The EC485 converter is an accessory for both the Fireye® FLAME-MONITOR™ flame safeguard control system and the 45FS1 and 45UVFS1 Flame Signature Scanner™ controls. The EC485 is an RS232 to RS485 converter used to perform the following functions:
- Customize the operating control messages and lockout alarm messages of the E300 Expansion Module.
- Interface between an IBM compatible PC running the FS700 Communication Software and the 45FS1 and 45UVFS1 Flame Signature Scanner to provide remote communications capability.
- Interface between an IBM compatible PC running the E720 Communication Software and the E340 Burner Management Control System to provide remote communications capability.
The EC485 provides the means to directly connect to any device that has RS485 communication capability
The EC485 also includes a 120 VAC to 12 VDC power supply
RS-485 Driver Control, RTS / SD Jumper:
The RS-485 side of the converter must be enabled to transmit data, and disabled when not transmitting. Via a jumper on the converter, either “RTS” or “SD” is selected as the control means to automatically enable and disable the converter.
With SD (Send Data) control selected, circuitry within the converter automatically controls the transmitter by sensing the data on the RS-232 side. This circuitry enables the driver during data transmission and disables the driver after the last character has been sent.
With RTS (Request To Send) control selected, the external software controls the driver by raising and lowering the Request To Send line on the RS-232 side. Because the RTS timing is not precisely controlled, this method is not usually suitable for Windows based systems.
