Setup The Communication

User can send messages to one sign, and can also send the same messages to many signs with same or different communication modes. Following we will introduce the communication setup by three states.
1> Send messages to one sign
Select menu Comm|Setup Comm.

Setup For RS232/RS422/RS485/Modem

Protocol | Select the protocol of sign.
Sign Address | The sign address who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs in the same group can receive messages and do not response.
Sign Group | The group of signs who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs with the same address can receive messages and do not response.
COM Port | The com port such as COM1,COM2,... Choose from the drop list box or enter a name directory.
Baud Rate | Select the communication speed. You can try a lower speed or use RS422 interface instead of RS232 if the connection distance is long and communication often timeout.
Dial Modem | Enter the phone number and click the Dial or Hung Up button. If use some phone numbers, they will be saved in drop list box. When use these numbers again, you can select them from the drop list box. When adopts Modem communication, you can also click the Dial or Hung Up button in toolbar.

Setup For TCP/IP Connection

Choose TCPIP for COM Port.

Protocol | Select the protocol of sign.
Sign Address | The sign address who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs in the same group can receive messages and do not response.
Sign Group | The group of signs who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs with the same address can receive messages and do not response.
Remote Host | The host name of the TCP/IP receiver. It must be a TCP server such as NetJet, which is a TCP/IP to RS232 converting box.
Remote Port | The service port of the TCP/IP-RS232 adapter.
Setup For GPRS Connection
Before using GPRS DTU communication mode, user needs to insert SIM card into GPRS DTU, the SIM card has registered GPRS function, then connect the GPRS DTU to COM port on PC by RS232 cable, power on the GPRS DTU, and configure it (Please refer to GPRS configuration instruction by we provide when configure the GPRS DTU).
After configurating GPRS DTU, connect it and LED sign by RS232 cable, and power on the GPRS Modme. Run WZP Sign Software, Choose GPRS for COM Port.
Protocol | Select the protocol of sign.
Sign Address | The sign address who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs in the same group can receive messages and do not response.
Sign Group | The group of signs who can receive messages and response. Enter a value from 0 to 255. A zero value means that all signs with the same address can receive messages and do not response.
Setup GPRS | Click this button to setup GPRS. It will appear the following dialog box.
User needs to input the GPRS service port in text box, and click "Start GPRS Service" button to start GPRS service.
Note: If select "Automatically Start GPRS Service" option, user doesn't need to setup GPRS when choosing GPRS DTU communicaiton mode next time, the software will start GPRS service automatically.
GPRS Client | Current communicating GPRS device name.
All GPRS devices which connect to GPRS service port will be displayed in the list box after starting GPRS service, it includes GPRS device name, IP, phone, type and ID, and it may have many devices. When there are many devices, user needs to click one device in list box to make the device change to the current device, the device name will be displayed in "GPRS Client" box.
Note: In this state, the target signs option is empty.
2> Send the same messages to many signs with same communication mode
First, user needs to create address book.
Click in above figure, it will popup the address book edit box as following figure.
Some buttons:
New ¨C Click this button to create a new address.
Edit ¨C Click this button to edit the existing address.
Delete ¨C Click this button to delete the existing address.
Save ¨C Click this button after setting all parameters to save the setting, the address will be displayed in address book list box.
Close ¨C Click this button to exit the address book edit box.
Some parameters:
Interface ¨C Communication mode, it includes RS232, RS422, RS485, MODEM, TCPIP, GPRS.
COM Port ¨C Communication serial port, it includes COM1, COM2.
Baud Rate ¨C Communication baud rate, it includes 2400, 4800, 9600, 14400, 19200, 28800, 57600, 115200. User needs to select the corresponding sign's baud rate.
Address ¨C Address number, all signs' address must be different.
Name ¨C The name of the sign.
Location ¨C The location of the sign.
Group ¨C There are many signs in one group.
Following will introduce address book edit method for different communication modes.
• RS232 mode
Click New button in above figure, select RS232 for interface, and select COM port and baud rate, input address, name, location, group, lastly, click Save button. Please refer to the following figure.
Note: The address book edit for RS422/485 mode is similar to RS232 mode, their different is external connection, and it needs one RS232 ¨C RS422/485 adapter between PC and LED sign for RS422/485 communication mode.
• MODEM mode
Click New button, select MODEM for interface, and select COM port and baud rate, input phone number, address, name, location, group, lastly, click Save button. Please refer to the following figure.
Note: When use MODEM communication mode, in LED sign end, there can connect many signs behind one MODEM, and each sign can also connect one MODEM.
• TCP/IP mode
Click New button, select TCPIP for interface, and input IP address for Remote Host (IP address of TCP/IP adapter) and remote port, and then input address, name, location, group, lastly, click Save button. Please refer to the following figure.
Note: When use TCP/IP communication mode, in LED sign end, there can connect many signs behind one TCP/IP adapter, and each sign can also connect one TCP/IP adapter.
• GPRS mode
Click New button, select GPRS for interface, and select DTU name, DTU IP and phone number, input address, name, location, group, lastly, click Save button. Please refer to the following figure.
Note: When use GPRS DTU communication mode, in LED sign end, there can connect many signs behind one GPRS DTU, and each sign can also connect one GPRS DTU.
Second, select group from the Target Signs drop list box for the target signs. Please refer to the following figure.
Note: There may be many signs in one group. When there are many groups in the address book, select All for target signs to send the messages to all signs.
3> Send the same messages to many signs with different communication modes
For example, send messages to sign 1 by RS232 mode, and send messages to sign 2 by MODEM mode, send messages to sign 3 by TCP/IP mode, send messages to sign 4 by GPRS DTU mode.
Step1: Click New button, select RS232 for interface, and select COM port and baud rate, input address, name, location, group, lastly, click Save button.
Step2: Click New button, select MODEM for interface, and select COM port and baud rate, input phone number, address, name, location, group, lastly, click Save button.
Step3: Click New button, select TCPIP for interface, and input IP address for Remote Host (IP address of TCP/IP adapter) and remote port, and then input address, name, location, group, lastly, click Save button.
Step4: Click New button, select GPRS for interface, select DTU name, DTU IP and phone number, input address, name, location, group, lastly, click Save button.
Please refer to the following figure.
Step5: Select group from the Target Signs drop list box for the target signs.
Note: There may be many signs in one group. When there are many groups in the address book, select All for target signs to send the messages to all signs.
