7.1.1 Serial Interfaces
Depending on the number and version of the system, the parameters for the serial interfaces can be configured
in this menu.
Baudrate: The speed with which the serial telegram is to be transmitted:
300, 600, 1200, 2400, 4800, 9600, 19200
Framing: Structure of the telegram:
7E1, 7E2, 7N2, 7O1, 7O2, 8E1, 8E2, 8N1, 8N2, 8O1
String Type: Meinberg Standard, SAT, NMEA RMC, Uni Erlangen, Computime, Sysplex 1, Meinberg Capture,
SPA, RACAL, Meinberg GPS, NMEA GGA, NMEA RMC GGA, NMEA ZDA, ION, 6021, IRIG-J
Mode: You can configure an interval (per second, per minute, on request "?" Only)
for the outgoing time string. If the operating mode is set on "Request", a
connected client must send a "?" to receive the time telegram in response.
Features:
MRS PPS Plus String
If the system has the MRS "PPS plus string" option, the baudrate and framing for the incoming time string must
be configured via this submenu.
Meinberg Capture *only for specific units*
This option is for systems that have a cap input. The event is triggered by a negative edge.
Two operating modes are available for the output of the capture time stamps, "on request ? Only" and "au-
tomatically".
on request "?" only
The triggered events are stored in a buffer of the reference clock. As soon as a "?" is sent to the reference clock
via a serial connection, the stored events are transferred from the buffer.
automatically
In this mode, the capture events are output directly on the serial interface.
