Fault finding

(down). (If you change the position of this switch you must remove
the power from the Controller and then power up again.) If the switch
position is correct and the LEDs still do not give the correct flashes,
the RS485 connections are probably faulty - check the wiring.
RS232 connections between PC and Comms module or
Controller
When you connect the PC and run the System Manager Software, a
message at the bottom of the computer screen tells you if the system
is on line or off line. If it says off line, check the RS232 connections.
Make sure that RTS and CTS are connected correctly and that TXD
and RXD are crossed, see the diagram in the chapter on the “4101
Controller” or the “Comms module”. If the computer is connected
directly to a Controller, check that switch 4 of the DIL switch labelled
SW3 on its motherboard is in the “ON” position (up). (If you change
the position of this switch you must remove the power from the
Controller and then power up again.)
Entering a site code
You cannot get the system to read cards until you have entered a site
code in the System Manager program. Click on the Tools page, then
click on the Admin Setup button. In the column labelled Number,
type your site code in the row labelled 0, then click on the OK button.
Downloading the data from the Software
When you have got the comms working you can download the card
and reader configuration from the PC to the Controllers. If the PC is
on line, this is done automatically when you enter the data into the
Operator Software. To be certain that the data reaches the
Controllers, you can download the whole database manually using
the Reconfigure System button on the Tools page of the System
Manager Software. If the system still does not work, read the next
sections.
Checking the reader modules
Each Cotag reader has a pair of amber LEDs on the module. The left
hand LED of each pair should be flashing, showing that the
Controller is polling the reader.
Reader not being polled
If any of the readers are not being polled, you must return to the
Operator Software and check the Access Point records. Use the
Update System List button on System Manager’s Configuration
page to see what the Software thinks is connected and configured.
