Remote Annunciator
ERROR HANDLING
An error will be reported by flashing the Communication OK light—
the rate of flashing will be indicative of the cause of the error.
1. No reply from generator control system— frequency one sec-
ond on/one second off.
2. Consecutive data errors— frequency 0.5 seconds on/two sec-
onds off.
The Annunciator, if configured for auto-baud rate detect, will try
several times at each of four different baud rates (57.6K, 38.4K,
9600 and 4800) before reporting a communication error by de-
energizing all the relays and then flashing the Communication OK
light.
LIMITS OF OPERATION
The following communication restrictions apply for multiple units
on a common RS485 line:
A maximum of 15, 1000 ohm RS485 Loads (i.e. 57.6K •
Annunciator, G-panel, H-panels, etc) can be connected to the
RS485 bus at one time.
NOTE:
14. There MUST be only ONE (1) master in the RS485 com-
munication bus. All others must be slaves (PASSIVE).
