NTI SERIMUX SERIES CONSOLE SWITCH
INTRODUCTION
The NTI SERIMUX-CS-x Console Switch is a serial port router that allows links (or connections) between multiple pairs of RS-232 asynchronous serial ports. The SERIMUX-CS-x (x=4,8,16,24,or 32) is availa ble with up to 32 serial port connections. 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 via optional Ethernet connection.
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 administrativ e privileges can see and/or modify various port or user parameters.
Option:
• Ethernet Option- includes an Ethernet port for controlling connections using a WEB interface via a Local Area Network
(LAN)- to order, add an “E” to the part number (i.e. SERIMUX-CS-xE)
• Dual Power Option- includes a second power connector for a second ary power supply cable- to order, add a “DP” to
the part number (i.e. SERIMUX-CS-xDP)

INITIAL STARTUP
SERIMUX Quick Start
The following instruction will enable the user to quickly make port connections using a terminal connected to the “CONSOLE” port. For instruction to make quick connection using the optional Ethernet port and Web Interface, see page 35.
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. 6). By default, all ports are configured as Host ports and all are accessible.
NOTE: If the user menu does not display reset the SERIMUX following the "Reset SERIMUX Console Switch to default settings" instructions on page 34.
5. To connect to an attached CPU, enter the number of the port the CPU is connected to and press [Enter].

NTI SERIMUX SERIES CONSOLE SWITCH
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)
• Web Interface- from optional Ethernet connection to a LAN
Serial Control
The SERIMUX Console Switch can be easily configured using serial communications from either a locally-connected “dumb” terminal or from a terminal remotely connected through a modem. Using a keyboard-controlled menu, the user can modify various parameters and options for each port. The administrator menu can be accessed by the admi nistrator 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 31.
Note: The keypad will only work after first entering the assigned PIN number. See page 31 for more info.
The default keypad PIN number is 9999 (or 4444 for SERIMUX-CS-4).
Web Interface
With an Ethernet connection to a LAN, the user can remotely control SERIMUX port configuration and connections. 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. For more on Web Interface control, see page 35.
SERIAL CONTROL- ADMINISTRATOR
Using serial control, the SERIMUX supports 2 operator levels, administrator and user, each with separate pass word prot ection for security.
• The administrator logs in using an administrator password
administrator name : administrator or root (all lowercase letters) administrator password : nti (all lowercase letters)
FYI: Users may be granted administrative access rights by the administrator.
The administrator and any user with administrative rights can:
• 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 20.

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 co n nected 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.

Port serial settings
From the "Port settings" menu, press [5] to display the "Port serial settings" menu. Using this menu, the administrator can adjust the serial settings of each port, or copy the current port serial settings and paste them to another port or to all ports.
Figure 11- 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, (except for port 0: 1 or 2 stop bits). To modify the stop bit number;
– press [3], – then [1] or [2] or [A] to select 1, 2, or 1.5 stop bits respectively.
Note: When Data bit is 5/6 the stop bit can be 1 or 1.5, otherwise it can be 1 or 2
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 none. 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.
14
Page 20
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 comman d.
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 (see page 19). If a keyboard-based user logs into a port intended for Terse mode operation, the following image will appear:

TROUBLESHOOTING
If the Console Switch is not working properly, consider the suggestions below to see if a solution can be found.
Problem Cause Solution
No Front Panel LEDs are illuminated No power to SERIMUX Check all power connections SERIMUX is not working properly
• Poor Connections
• Port not configured correctly
• Ports not initialized
Cannot Connect to port/device
• Port settings not correct
• Wrong cable adapter used
• Connections are loose
Commands entered from front panel
Buttons are being pressed too rapidly 1) Make sure the Keypad PIN is
keypad are not accepted
SERIMUX will not accept username or password
Usernames and passwords are case
sensitive Cannot access user menu on a port Port is configured as host port Configure port as user port. (pg. 10) I cannot access the View Port Data Buffer
Only the ROOT user can access this (see
page 14) If the passwords or other important parameters are not available, the SERIMUX Console Switch can be re-initialized to the default settings (see "Initialize SERIMUX Console Switch to default settings" on page 34).
Caution: During initialization, the customer modified parameter values will be replaced with the factory default values; all ports will be placed in buffer mode; all passwords will be erased.
If the suggestions above have been tried and the NTI Console Switch is still not functioning properly, a solution to the problem may be found on our website at http://www.networktechinc.com in our FAQ (Frequently Asked Questions) section, or, please call us directly at (800) 742-8324 (800-RGB-TECH) in the US & Canada or (330) 562-7070 (Worldwide) and we’ll be happy to assist in any way we can.
• Verify that all cables are securely connected
• Verify that the port configuration matches that of the device connected
• Power-up the CPUs first, then the SERIMUX
• Verify proper communication settings (pg 8)
• Verify that adapter is one specified in Appendix C.
• Verify that all cable connections are secure
entered properly.
2) Press the “Enter” key before typing
the PIN to discard the previous entry.
3) Try the PIN again but slow down
the button sequence- approx 1/2 sec between each press.
Verify characters used and enter again.
