Installing a QNX network
4 - 16 • • • Senstar 100 Installation guide
Installing a QNX network
In a Senstar 100 system that contains three or more CUs, you must use a QNX
network to connect the CUs. In a configuration with two CUs, mate link
communication can be via serial cable or network. On a network, you must assign
each computer a unique network node ID ranging from 1 to 255. You can assign
the unique network node ID when you install the QNX operating system.
Senstar-Stellar recommends that the CU number assigned to each computer
should match the node number.
You MUST install a network adapter card in each network
computer. All computers on a network should have the same
type of network card installed.
Knowledge of, and familiarity with, the QNX editor is essential
in the following procedures. Only qualified personnel should
perform the software configuration.
The network should be dedicated exclusively for use by the
Senstar 100 security system.
For a two-CU Ethernet network, a crossover cable is used to
connect the computers. For a network of three to 16 CUs, a
hub is required.
Contact Senstar-Stellar Customer Service for more information
about installing a QNX network.
Setting up an Ethernet QNX network
Perform the following five steps to set up your Ethernet network. Each step is
explained in detail further in this section:
1. Load all of the QNX licenses on each CU.
2. Determine the driver for the network card, and add the Net and Net driver
commands to the
sysinit
file.
3. Create or edit the
netmap
file on all computers in the network.
4. Verify the QNX network status.
5. Set up the Senstar 100 site data to use the network for CU communications.
