ATS Designers Guide 49

The ATS1801 interface has two RS232 ports that enable communications with a

computer and printer or a digital video recorder. The connection isn’t time-limited and the

connection security is ensured by a 10-digit security code that must be the same in the

control panel, and the PC to activate the connection.

3.3.3 Increasing the range between the control panel and PC.

Often the control panel is located a considerable distance from the PC on which the

system management program is running. Therefore the issue is vital for system design,

and it is necessary to predict what elements are required to connect the control panel to

the monitoring computer.

3.3.3.1 RS485

To increase the connection distance between the Advisor MASTER control panel, and

the PC with the managing software the system bus accessories can be used. By

converting the RS232 into RS485, we can achieve a maximum distance of 1500m. Bigger

distances can be achieved by following the steps described above in section 3.1.3

paragraph Increasing the system bus range

3.3.3.2 Modem and a dedicated leased line

Another solution is to use a leased phone line. Modems need to be installed on the

control panel and computer side of the line.

3.3.3.3 TCP/IP

By using RS232 – TCP/IP converters, the Ethernet network can be used to communicate

with the control panel. Although the bandwidth used by the Advisor MASTER system is

small the security system communications need to be made using separate wiring. This is

dictated by the need to protect the system from access by unauthorised persons.
