SNIB2 Configuration Guide

Each connected controller must have its own SNIB2 or SNIB board installed. The
SNIB2 provides RS-485, RS-232, and 10/100BaseT Ethernet ports. The SNIB2
supports the XNET2 protocol.

XNET2 is only supported by Velocity version 2.6 with Service Pack 2 or
higher.
Physically, the SNIB2 board differs from the original SNIB in three obvious respects.
The SNIB2 has:
O
O
O

three switch banks (SW1, SW2, and SW3)
an Ethernet RJ-45 connector with its accompanying daughterboard
three pairs of status LEDs (see page 19)

With the SNIB2 board, a host PC running Velocity can program, monitor, and control up
to 63 controllers with NET*MUX4 (as shown in the example below), or up to 16
without NET*MUX4. Each connected controller must have its own SNIB2 or SNIB
board installed. The SNIB2 provides a downstream/multi-drop RS-485 port as well as
an upstream 10/100 Mbps Ethernet port and an RS-232 port for direct host
connections (not dial-up).

Each of these features is explained below.
AES Encryption
The SNIB2 employs AES-Rijndael asymmetric 128-bit block data encryption.

The National Institute of Standards and Technology (NIST) has awarded
the SNIB2 AES Certificate #280.

Ethernet Connectivity
A standard RJ-45 Ethernet port is included on the SNIB2. This enables the connected
controller installed with a SNIB2 to communicate with the server using TCP/IP over
10BaseT or 100BaseT Ethernet networks. This eliminates the need for external device
servers for LAN connectivity.

SUPP009-0907

XBox Functionality
The SNIB2 also incorporates full XBox gateway functionality, thereby eliminating the
need for an XBox. This enables the SNIB2 to function as a gateway for up to 63
controllers (with inclusion of the NET*MUX4), and provides the ability to globalize
certain features.
Globalizing is the task of connecting two or more controllers in order to share credential
user management and control zone information amongst all connected controllers.
Globalization can only be performed within a local XBox node. One SNIB2 acting as an
XBox cannot talk to and share information with another XBox or another master SNIB2.
Higher Serial Communication Speeds
Communications between multidropped SNIB2s are now supported at speeds up to
115,200 bps with Cat5/Cat6 cable.
When using one or more NET*MUX4s, the maximum SNIB2 speed is limited to 9600
bps. When combining SNIBs and SNIB2s, the maximum speed is limited to the lower
SNIB speed – that is, the lowest speed that all connected devices have in common.
Communications become less robust as baud rates increase, wire gauge decreases,
and distances increase. Most tables in the DIGI*TRAC Design and Installation Guide for
wire gauge and distance are based on 9600 bps.
At higher baud rates, maximum distances are decreased and minimum wire gauge is
increased. It may not be possible to implement the higher baud rates supported by the
SNIB2 if you have long wire runs or small wire gauges.

In order to use the SNIB2, your controller must be running
CCM 7.3.08 or higher; use Vn. 7.4.00 or higher if your
computer has Velocity 3.0. To check your current version
number, refer to “Checking CCM and BIOS Version” on page
22.
You can install the SNIB2 board in any Hirsch DIGI*TRAC
controller except the M1N.

= this cable segment swaps the RX± and TX± wires. See page 8 for details.

This enables communication between the controller with the master SNIB2 and host
PC at 10/100BaseT. Speeds between the master SNIB2 and other connected
downstream SNIB2s range up to 115200 bps when using Cat5/Cat6 cable. Speeds
between a master SNIB2 and downstream SNIBs are limited by the top speed of the
older SNIBs (38400 bps).
Higher baud rates are also more dependent on the number of twists per foot, so
capacitance specifications must be strictly followed: total wire run per port is not to
exceed 100,000 pf per foot.
Before the Velocity server can communicate over Ethernet with a SNIB2, you must first
configure the SNIB2 through Velocity. For more on this, refer to “Configuring a Master
SNIB2 on the Same Subnet” starting on page 13.
Whenever an Ethernet connection is employed between the host and the SNIB2,
Velocity views the SNIB2 as an XNET port since the SNIB2 includes XBox functionality.
The host communicates with the Ethernet-connected SNIB2 using AES-encrypted
XNET 2.

Configuration Options

SUPP009-0907

Controller-to-controller speeds range from 9600 to 115200 bps. For each string of
controllers, the first (master) SNIB2 with the Ethernet connection must be assigned the
same address as the XBox port.
For more on this, refer to “Configuring a Master SNIB2 on the Same Subnet” starting on
page 13.

When the host is connected to a SNIB2 using Ethernet, Velocity views the
first (master) SNIB2 as both a DIGI*TRAC controller and an XBox residing
on an XNET port. Subsequent multidropped controllers in the sequence
do not appear as XBox controllers.
You can also use the SNIB2 with the NET*MUX4. The NET*MUX4 consists of a single
input for either RS-232 or RS-485 and four outputs to which a series of controllers or
additional NET*MUX4s can be wired as shown in the following illustration:

SNIB2 Configuration Guide

Installing the SNIB2
To install the SNIB2:
1.

Download CCM 7.3.08 or later firmware to the required controllers.
For instructions on doing this, refer to “Download Firmware Revision” in Velocity
help or the Velocity Administrator’s Guide.

Make sure each controller in the sequence shows the CCM version as 7.3.08 or
later, and the BIOS as Version 7.2.19 or later.
For more on checking this, refer to “Checking CCM and BIOS Version” on page 22.
If these version numbers do not appear, replace the controller’s CCM.

3.
Hint

Pull the original SNIBs from each required controller.
We recommend removing the SNIBs controller-by-controller to ensure that each
SNIB2 comes online successfully.

Follow the instructions in Chapter 7 of the DIGI*TRAC Design & Installation Guide.
4.

Run the required network cable to the controller(s) with the master SNIB2s.
The Ethernet cable you are connecting to each master SNIB2 should be connected
to the Velocity host through a hub or switch.

Run RS-485 cable downstream from the master SNIB2.
The run between the master SNIB2 and the second SNIB2 should be wired
according to the instructions in “Cabling the SNIB2” starting on page 8.

Set the DIP switches on each SNIB2.
In general, do this:

Install the new SNIB2s into their controllers.
Follow the instructions in Chapter 7 of the DIGI*TRAC Design & Installation Guide.
Handle the SNIB2 with care. The board is very sensitive to
static discharges. Observe the normal anti-static precautions
by using grounded wrist straps and anti-static devices when
installing the board.

Plug the RJ-45 connector from the cable into the Ethernet connector on the
SNIB2.
9. Connect the RS-485 cables to their respective SNIB2.
10. Reconnect and power up the controllers.
11. At the host, open Velocity and configure the new SNIB2s using the instructions in
“Configuring a Master SNIB2 on the Same Subnet” starting on page 13.

Installing the SNIB2

SNIB2 Configuration Guide

Cabling the SNIB2
The cable linking the first controller (master) to the second (subordinate) in a

At 9600 baud, the maximum allowed cable run between controllers is shown in the
following table:
Connection

Maximum Distance

Total Max. Run from Master SNIB2 to Last
Downstream SNIB2

4000 feet (1,220 m.)

In general, communications become less robust as baud rates increase, wire gauge
decreases, and distances increase. For this reason, it may not be possible to implement
the higher baud rates supported by the SNIB2 if you have long wire runs or small wire
gauges.
Higher baud rates are also more dependent on the number of twists per foot, so
capacitance specifications must be strictly adhered to: total wire run per port is not to
exceed 100,000 pf per foot.
Hint

We recommend using Cat5/Cat6 cable for your cable runs. Use 1 pair for the RX
pair, 1 pair for the TX pair, and 1 conductor or pair for the ground connection.

Installing the SNIB2

SUPP009-0907

Setting Up the SNIB2
The SNIB2 includes three DIP switch banks. The first bank (SW1) and second bank
(SW2) have four DIP switches each. The third bank (SW3) possesses eight DIP
switches.
Switch Bank 1
(SW1)

SNIB2s can be used throughout a multidrop run; however, you must specify whether a
specific SNIB2 is connected to a controller that is in the beginning, middle, or at the
end of a run.
To do this, set S1-S4 on switch bank SW1 to all ON or all OFF in this way:
S1-S4

Switch Bank 2
(SW2)

OFF

This SNIB2 is in the middle of a multidrop sequence.

This SNIB2 is either first (master) or last (termination) in
the multidrop sequence.

The second switch bank at SW2 has 4 switches which configure such properties as the
type of XNET protocol you are using and the SNIB2’s location in the multidrop run.
S1

OFF

The SNIB2 communicates with the host PC in XNET 2
using the encryption keys stored in memory.

Return the encryption keys to their default settings. If this
switch is set when the SNIB2 powers up or reboots after
a firmware upgrade, the keys reset.
Note: This switch should be turned off after the LED patterns
begin to light. See the SNIB2 Troubleshooting Guide for
details.

If this is the master SNIB2, you must also ‘Reset
Encryption’ on the Velocity Port settings. All downstream
units must have their encryption keys reset as well. If this
is a downstream unit, the master SNIB2 automatically
detects that the keys have been reset.

Baud rates only apply to the SNIB2's RS-485 and RS-232 ports. The SNIB2's Ethernet
port is used for host-to-controller connections and runs at 10/100 BaseT speeds. All
SNIBs/SNIB2s in an RS-485 multi-drop sequence must be set to the same speed, and
if connected to a host PC using RS-232 direct connection, the same speed must also
be used. For example, if one SNIB2 in the sequence is set to 9600, all other SNIBs and
SNIB2s (and the RS-232 host connection, if used) must be set to the same baud rate.

SNIB2 Configuration Guide

Deploying the SNIB2
Each master SNIB2 (Velocity port) must be assigned a unique IP address in order to
communicate with Velocity on the host PC. Depending on the network location of the
master SNIB2, this is accomplished in one of two ways:
O

If the SNIB2 is located within the same subnet as the host PC, then you can use
Velocity to assign the IP address. For more on this, refer to “Configuring a Master
SNIB2 on the Same Subnet” starting on page 13.
If the master SNIB2 is located outside the host PC’s subnet, you must use the
SNIB2 Configuration Utility. For more on this, refer to “Configuring a Master SNIB2
in a Different Subnet” starting on page 15.

What is a subnet? Put simply, a subnet is any group of PCs and other devices, such as
printers and scanners, connected by network cable to a network router. Anything
behind the router is considered part of the subnet. Anything beyond this router is not
part of the subnet.

In the preceding illustration, the master SNIB2 and controller labeled 1 is located in the
same subnet as the host PC (Subnet A). This SNIB2 can therefore be configured using
Velocity; however, the master SNIB2 and controller labeled 2 is located behind a
different router, in a different subnet (Subnet B), and must be configured using the
SNIB2 Configuration Utility.
Any number of computers and devices can be behind a single router, but for reasons
of security and speed, a company network often incorporates many routers. It isn’t
uncommon to find that each department within a company has its own router. Routers
not only find the quickest way to ferry packets of information between two points, but
also could serve as a rudimentary firewall against potential intrusion.

Installing the SNIB2

SUPP009-0907

Configuring a Master SNIB2 on the Same Subnet
When a master SNIB2 is connected via Ethernet to the host PC sharing the same
subnet, configure and assign a new IP address through the Velocity port properties
dialog box.
To do this:
1.

At the System Tree window, click and expand the DIGI*TRAC Configuration system
folder,
.
Three port folders are currently available: SNET, XNET, or Dial-Up.

Expand the XNET Port folder.
When the Velocity host is connected to a SNIB2 via Ethernet, it treats it as an XNET
port.

Double click Add New XNET Port in the Components window.
The Port Properties dialog box appears like this:

Click to select the TCP/IP radio button.
The dialog box changes to show the ‘IP Address’, ‘Port’, and ‘Max Attempts’ fields.

Check the XNET 2 Protocol checkbox to indicate this port is using encrypted
XNET 2 protocol.

Notice when you check this box...
... this Search button is activated.

Click the Search button.
Velocity searches on the subnet for all SNIB2s that Velocity is not using.

If a SNIB2 is currently logged on, the search feature will not detect it.
A dialog box appears listing all new SNIB2s like the following example:

Installing the SNIB2

SNIB2 Configuration Guide

New SNIB2 detected

Since all SNIB2
MAC addresses
start with the
same six digits
(00:90:C2), the
label on the
SNIB2 only lists
the last six digits.

Drag the slide bar over to
the right to see the MAC
Address column. While a
newly detected SNIB2
does not have an
assigned IP address, it
always has a unique MAC
address.

While a newly-detected SNIB2 does not possess an IP address, port number, or
name, it should have a unique MAC address. To see this MAC address, drag the
slide bar at the bottom of the dialog box to the right. The MAC address for each
SNIB2 is printed on a white label located on the left side of the SNIB2’s
daughterboard. This label contains both a barcode and a six-digit number. This
number is the last six digits of the MAC address.
7.

From this list, double click the SNIB2 entry you want to configure.
The SNIB2 Configuration dialog box appears like this example:

8.
9.

In the 'Name' field, enter the name you want to assign to the SNIB2.
At the ‘IP Address’ field, enter the IP address for the SNIB2 connected to this
Velocity PC.
In version 5.95 and later, all SNIB2s will have a factory default IP address in the
format 10.x.y.z where the variables are supplied from a hash of the MAC address.
For versions earlier than this, you must enter the required IP address.

10. At the 'Port' field, enter the correct port number.
All network ports possess an address used to identify the SNIB2’s physical port
address. The default Velocity port is 10001.

Consult your system administrator for the correct values for both the IP
and port address.
11. Click OK. The Searching screen reappears.
12. Click OK.
The Port Properties screen reappears with the Name, IP Address, and IP Port fields
populated.
13. At the 'Max retry attempts' field, specify the maximum number of retries this PC
will attempt. Increment or decrement the value using the counter buttons.
If you get port errors, increase this number.
14. Check the 'Enable this Port' box if this port is currently active. Clear this box if the
port is not currently active.
15. If required, click the Advanced button to access the Advanced Settings dialog box
to specify additional options for this port.

Installing the SNIB2

SUPP009-0907

16. When you're finished, click OK.
The new SNIB2 port appears in the Components window.

If you ever need to reassign an IP address, repeat this procedure.

Configuring a Master SNIB2 in a Different Subnet
To connect a master SNIB2 via Ethernet to a host PC residing outside the host PC’s
subnet, configure and assign a new IP address for the master SNIB2 on its own subnet
using the SNIB2 Configuration Utility as described in this section.
To configure a master SNIB2 using the SNIB2 Configuration Utility:
1.

If you haven’t already, install the SNIB2 Configuration Utility in a PC in the same
subnet as the master SNIB2 you want to configure. To do this:
a. Insert the Velocity CD in your CD drive or go to the \Velocity folder.
b. Using Windows Explorer, navigate to the \SNIB2 folder. The file
SNIB2CONFIG.EXE should be located here.
Double click SNIB2CONFIG.EXE.
The SNIB2 Configuration Utility appears like this example:

Select one of these radio buttons:
Search for all devices

Select this option to search for all SNIB2s on this
subnet.
Note: If a SNIB2 is currently logged on, the utility will not
detect it.

Offline devices only

Select this option to search only for SNIB2s that are
currently offline. It automatically eliminates all
SNIB2s that are already configured for this subnet.
This is the default selection.

Search this IP Address Select this option if you know the address of the
SNIB2 you are programming, then enter the SNIB2s
current IP address in the field to the right of this
radio button.
Use this option to change the IP or port address of a
previously-configured SNIB2.
4.

Click the Search for SNIB2 button.
The utility scans the network within the current subnet and returns a list of all
devices meeting the criterion specified by the radio button.

Installing the SNIB2

SNIB2 Configuration Guide

Click the ‘Devices’ pick list to display all devices currently detected by the utility, like
the following example:

All detected
devices

The MAC address
has the prefix id=

6.
Since all SNIB2
MAC addresses
start with the
same six digits
(00:90:C2), the
label on the
SNIB2 only lists
the last six digits.

Select the correct SNIB2.
You can identify which SNIB2 you need, by its MAC address (id=). The MAC
address for each SNIB2 is printed on a white label located on the left side of the
SNIB2’s daughterboard. This label contains both a barcode and a six-digit number.
This number is the second half of the MAC address.

Select the Get Configuration From Device button.
A list of variables specific to this SNIB2 appear in the ‘Variable Name’ window.
The three options used for SNIB2 configuration are: Device_IP_Address,
Device_Port, and Device_Hostname as shown in the following example:

These 3 options are available.

From the ‘Variable Name’ pick list, select Device_IP_Address.
A screen like this example appears:

In the ‘Value’ field, enter the IP address you require for this SNIB2.
A screen like this example appears:

Consult your IT or Security Administrator for the proper address.
10. From the ‘Variable Name’ pick list, select Device_Port.

11. At the ‘Value’ field, enter a port address for this SNIB2.
All network ports possess an address used to identify the SNIB2’s physical port
address. The default Velocity port is 10001.
12. From the ‘Variable Name’ pick list, select Device_Hostname.
13. At the ‘Value’ field, enter a name for this SNIB2.
14. Click the Send Configuration to Device button to send the information to the
SNIB2.
15. Click the Search for SNIB2 button again to verify that the SNIB2 has correctly
received the information.
Make sure to write down the address, port, and host name you assigned for each
SNIB2. These values are required when you configure the SNIB2 in Velocity.
Hint

If there are a lot of master SNIB2s to configure remotely, we recommend using a
dedicated portable computer with SNIB2CONF already installed. This should
enable the installer to do the job more rapidly. But be careful: make sure you are
on-site when you do this. A SNIB2 does not retain its IP address for more than 5
minutes after being unplugged from a controller. If you are planning to program
several SNIB2s from a controller then move them to a remote site, you probably
won’t have time before the IP address in each SNIB2 is irrevocably lost.

Once the installer has assigned the remote master SNIB2 an IP address and port, use
Velocity on the host PC to identify it to the system. To do this:
1.

Create a new XNET port as specified in Steps 1–5 of “Configuring a Master SNIB2
on the Same Subnet” starting on page 13.
Do not use the Search button. This only works for finding SNIB2s that are
currently residing on the host PC’s subnet.

2.
3.
4.
5.
6.

In the 'Name' field, enter the name you assigned to the SNIB2 using the SNIB2
Configuration Utility (Device_Hostname).
At the ‘IP Address’ field, enter the IP address you assigned to this device using the
SNIB2 Configuration Utility (Device_IP_Address).
At the 'Port' field, enter the port number you assigned to this device using the
utility (Device_Port). The default value is 10001.
Make sure the ‘Enable this Port’ box is checked.
Click OK.

This enables Velocity to find and monitor the remote SNIB2.

Resetting SNIB2 Encryption Keys
Once Velocity creates the encryption keys required for secure Host-to-SNIB2
communication, it continues to use those keys. If, for whatever reason, you need to
change these keys, there are several ways to do it.

Several of these techniques reset not only the SNIB2 encryption keys but
also the controller.
Set SW2-1 to:
SW2
ON

1
2
3
4

OFF

Procedures/Results
• Cycle power on controller. SNIB2 retains encryption keys.
Controller retains setups.
• Press the blue button on the controller until it resets. SNIB2
retains encryption keys. Controller loses setups.
• Download SNIB2 firmware through Velocity. SNIB2 retains
encryption keys. Controller retains setups.

• Cycle power on controller. SNIB2 resets encryption keys.
Controller retains setups.
• Press the blue button on the controller until it resets. SNIB2
resets encryption keys. Controller loses setups.
• Download SNIB2 firmware through Velocity. SNIB2 resets
encryption keys. Controller retains setups.

OFF or ON

Download CCM firmware through Velocity. SNIB2 retains
encryption keys. Controller retains setups.

Once you have reset the encryption key to its default value (set SW2-1 to ON, recycle
controller power, then reset SW2-1 to OFF), you must assign a new key so that Velocity
and the master SNIB2 can talk to each other. To do this:
1.
2.

From the Velocity Administrator system tree, click and expand the DIGI*TRAC
Configuration system folder until the master SNIB2 port you require appears.
Right click on the SNIB2 port and select Properties.
The Port Properties dialog box appears. The master SNIB2 Properties should look
like this example:

Check this box to reset the
SNIB2 encryption keys.

Check the ‘Reset Encryption’ box and click OK.

This resets and syncs the encryption key at host SNIB2.

Controller and SNIB2 LED Diagnostics
The SNIB2 has three pairs of LEDs that show you how the SNIB2 is communicating
with the host PC.

Special Light Patterns: Start Up
This consists of the following light patterns during start up.
First comes the Lamp Test.

Power-up might include the first two patterns. If you’ve just reflashed the SNIB2, the
sequence starts with the ones in the box.
This pattern is followed by:

This is the SNIB2/CCM Synchronization. This pattern repeats until the CCM and
SNIB2 are synchronized. This light pattern should not persist longer than four minutes if
there are no memory expansion boards on the controller.

Normal Operation
This table illustrates the various light patterns displayed during normal operation for
both the master and subordinate SNIB2s:
Master or Subordinate
Ordinary communication between master and subordinates.
Lights may blink or stay lit during heavy data transfers. They will
go out every 4 seconds during idle or low-traffic periods; this is
normal, indicating the master is hunting for new addresses, such
as newly-added controllers or controllers that went offline and are
expected back online.

If this stays lit and doesn’t go out every 4 seconds, that means
there’s a lot of data going to or coming from some other

won’t come online until the data traffic decreases. This pattern
may also alternate with occasional red or green P3 flashes.

The NET green LED is on; the NET red LED blinks intermittently
depending on the amount of data being received from the host.

AC

Neither NET LED is blinking or only the NET green LED is on. In
either case, the master SNIB2 is not communicating with the
host.

This indicates the SNIB2 is working properly.
Note: The exact NET LED behavior depends on the controller version.

Check both your Ethernet connection and your Velocity port
configuration.

Checking CCM and BIOS Version
Before you can flash your current CCM to 7.3.08 or higher, you must first check the
CCM BIOS level. In order for the 7.3.08 or higher flash update to work properly, you
must be running a CCM with a CCM BIOS level of 7.1.20 or higher.

If you are running a CCM with CCM BIOS 7.1.8, you will need to
replace your CCM, since the flash will not work properly and the
controller may not reboot if powered off.
The CCM BIOS level currently shipping is 7.3.17.
To determine the CCM BIOS of your controllers, use one of two methods.

Method 1

The simplest method is to check the General page of Controller Properties for the
specific controller in this way:
1.
2.

Expand the Velocity system tree until the selected controller appears.
Right click the selected controller and select Properties.
The CCM Firmware and CCM BIOS versions appear in the ‘Firmware Revision’
section of the General page like this example:

Notice that the Update buttons for
both CCM Firmware and SNIB2
Firmware are located on this page.
For more on using these buttons,
refer to Velocity Help.

BIOS and CCM
version number

Method 2

The second method requires use of Velocity’s Diagnostic Window. To do this:
1.

From Velocity menu tool bar, select Help > Diagnostic Window.
The Diagnostic Window appears.

At the top of the window, click the red Diagnostic Stream button.
The button turns green.

3.
4.

From the ‘Controller’ pick list, select the appropriate controller.
From the ‘Diagnostics Command’ pick list, select 1 - Date, Time, Version
Number, then click the
button to the right of this pick list.
The controller displays system information in the bottom pane. Look for the
following information and determine the BIOS level of your CCM:
1:24:40 PM 001:001:001 SNET Message 110 Current Date and Time is Thu
28-Oct-2004 13:25:19 (Regular)
1:24:40 PM 001:001:001 SNET Message 139 Device Info Device Type 3 M2
1:24:40 PM . ROM Sig. ffffffffffffffffx BIOS=7.2.19 Firmware
Date=20041027 Vn. 7.3.08

In this example, we ran CCM BIOS 7.2.19. (The Firmware version number may be
different from the BIOS number. Only determine the BIOS Level.)
5.

If you are running BIOS Level 7.1.20 or higher you can use Velocity to flash your
CCM with 7.3.08 or higher.

You can find the latest CCM firmware in your ...\Velocity\Firmware subfolder.
