6.5 COMMUNICATION LINKS
Communication Modes available to the SitePro Controller are:
1. The SitePro Controller can communicate with other devices such as the
Communication System Director (CSD), IMC, and RF Station. Communication
occurs primarily through an RS-232C serial interface normally operating at 38.4
kilobaud. For a SitePro Controller interfacing with a Site Interface Module (SIM)
this is set to 38.4 kilobaud.
2. The SitePro Controller can communicate with other SitePro Controllers in the normal
mode of operation, over a Backup Serial Link (BSL). The link uses 0-13.8 VDC
levels and operates at 38.4 kilobaud and is ordinarily used in a bus configuration. For
a SitePro Controller interfacing with a SIM this is set to 38.4 kilobaud.
3. A timing signal called the Frame Sync Line (FSL) helps arbitrate the use of the BSL
serial bus. The FSL is also used for timing purposes. In the station configuration, FSL
signals use 0-13 VDC levels to produce a periodic negative going pulse (2.5 ms wide
every 30 ms).
4. A 9600/4800 baud full duplex, synchronous communication interface over an RF
channel.
5. A 9600 baud phone line or microwave communication interface (this may be RS-232
or modem data) through a Rockwell Modem.
NOTE
SitePro Controller interface functions vary from application to application and between
EDACS systems using MASTR III repeaters. It is necessary to refer to the Application
Configuration Manual for details regarding the specific hardware and software
configuration of the SitePro Controller.
