NTI SERIMUX SERIES CONSOLE SWITCH

INTRODUCTION

The NTI SERIMUX Console Switch is a serial port router that allows links (or connections) between multiple pairs of RS-232 asynchronous serial ports. The main purpose of the switch is to enable users to manage several serial devices from local or remote locations (using external modems). Devices include routers, DSU's, servers, switches or any other equipment allowing serial operation using RS232 interface. Users can work locally using a VT100 or ANSI serial console or a CPU with a terminal program (i.e. HyperTerminal)) or from remote locations.

Each SERIMUX port has to be configured for serial communication (baud rate, parity, etc) within the specifications of the attached serial device, but the configurations of the two devices linked by the SERIMUX do not need to match. Various parameters (communication speed, hardware and/or software flow control, timeout, etc) can be selected for each SERIMUX port. Devices may be either locally connected or connected through attached modems.

Each SERIMUX port can be configured as either a host or user port. Serial hosts (such as servers, switches etc.) are connected to host ports, while serial user devices (such as a terminal or serial console) are connected to user ports.

The SERIMUX Console Switch supports two operator levels: user and administrator. Users login at user ports and connect to serial devices attached at host ports. The administrator (logged in at any user port) and users with administrative privil eges can see and/or modify various port or user parameters.

INITIAL STARTUP

SERIMUX Quick Start

1. Make sure the SERIMUX is turned OFF.

2. Using the serial device connected to the port labeled "CONSOLE", start the terminal program (e.g. Windows HyperTerminal)

and configure it as follows:

• direct connection (using the appropriate CPU local serial Com port)

• 9600 bps

• 8 bits

• no parity

• 1 stop bit

• no flow control

• ANSI or VT100 terminal mode.

Within the SERIMUX firmware, the "CONSOLE" port is identified as Port 0. For consistency, when Port 0 is mentioned within this manual, it refers to the terminal connected at "CONSOLE".

3. Power ON the SERIMUX. Wait 2 seconds.

4. Press [ Enter ] on the keyboard and wait 3 seconds to be recognized as the default SERIMUX user. The "Accessible host list"

for "User01", logged in at "Port00" will be displayed (see Fig 3). By default, all ports are configured as Host ports and all are accessible.

NOTE: If the user menu does not display re-initialize the SERIMUX following the "Initialize SERIMUX Console Switch to default settings" instructions on page 27.

5. To connect to an attached CPU, enter the number of the port the CPU is connected to and press [Enter].

USING THE SERIMUX CONSOLE SWITCH

The SERIMUX Console Switch is controlled using

• Serial Control- from a "dumb" terminal- locally connected

- through an external modem from a remote location

• Keypad Control (reduced set of commands)

Serial Control

The SERIMUX Console Switch can be easily configured using seri al communications with a keyboard-controlled menu to modify various parameters and options for each port to be connected to a device. The administrator menu can be accessed by the administrator for full feature control, or the user menu, by any user, for more restricted control of port connections.

Keypad Control

The keypad has direct control over basic SERIMUX functions. The keypad can be used to make changes to port connections regardless of any menu control taking place. Command LEDs on the front panel of the SERIMUX Console Switch indicate the status of the switch and what function is being performed. For more on Keypad Control, see page 24.

Serial Control

Using serial control, the SERIMUX supports 2 operator levels, administrator and user, each with separate password protection for security.

administrator name : ADMINISTRATOR or ROOT (all capital letters) administrator password : NTI (default)

FYI: Users may be granted administrative access rights by the administrator.

The administrator and any user with administrative rights can:

• The administrator logs in using an administrator password

• Users login using a password set by the administrator

• view / modify port parameters;

• view / modify user parameters and user access rights to ports;

• disconnect ports, logout users etc.

The administrator name cannot be changed.

To change the administrator password, see page 18.

NTI SERIMUX SERIES CONSOLE SWITCH

ADMINISTRATOR CONTROLS

1. From the user terminal connected to port 0, open the terminal program (configured as described on page 5 under "SE RIMUX

Quick Start").

2. Press [ Enter ] on the keyboard, wait three (3) seconds, and the port will open to the "Accessible host list" for "User01",

logged in at "Port00".

3. Press [Esc] to logout, and [Y] to confirm. A message will be displayed "Disconnecting user now"

4. Press [Spacebar] or [Enter]. A prompt requesting a Username will appear.

below)

NTI SERIMUX SERIES CONSOLE SWITCH

FYI: RE: DscTime ( Disconnect Time) The value shown in the Port list is derived from various sources depending on the type of connection active at the time.

- If a user is logged into a port as just a user, the time shown will be the remaining time based on the user's

timeout setting.

- If a user is logged in with administrative privileges and performing administrative tasks, the time will be based

on the administrator's timeout setting, not based on the user's timeout setting.

- If two ports are connected to each other, and one port has a lower timeout setting than the other, the lower

setting will be shown in the DscTime column and control the connection.

- Press [N] to display port information for ports greater than 16, and then [P] to see the previous page.

Figure 8- Port serial settings menu

Baud rate

Any baud rate (serial speed) between 50 bps - 128Kbps can be selected, (except for port 0, between 300 bps - 115.2 Kbps). To modify the port serial speed (baud rate);

– press [1], – enter the new value or press [T] for a table listing standard baud rates supported, – and press [Enter]. A confirmation will be required for non-standard baud rate values.

Data bit

The data bit number can be 5, 6, 7, 8, (except for port 0: 7 or 8). To modify the data bit number;

– press [2], – then the bit number: 5, 6, 7, 8

Stop Bit

The stop bit number can be 1, 2, 1.5 or 2.5, (except for port 0: 1 or 2 stop bits). To modify the stop bit number;

– press [3], – then [1] or [2] or [A] or [B] to select 1, 2, 1.5 or 2.5 stop bits respectively.

Parity

Parity is set by pressing [4], then [N] for none, [E] for even, or [O] for odd.

Flow Control

The flow control (hand shaking) can be hardware (RTS/CTS or out-band), software (Xon/Xoff or in-band), both or non e. To select the flow control;

– press [5], – then [H] or [S] or [B] or [N] respectively.

Note: If "N" for "none" is selected, data may be lost when sending large (greater than 1000 byte) data packets.

NTI SERIMUX SERIES CONSOLE SWITCH

Note: If a modem is attached to the port, and hardware and/or software flow control is used, the appropriate command may be added to the modem initialization string:

Flow control Command 1 Command 2

None – – RTS/CTS (hardware) &K3 \Q3 Xon/Xoff (software) &K4 \Q1 Both &K6 disable flow control (not necessary) &K0 \Q0

Consult your modem user manual or the modem AT command manual to find the suitable command.

Xon or Xoff Characters

Any non-printable character (ASCII codes between 0 and 31) can be used as flow control Xon or Xoff character. The software flow control is transparent, so the special character is not passed to the connected device. If the Xon and Xoff characters are equal, a toggle mode is automatically used in the software flow control: whenever the special flow control character is received, the current state of flow control is toggled.

To change the Xon or Xoff character;

– press [6], – then [0] for Xoff or [1] for Xon, – enter the new value, – then press [Enter] to save it, [Esc] or [Space] to cancel.

FYI: Press [T] after [6] to display a control codes table.

DTR line behavior

If a modem is not attached to the serial port, the DTR port line behavior on port disconnection can be selected as follows: the DTR line can be held high (active), low (inactive) or pulsed for 0.5 seconds and then he ld high. When a modem is attached to the port, the DTR line will be pulsed on port disconnection, disregarding this parame ter value.

To modify the DTR line behavior on port disconnection;

– press [8], – then [H] or [L] or [P] respectively.

Inter-character delay

An inter-character delay (1 - 60 ms) may be defined, each time a character sequence is transmitted from the port. Using this command, a minimum pause will appear between transmitted characters; for example, certain types of electro-mechanical devices (like teletype equipment) cannot process received characters continuously at their specified baud rate.

To select an inter-character delay;

– press [8], – enter the new value (0 for no delay), – and press [Enter] to save it, [Esc] or [Space] to cancel.

FYI: This parameter is not available for port 0.

Line-break receive or transmit

It is possible to accept the line-break received from a port, and to send it from the connected port. The break condition (when received) is defined as zero data with zero parity and no stop bits.

To allow or not the line-break receive;

– press [9], – then [Y] for allowed, – [Esc] or [Space] to cancel, any other character to deny.

To define the transmitted line-break extra-duration (this is added to the 1-character transmission time);

– press [0], – then enter the new value (1 - 999 ms) or 0 to disable it, – and press [Enter] to save it, [Esc] or [Space] to cancel.

FYI: These parameters are not available for port 0.

User Terse mode

This mode is especially useful when the SERIMUX is directly controlled by external software from a serial console (as a user without administrative privileges), rather than being controlled by a user from a keyboard interface.

Entering short command strings performs functions similar to the user main menu commands. A [CR] – [LF] sequence ends every string. The commands are not echoed; the SERIMUX returns to the serial console a specific answer if the command is successfully accomplished or an error message otherwise.

Terse mode can be used only if the administrator configures a user port to enter into Terse mode at login. If a keyboard-based user logs into a port intended for Terse mode operation, the following image will appear:

Figure 20- User port in Terse mode

From Terse mode, a limited number of functions are possible;
