4101-2 Controller Installation Handbook

Setting up the Controller
On a system comprising only one Controller:
• Set switch 4 of SW3 up, leave switch 3 down.
• Set the RS232 baud rate on JU1. This must be set to the same
value as the computer. It is normally in the 9600 position.
On a system comprising two Controllers:
• On the Controller connected to the computer (the master
Controller), set switches 3 and 4 of SW3 up.
• On the Controller not connected to the computer (the slave
Controller), set switches 3 and 4 of SW3 down.
• On the Controller not connected to the computer (the slave
Controller), set the rotary address switches SW1 and SW2 to
01.
• On the master Controller, set the RS232 baud rate on JU1.
This must be set to the same value as the computer. It is
normally in the 9600 position.
On a system comprising more than two Controllers:
• Set switches 3 and 4 of SW3 down.
• Set the address of the Controller on the two rotary switches
SW1 and SW2. The address can be any number from 00 to 99,
but must be different from the address of any other Controller
on the same branch.
Installing a system - noting the addresses of
readers, inputs and outputs
When you install a system, make a note of the Controller/Module
address for each reader and its location in the building. This
information is necessary when you set up the Access Points database
in the Software. If someone else is setting up the Software then make
sure they have the list of addresses and locations for all Access
Points in the system.
If you install one or more 4253 Input/Output modules, you must
note the address and function of each input and output. Again, if
someone else is setting up the Software then make sure they have the
list of addresses and functions for all inputs and outputs in the
system.
