4.2.4 EDID Management
VL120014 provides with convenient EDID management to create effective
communication between the display and sources.
In factory default status (Status: 0000), VL120014 pass through the signals directly,
input& output device process the signal automatically. You can invoke other saved EDID
data by adjusting the 4-pin EDID DIP switcher or sending corresponding RS232
command.
4.2.4.1 Via RS232 commands
Dial the switchers to “1111” to enable software EDID management.
Invoking embedded EDID data:
Send command “EDID[X]B[y].” to enable input to invoke embedded EDID data of
VL120014. For example, send “EDID[4]B[3]” , the INPUT device (4) will gain embedded
EDID data is that 720P 2D 2CH.
EDID Copy:
Send command “EDIDM[X]B[y].” to enable input to copy the EDID data of a display. For
example, send “EDIDM[1]B[4]” , the INPUT device (1) will gain EDID data from
OUTPUT device(4).
Program Customized EDID data:
Besides 10 kinds of embedded EDID, this product can program 3 kinds of customized
EDID data.
① The EDID dial switch should be make sure on the “1111” status.
② Copy customized EDID data file (.bin) to the control device (e.g. a PC)
③ Running the RS232 control software, and then send the command
EDIDUpgrade[X], X is 12, 13, or 14, for example, send EDIDUpgrade[12].
④ According the prompt and send custom EDID data file.
⑤ When prompt “Update success”, the custom EDID data are set successfully.
⑥ Send the command EDID[1]B[12], the 1 input channel can invoke this new
customized EDID data.
4.2.4.2 Via 4-pin EDID DIP switcher
Beside EDID can be managed via RS232 commands, VL120014 boasts a 4-pin EDID
DIP switcher to manage EEID. Dial the switchers to invoke demanded EDID data
Embedded EDID data: 10 sets in total, the chart below illustrate the 10 Embedded

4.3 TCP/IP Control
4.3.1 Control Modes
TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and Serial Port is
4001. IP can be changed as you need, Serial Port cannot be changed.
Controlled by single PC
Connect a computer to the TCP/IP port of the VL120014, and set its network segment to
the same as the default IP of the VL120014 (192.168.0.178).
18
Figure 4- 3 Modify the IP of PC
Controlled by PC(s) in LAN
The VL120014 can be connected with a router to make up a LAN with the PC(s), this
make it able to be controlled in a LAN. When control, just make sure the VL120014’s
network segment is the same with the router. Please connect as the following figure for
LAN control.
Figure 4- 4 Connect to LAN
Step1. Connect the TCP/IP port of the VL120014 to Ethernet port of PC with twisted
pair.
Step2. Set the PC’s network segment to the same as the VL120014. Do please
remember the PC’s original network segment.
Same network
segment as the
switcher
19
Step3. Set the VL120014’s network segment to the same as the router.
Step4. Set the PC’s network segment to the original one.
Step5. Connect the VL120014 and PC(s) to the router. In the same LAN, each PC is
able to control the VL120014 asynchronously.
Then it’s able to control the device via a TCP/IP communication software.
4.3.2 Control VL120014 via TCP/IP communication software
(Exampled by TCPUDP software)
1) Connect a computer with TCPUDP software to VL120014. Open the TCPUDP
software (or any other TCP/IP communication software) and create a connection,
enter the IP address and port of VL120014 (default IP: 192.168.0.178, port:8080):
