1 CHAPTER Introduction 1 Features ESP Ethernet serial hubs contain an autosensing 10/100 Ethernet port and multi-interface (MI) serial ports. MI ports may be configured to use the RS-232, RS-422 or RS-485 physical interface. • The ESP-2 MI hub contains two MI serial ports. • The ESP-4 MI hub contains four MI serial ports. • The ESP-8 MI hub contains eight MI serial ports. • The ESP-16 MI hub contains eight MI serial ports and eight dedicated RS-232 ports.
2 ESP Serial Hub Installer/User Guide For serial port redirection, the ESP hub is configured using the appropriate drivers running on any Microsoft Windows host, or espdiag and espcfg for OpenServer, UnixWare, Linux, Sun or AIX systems. Certain configuration values are set during driver installation. The file-driven ESP-Install program may be used to install, modify and remove Windows drivers for ESP serial hubs without the need for on-site technical personnel. See ESP-Install Program on page 61.
Chapter 1: Introduction 3 The ESP hubs support attended and unattended configuration. With attended configuration, you set values and request actions directly through the web interface or the configuration utility. Unattended configuration uses a flat text file containing configuration commands. The commands are processed as if they were requested using the web interface or the configuration utility. The command file may be read by BootP/DHCP during initial ESP hub configuration.

15 CHAPTER 3 Connection Methods, Attributes and Configurable Features This chapter describes: • Connection methods, which are configured for each serial port • Attributes, which are configured for each serial port • Configurable features, which are enabled/disabled for the entire hub Serial Port Connection Methods There are several methods to access a serial port on an ESP hub.
16 ESP Serial Hub Installer/User Guide • The modem emulation connection method is valid only on an RS-232 port. This method is exclusive; when it is enabled on a port, no other connection methods can be enabled for that port. In any case, a port may be actively open and used by only one method at a time. Serial port redirection The serial port redirection connection method uses an ESP serial redirection driver on a host computer to communicate with the hub.
Chapter 3: Connection Methods, Attributes and Configurable Features 17 Table 3.2 describes this method’s configurable items for each serial port. Table 3.2: Telnet Server Connection Method Configurable Items Item Description Enable/disable Enables or disables the Telnet server connection method on the port. (See Exclusivity and restrictions on page 15.) The default value is disabled. Specifies the IP port number on which the Telnet server will listen.
18 ESP Serial Hub Installer/User Guide open and in use by any connection method, including an existing raw TCP server connection on that port. If the port is currently in use, the connection request will be rejected. The TCP session will remain active until the remote client closes the TCP socket, the TCP connection is broken or the inactivity time-out (if enabled) occurs. Table 3.3 describes this method’s configurable items for each serial port. Table 3.
Chapter 3: Connection Methods, Attributes and Configurable Features 19 Table 3.3: Raw TCP Server Connection Method Configurable Items (Continued) Item Description Specifies the length of time accumulated serial data should be buffered before being sent to the remote server. Valid values are 0-65535 hundredths of a second. A 0 value indicates that data will be sent as soon as it is available.
20 ESP Serial Hub Installer/User Guide Table 3.4: Raw TCP Client Connection Method Configurable Items (Continued) Item Description Specifies the IP port number on which the remote server is listening. Valid values are 0-65535. (If the destination IP port is on an ESP hub, 4000 and 4100 should not be used.) Destination IP port number [base] If the all ports option is being used for configuration, this value specifies the destination IP port base.
Chapter 3: Connection Methods, Attributes and Configurable Features 21 Table 3.4: Raw TCP Client Connection Method Configurable Items (Continued) Item Idle TCP buffering Description Enables or disables buffering of received serial data while waiting for a TCP connection to be established. When enabled, the most recent 20K bytes of data are held in an internal buffer. Once the connection is established, the buffered serial data is sent to the remote endpoint of the TCP connection.
22 ESP Serial Hub Installer/User Guide Table 3.5: Modem Emulation Connection Method Configurable Items (Continued) Item Description (Used only when Allow Incoming Calls is enabled.) Specifies the port where the ESP hub will listen for incoming connection requests. If the all ports option is being used for configuration, this value specifies the local IP port base. Each port’s actual local IP port number will be the base plus the port number.
Chapter 3: Connection Methods, Attributes and Configurable Features 23 Table 3.5: Modem Emulation Connection Method Configurable Items (Continued) Item Description Specifies whether text or numeric codes will be sent to the serial device in response to modem AT commands and how unknown commands will be handled.
24 ESP Serial Hub Installer/User Guide Modem commands Table 3.6 lists the supported AT modem commands. All other AT commands will be ignored or cause an error, depending on the configured response code and verbose response settings. With the exception of the ? and ATDT commands, multiple commands may be entered on the same line, separated by a space. (If a question mark is entered on a line with other commands, it is interpreted as AT?.
Chapter 3: Connection Methods, Attributes and Configurable Features 25 Table 3.6: Modem Commands (Continued) Command ATS0=n Description Sets the value in register S0, which specifies the number of rings before auto answer. The default value is 1. Specifies whether text or numeric codes will be returned in response to modem AT commands and how unknown commands will be handled.
26 ESP Serial Hub Installer/User Guide The following rules must be followed to enter command mode. • There must be a one-second guard time (no data traffic) before sending the +++. • There must not be a delay longer than one second between each +. • There must be another one-second guard time after the last +. When a port enters command mode, the remote ESP hub will not be aware of this state change.
Chapter 3: Connection Methods, Attributes and Configurable Features 27 which is usually a PC when modem emulation is used). If the TCP connection drops, DTR will be lowered to indicate a Carrier Drop to the attached serial device. Dialout translation When the Allow Outgoing Calls option is enabled, the attached serial device usually specifies the IP address and IP port number of the remote application with the ATDT command.
28 ESP Serial Hub Installer/User Guide Incoming calls When the Allow Incoming Calls option is enabled, the ESP hub will listen on the specified TCP port for connection requests from the network. If another call is active, an incoming connection request will be rejected. If the Monitor DCD option is enabled, the connection will be rejected if the control signal is logically low. The connection will be closed if the inbound control signal changes from logically high to low.
Chapter 3: Connection Methods, Attributes and Configurable Features 29 NOTE: When a port is configured for the serial port redirection connection method, the attributes are specified within the protocol. Therefore, although you may change the attributes, any changes you specify will not take effect. Table 3.10 lists the serial port attributes with their valid and default values. Table 3.
30 ESP Serial Hub Installer/User Guide Table 3.11: Configurable Features (Continued) Feature Description Allow administrative functions via SNMP When enabled, the SNMP interface is used for monitoring and limited configuration of the ESP hub.

61 CHAPTER 7 ESP-Install Program The ESP-Install program may be used to install, modify and remove redirected serial ports and ESP drivers on supported Windows systems. By using a script file, you may streamline the process of installing multiple hubs. The program uses a series of commands (keywords and keyword/value pairs) to identify address information, assign logical COM ports to physical ports and specify other driver-related information.
62 ESP Serial Hub Installer/User Guide You may log additional information with the Debug and Windowdebug commands (see Table 7.1). The ESP hubs do not have to be rebooted for changes to take effect. Creating Installation/Update Command Blocks Installation or update information for an ESP serial hub is delimited using the terms ESP and END. The opening delimiter is ESP on a line by itself - this identifies the start of an installation block for a hub.
Chapter 7: ESP-Install Program 63 For example, in the preceding ESP-2 hub example, physical port 1 was mapped to logical port COM30 and physical port 2 was mapped to logical port COM40. The specified logical (COM) port number must be in the range 0-255 and it must be unique; only one physical port may be assigned to a particular logical (COM) port number. The current mapping may be obtained from the Windows Device Manager on the ESP property page and the Starting COM Port listboxes.
64 ESP Serial Hub Installer/User Guide Commands Table 7.1 describes the commands that may be used in the ESP-Install program. Many of the commands contain detailed driver specifications; contact Technical Support for more information. Syntax conventions Keywords and values are not case sensitive. A command must start on a line by itself. A carriage return marks the end of a command. A comment must be on a line by itself, and must be preceded with a double slash (//).
Chapter 7: ESP-Install Program 65 Table 7.1: ESP-Install Program Commands (Continued) Command Description IP= IP address, in dot notation. This command is required when adding a hub or modifying a hub’s configuration. MAC= MAC address, in dash notation. This command is required when installing an ESP hub that does not yet have an IP address. MASK= Subnet mask, in dot notation.
66 ESP Serial Hub Installer/User Guide The heartbeat rate is 10 seconds and the heartbeat time-out is 80 seconds. All other values (transmit drain, no flush, send modem status, send comms status, no purge and open persist) assume their default values. • Updates (modifies) the driver information for the ESP-4 MI hub at address 10.0.0.117.

Appendices 75 Appendix B: Changing the Serial Port Interface on ESP-2 MI Hubs The factory default interface setting for both ports on an ESP-2 MI serial hub is RS-232. To enable the RS-422 or RS-485 interface for one or both serial ports (or, if you previously enabled one of these interfaces and now want to enable another interface), use the following procedure. You will need a Phillips screwdriver. Proper electrostatic discharge (ESD) protection should be used at all times. Use Figure B.1 as a guide.
76 ESP Serial Hub Installer/User Guide To change the physical interface settings: 1. Place the unplugged ESP-2 MI hub on a flat surface. Use the screwdriver to loosen the two screws on either side of the hub (total of four screws). Remove the screws. Lift the cover up and off the unit. 2. Locate the two ganged headers on the printed circuit board (PCB). Each ganged header contains four columns of five pins. The jumper for each port is ganged and covers two columns.
