TS-2030EN/TS-2076EN Series Progressive Scan Cameras
Camera Features
FTP server's IP address, username, password, and subdirectory name must be properly set by FTP
command. Additionally, a 2nd FTP server is supported in case the 1st FTP server is accidentally down.
Please refer to the “EN-to-LC Interface” document for the FTP command.
Additionally, the FTP server must be properly set up. Make sure to create a username and password,
and to allow read/write/modify access so that the EN camera can write image files in the sub-directory
of the FTP server's hard disk. FTP server's hard disk must be regularly cleaned up, otherwise hard disk
capacity becomes full and EN camera cannot write image files.
The default FTP port is 21, but the user can change this port number. Please refer to the
Troubleshooting section for various FTP server performance tests.
6.11 NTP (Network Time Protocol)
TS-2030EN/TS-2076EN supports the NTP (Network Time Protocol) client. NTP is the industry-
standard time synchronization mechanism over the network. For LAN, the synchronization accuracy
within a few milliseconds is achievable. Normally, the EN cameras can maintain the accuracy within
10ms as a worst-case scenario in LAN.
All NTP setup can be done using the EN setup software.
Using the EN setup software, user can access to “NTP client enable” config register (address = 60) to
turn ON or OFF the NTP feature. EN camera supports up to 3 NTP servers’ IP addresses (Config
register address = 61, 62, and 63).
For the first time when the EN camera is set up for NTP, the EN camera optimizes the drift of the
internal clock with regard to the NTP server in your LAN. This takes approximately 1-2 hours to reach
within a few millisecond range of the estimated error. This Drift file is saved in non-volatile memory
and when power is recycled, the EN camera will read the saved NTP Drift file and the next settlement
will not take too long.
If NTP is still not synchronized with the NTP server(s), “NTP status” register (address=239) shows
“UNSYNC” status (=0x40). After NTP is finally synchronized with NTP servers(s), “NTP status”
register shows “PLL” status (=0x01) and “NTP Estimate Error” status register (address=238) shows the
estimated clock drift from the NTP server(s).
If the “NTP Estimate Error” exceeds the values predefined in the “NTP Max Estimate Error” config
register (address = 64), then the EN camera sends an error message to the lane controller or any client
connecting to EN camera. Please refer to the “LC-to-EN Interface” document for details about this error
message.
If you decided to turn OFF the NTP feature, please keep in mind that clock drift is approximately 1.5
second per day. Therefore, you need to send an Ethernet command to synchronize the clock from host
PC on a regular basis (twice a day, every day, or every few days). Write “Real Time Clock UTC”
register (Address = 102). Please note that the internal millisecond counter is reset to zero when you
write a new value to the “Real Time Clock UTC” register.
