Direct IP programs to communicate with the asynchronous serial ports on the ESP904. In this type of application the ESP904 is configured as a TCP or UDP server. The socket program running on the PC establishes a communication connection with the ESP904. The data is sent directly to and from the serial port on the server.
All manuals and user guides at all-guides.com Introduction To use this mode, the ESP904 must be set to either TCP/server or UDP/server with a designated communication port number. The virtual COM driver is the TCP or UDP client. Paired Mode is also called serial tunneling.
Hardware Setup Figure 1. Quick Start Hardware Setup Step 1: Connect the ESP904 to the network using a standard network cable Step 2: Connect the ESP904 to the RS-232 serial device. If the serial device is configured as a DCE use a straight-through serial cable. If the serial device is configured as a DTE use a crossover (null modem) cable.
Serial Servers connected to the LAN will appear in the window. Serial Server List Step 2: Double click the first ESP904 port on the list (4000) to bring up the configuration screen. Server Properties Figure 2. The Server Properties Window Step 3: Change the as required.

RJ-45 receptacle mounted in the top edge of the ESP904 chassis. The ESP904 can be connected to an Ethernet hub, switch, or wall plate using a standard straight-through RJ-45 (male) Ethernet cable. To connect directly to an RJ45 Ethernet port on a PC or laptop a crossover Ethernet cable must be used.
Figure 4. Top View of the ESP904 Serial Ports The ESP904 has four serial ports, each configurable through software as RS- 232, RS-422 or RS-485 interfaces. When in RS-232 mode the interfaces are configured as DTEs (Data Terminal Equipment).The connectors are DB-9M.
In Upgrade Mode firmware can be uploaded from a PC via its serial port to the ESP904 Port 1, using RS-232. Upgrading also can be via the network connection, using the ESP Manager software and a virtual COM port mapped to the ESP904 Port 1.

If a DHCP server is not available on the network the ESP904 will time out after 10 seconds and the default values will remain. A dynamic address assigned by the DHCP server may change if the ESP904 loses the Ethernet connection or power is removed.
Click Update to store settings for each port before changing to the other port. Baud Rate The serial port baud rate on the ESP904 must match the serial baud rate of the connected device unless using Virtual COM mode. In Virtual COM mode the software program will establish serial settings.
In all modes of operation, , the port number set in Direct IP Virtual COM the ESP904 menu must match the Virtual COM or socket software port settings. Example: The Virtual COM default setting is TCP/UDP Port 4000. If the port # property is changed to 4001, the virtual COM port will have to be changed to 4001.
This is a security feature activated by entering the IP address of the desired client. The ESP904 will only communicate with the listed IP address and all other requests for connection will be filtered out. The ESP904 must be set up as a to use this feature.

For example, in a computer already having a COM1 and COM2, COM3 to COM 254 is available for the ESP904. It is recommended that COM Port 5 or higher be selected. The virtual COM port looks like a standard COM port to most Windows based applications which allows the software to open a connection with the serial port located anywhere on the LAN/WAN.

Upgrading Via ESP Manager The ESP Manager software can upload new firmware to the server using a direct PC connection via Port 1 of the ESP904, or using a virtual COM port mapped to Port 1. If connecting directly to a computer serial port, connect a null modem cable between the Computer RS-232 port and the ESP904 Port1 serial port.
If connected directly from the computer to Port 1 of the ESP904 the port will typically be COM1 or COM2 b. If using a virtual COM port to upgrade via the network, identify the virtual COM number and address mapped to Port 1 on the ESP904.
