Pulsar Interface RS485-TTL EN54C-LCD

The RS485-TTL „INTR-C” interface is intended for cooperation with PSUs of the EN54C-LCD series. Interface enables connecting of PSU to RS485 bus remaining galvanic isolation. Communication in RS485 bus is due to a two-way channel, differential in a half-duplex system where transmitting and receiving data is alternate. * Power supply: 3.3VDC power through SERIAL outlet * Compliant with standards: Permission of Scientific and Research Centre for Fire Protection - National Research Institute for use with power supplies of EN54C-LCD series in fire alarm systems * Dimensions: 63 x 20 x 50 [+/-2 mm] * TTL transmission’s speed: 115200 bauds * Connection with power supply: SERIAL * Indication: LED optical indication * Warranty: 3 years from production date * Notes: - cooperation with the PowerSecurity web application - galvanic isolation between RS485 interface and TTL
