Apply DC 5V or 12V to the power jack. One and only one DC power source is enough. 1. HV-320E/EH can support either 5VDC or 6~16 DC input. 2. For HV-320 with PA900/PA1200/ PA2400, it’s recommended to use 12V DC only. (DC-in higher than 12.5V will damage the PA!!!) After power on, the default transmission channel is CH 21, 474 MHz / 8MHz BW.
Easy HD Expressway! Configure the Transmission parameters The parameters can be configured with a PC tool, AVSenderUARTGUI.EXE. Connect the USB UART dongle to a PC and the UART pin headers to HV-320. HV-320 UART Configuration Port USB UART Dongle To PC USB The wire connection between HV-320 and UART dongle is shown below.

2. If it still fails to run AVSenderUARTGUI.exe after running step 1. A. Please try to remove manually all the installation of "Microsoft Visual C++ 201x Redistributable" on your PC in Control Panel first, as shown in the picture below. B. Then, run step 1 to install the components again. WWW.HIDES.COM.TW...

Select the correct com port for the USB UART cable. Click on “Open/Close” button to connect HV-320. In the “MediaConfig” page, please click on “GetMediaConfig” button first. You can configure the “Max Bit Rate” for video compression. When configuration is done, click on “SetMediaConfig” button to set HV-320. WWW.HIDES.COM.TW...

In the “TransmissionConfig” page, please click on “GetTransConfig” button first. You can configure the Channel number or the transmission parameters. When configuration is done, click on “SetTransConfig” button to set HV-320. If you want to input frequency and bandwidth manually, please select Channel# 0.

For example, if Max Bit Rate(Mbps)=2 Mbps, Modulation Data Rate (Mbps) should be better >=2.4Mbps. In the “TSInfo” page, please click on “GetTsInfoConfig” button first. You can configure the service name and PID assignments. When configuration is done, click on “SetTsInfoConfig” button to set HV-320. WWW.HIDES.COM.TW...
Easy HD Expressway! Backup and Restore DC Calibration Table For each HV-320, a specific DC calibration table is kept in the NOR flash to optimize the DC LO leakage. This paragraph describes how to back up and restore the DC calibration table.
The firmware update process may corrupt the DC calibration table in the NOR flash. Copy the firmware image file “jedi.img” to the root directory of a micro SD card. Power the HV-320 box down. Plug in the micro SD card...
Page 12
Remove the micro SD card, power off, then power on the transmitter box. Note: 1. Jedi.img will be rename to jedi_tmp.img when update is done. After firmware update, please check if the DC table still exists. If not, it’s recommend to restore the DC calibration table. WWW.HIDES.COM.TW...
You may dump debug messages from this J9 pin2 UART-1 Tx. Pin 1: UART-1 Rx (Data mux input, described below) Pin 2 :UART-1 Tx (for Debug message output, GPIO28) Pin 3: Ground The communication parameters for UART-1 are 115200,n,8,1. Tx Gnd WWW.HIDES.COM.TW...

Then, click on “Set SerialPortConfig” button. Note: If you have changed the communication parameters (Baudrate/Data bit/Parity/Stop/Flow control), 1. You should reboot HV-320 for the new setting to take effect after clicking the “Set SerialPortConfig” Button 2. The debug message port UART-1 Tx’s communication parameters are also changed because it’s the same UART-1.

Easy HD Expressway! Shorten receiver latency with HV-110 HD box If you are testing HV-320 Tx latency with HV-110 Rx, you may get a special firmware from Hides for HV-110 Rx. The special firmware for HV-110 Rx can decrease the receiver latency very much.
2. Enable Data Encryption Mode 3. Input the key, it’s a 32-digit HEX number. 4. Set the new settings to HV-320 Tricks for smoothing the video motion If there are large motions in the video input, the encoded stream may have glitches and stutter on the TV.

(compression) "Max bit rate(kbps)" is 8000Kbps, modulation data rate is recommended to be 12000Kbps. Change the transmission parameters properly to fit this requirement. C.In TSInfo Page: Increase "PTS PCR Latency (ms)" to a larger value, say 1000ms or larger. WWW.HIDES.COM.TW...
Valid frame rates are 23, 24, 25, 29.97, 30, 59.94 and 60 FPS. Note: For 1080P video, the maximum FPS allowed is 30FPS. Some TV’s cannot take 1080p30 well (video glitch or lip-sync failure) , please force the frame rate to 29.97. WWW.HIDES.COM.TW...
