1 Network Topology
This setup is designed to achieve a video synchronization over Ethernet connection.
It requires one Master unit to control all slave units as a result to sync the video on
the monitors at the same time.
Both Master and Slave unit are required to assign a dedicated IP address (i.e. static
IP)

3 NETCFG.INI and DVSYNC.INI setup
To enable video synchronization feature on VS-700, a special options are required to setup in
NETCFG.INI file. Below is the section to show how to configure a NETCFG.INI for master unit
and slave unit respectively.
3.1 Configure a NETCFG.INI for master unit
Copy all video content on to “media” folder on USB flash drive.
Create a NETCFG.INI and place it in the “media” folder on the USB flash drive.
Update the video content and NETCFG.INI on to the Master unit (VS-700) through
USB update. (see VS-700 user guide)
The NETCFG.INI file contains some system and network settings. The following table
shows the major options required in Video synchronization.
Options in NETCFG.INI
Description
IP_OVERWRITE
0 – Keep old IP address
1 – Use the new IP address
IP
IP address
NETMASK
Subnet Mask Address
GATEWAY
Gateway address

NETSYNC_MASTER_MODE
Master mode enable
(0=disable, 1=enable)
NETSYNC_NUM_SLAVE
The total number of Slave unit in the
LAN.
Below is an example of a NETCFG.INI file for “Master unit”:
IP_OVERWRITE=1
IP=10.1.0.70
NETMASK=255.255.255.0
GATEWAY=10.1.0.1
NETSYNC_MASTER_MODE=1
NETSYNC_NUM_SLAVE=4
Note: All master and slave unit must in different static IP addresses.

3.2 Configure a NETCFG.INI for slave unit
Copy all video content on to “media” folder on USB flash drive.
Create a NETCFG.INI and place it in the “media” folder on the USB flash drive.
Update the video content and NETCFG.INI on to the Slave unit (VS-700) through
USB update. (see VS-700 user guide)
The NETCFG.INI file contains some system and network settings. The following table
shows the major options required in Video synchronization.

Below is an example of a NETCFG.INI file for “Slave unit”:
IP_OVERWRITE=1
IP=10.1.0.71
NETMASK=255.255.255.0
GATEWAY=10.1.0.1
NETSYNC_SLAVE_MODE=1
NETSYNC_MASTER_ADDR=10.1.0.70
Note: All master and slave unit must in different static IP addresses.
Both master and slave unit must contain the same content (but different in playlist
settings – see Section 4).

3.3 Disable the DVSYNC.INI
All VS-700 are shipped with “DVSYNC.INI” disable setting. If this DVSYNC.INI was
enabled, the video sync among master and slaves might not successful.
In case you find the slaves units cannot video sync with each others, please try to
disable the dvsync.ini through the following procedures.
1. Create a dummy DVSYNC.INI (i.e. a blank file) and place it in the “media” folder
on the USB flash drive.
2. Update the dummy DVSYNC.INI on to the Master unit (VS-700) and all Slave unit
(VS-700) through USB update. (see VS-700 user guide)
