecting the RET controller to an RET motor and measure the DC voltage on pins 6 & 7 of the AISG connector using a volt meter. You can get the AIS connector pin connections from the RET-200 datasheet. Please see: http://info.jmawireless.com/ret-200
What is the purpose of the provided tube of dielectric grease?
The dielectric grease MUST be applied to all AISG ports to prevent water ingress and corrosion, and no additional weatherproofing should be used.
Is there a specified torque on the AISG connection to the RET ports?
There is no torque specification for the RET cable connection to the AISG port on the RETs/antennas. It should ONLY be hand tightened and no additional weatherproofing should be used.
Is there a particular sequence in connecting the RET controller to a PC and GUI?
Yes, please follow these steps:
1. Power up the RET controller.
2. Connect the USB cable from the RET controller to the PC.
3. Launch the RET Controller GUI and set up the COM port.
4. Connect the RET Controller to an RET motor.
5. Start the RET Scan.
What is the total number of RETs that can be daisy-chained together?
This depends on the RU/RRU manufacturer. Typically, no more than six RETs can be daisy-chained to a single RU/RRU. For ground testing, perform the RET test according to the RET connection diagram for the site.
NWAV Antennas: MX and MC
Which ports have internal Smart Bias-Ts?
Please refer to the RET and RF Connector Topology section of each antenna datasheet. Typically it is ports 1 and 3 on the hex-port antennas and ports 1 and 5 on the octo-port antennas. Please see: http://info.jmawireless.com/ret-antenna-matrix
How do I test the RETs on antennas that are connected through the RF ports with internal Smart Bias-Ts?
A bottom Smart Bias-T is required to inject the DC/AISG to the antenna RF port (e.g. 1, and 3 or 5) with internal Smart Bias-Ts.
Are all of the RETs on the NWAV antennas internally daisy chained?
No, they are not. Please refer to the RET and RF Connector Topology section of each antenna datasheet. The low-band RET(s) are not internally connected to the high-band RETs. On the octo- NWAV antennas, there are two low-band RETs that are internally daisy chained: one for 700 MHz and one for 800 MHz. Please see: http://info.jmawireless.com/ret-antenna-matrix
Can the RETs on the NWAV antennas have multiple DC/AISG feeds?
No. Please ensure there is only one DC/AISG feed to each RET/AISG bus.
How are the antenna arrays positioned inside the antennas?
Please refer to the Array Topology section of each datasheet. Typically the Low band is in the center with the High band on each side.
Please go to: http://info.jmawireless.com/ret-antenna-matrix
How are frequencies assigned to each port?
When testing return loss and PIM, please reference the specified frequency range assigned to each RF port on the antenna. Test results are ONLY valid for the specified range on each port.
How do I update the firmware and antenna files on an NWAV antenna?
There is no need to update the firmware or antenna configuration files on the NWAV antennas.
What 3rd-party RET controllers are compatible with the JMA GUI 4.4?
Commscope ATC Lite -200, Amphenol PCU-4, and RFS - PA-USB/485-2. Ensure that the drivers for each of these controllers are installed on your PC for compatibility.
Are JMA NWAV RETs single or multi-RET?
JMA NWAV RETs are single RET, type-1 and have one unique ID per motor. Multi-RETs are Type 17 and have one unique ID for multiple motors.
NWAV Filters
Where can I find information on the DC/AISG pass-through?
Please refer to the datasheets for each filter on our multi-band combiner matrix. Reference the section on DC Sense and Routing specification and follow the port priority. Please see: http://info.jmawireless.com/products/antenna-systems/filter-matrix
Is there a requirement for mounting the NWAV filters?
The NWAV filters can be mounted in any orientation. Just ensure there are no obstructions to the weep holes.
How do you PIM test filters that have PCS and AWS pass bands?
PIM testing should only be performed on the PCS (1900) ports. The AWS (2100) port cannot be PIM tested due to the 400 MHz separation of the Rx to Tx bands.
Do I have to install DC blocks, or do the NWAV filters auto-sense DC from the RU and allocate appropriately to respective frequency output ports?
NWAV filters use priority based on frequency hierarchy. If there is a conflict (multiple DC inputs from separate radios) it will allocate DC based on the frequency priority.
What if I want to apply DC voltage to a frequency that will not take priority?
You will need to install a DC block(s) on the priority frequency to force the next priority frequency to pass DC voltage.
