SNIB2 Configuration Guide
The SNIB2 is a high-security encryption Secure Network Interface Board. An example of
the SNIB2 is shown below:
The SNIB2 is a controller-resident communication board that enables a host PC
running Velocity 2.6 SP2 or higher to program, monitor, and control up to 63
SNIB2-resident controllers per SNIB2 Ethernet port. A NET*MUX4 is required whenever
there are more than 16 controllers. Additional NET*MUX4s may be required to ensure
that there are never more than 16 controllers per port.

SNIB2 Configuration Guide
2
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:
Othree switch banks (SW1, SW2, and SW3)
Oan Ethernet RJ-45 connector with its accompanying daughterboard
Othree 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).
The SNIB2 provides these functional advantages over the original SNIB:
OAES encryption
OEthernet connectivity (if required)
OXBox functionality
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.

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.

SNIB2 Configuration Guide
4Configuration Options
Configuration Options
The SNIB2’s Ethernet port provides high-speed TCP/IP communication over an
Ethernet network between the host computer and the controller.
In a multiple controller sequence, the configuration can look like this example:
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 5
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:
If required, you can add a second level of NET*MUX4s to create additional controller
runs; however, Hirsch does not support more than two levels of NET*MUX4s.
NET*MUX4 speeds are dictated by wire gauge and distance. We
recommend using Cat5/Cat6 cable.

6Installing the SNIB2
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.
2. 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. Pull the original SNIBs from each required controller.
Hint 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.
5. 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.
6. Set the DIP switches on each SNIB2.
In general, do this:

8Installing the SNIB2
Cabling the SNIB2
The cable linking the first controller (master) to the second (subordinate) in a
multidropped RS-485 series must cross the RX± and TX± wires in this manner:
If more than two controllers are connected in the series, the wiring would look like this:
At 9600 baud, the maximum allowed cable run between controllers is shown in the
following table:
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.

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.
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:
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.
Switch bank SW3 is used to specify the SNIB2 speed (S1-S2) and the SNIB2 address
(S3-S8). DIP switch settings for this are:
This controls the baud rate for the RS-485 multi-drop line and the RS-232 connection.
57600 and 115200 bps are only available if your RS-485 cables are made from
Cat5/Cat6 data grade wire. These speeds are not recommended for installations using:
S1-S4 OFF This SNIB2 is in the middle of a multidrop sequence.
ON This SNIB2 is either first (master) or last (termination) in
the multidrop sequence.
S1 OFF The SNIB2 communicates with the host PC in XNET 2
using the encryption keys stored in memory.
ON 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.
S2-S3 OFF Reserved.
S4 OFF Indicates this SNIB2 is NOT first in the multidrop
sequence, or you only have one controller.
ON Indicates this SNIB2 is first in the sequence (master) and
is connected to the host via Ethernet or direct RS-232
connection (not dial-up). This SNIB2 controls polling.

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
12 Installing the SNIB2
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:
OIf 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.
OIf 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.

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.
2. Expand the XNET Port folder.
When the Velocity host is connected to a SNIB2 via Ethernet, it treats it as an XNET
port.
3. Double click Add New XNET Port in the Components window.
The Port Properties dialog box appears like this:
4. Click to select the TCP/IP radio button.
The dialog box changes to show the ‘IP Address’, ‘Port’, and ‘Max Attempts’ fields.
5. Check the XNET 2 Protocol checkbox to indicate this port is using encrypted
XNET 2 protocol.
6. 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:
Notice when you check this box...
... this Search button is activated.

14 Installing the SNIB2
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. In the 'Name' field, enter the name you want to assign to the SNIB2.
9. 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.
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.
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.
