4NMEA to1 - 4 NMEA to 1 RS 422
If the number of needed serial interfaces to control an ECDIS, a VDR or other systems on board of a vessel is not enough or the cabling between the systems contains not enough spare wires, the 4NMEA to1 module must be used. A data distribution between the connected sources is possible.
Main features
| Power supply | 24 V (9-32 V) / 500 mA |
| Dimensions | 176mm x 104mm x 41mm |
| Input | 4x RS 422 up to 38400 Baud (galv. isolated between channels and system without transmitting functionality Ui>=2V / 2 mA); telegrams according to IEC 61 162-1; IEC 2000 |
| Output | 1x RS 422 up to 115200 Baud |
| System function | Self test module after restart with output of the status to the programmed output port |
| Other features | Baud rate and data flow for each port adjustable; all calibrations of parameters can be done by a normal terminal program (for e. Hyper Terminal) |
| Applications | Multiplexing of 4 NMEA signals into one data stream, which will be transmitted to the RS 422 output port |
