TimeProvider 5000 Connections
1PPS+TOD Input Connections
Two of the RJ-45 ports (1PPS+TOD-1 and 1PPS+TOD-2) on the 090-50315-01
expansion version of the I/O module (Figure 1-6) are input ports for 1PPS and TOD
information transmitted at RS-422 level. See Table 1-7 for pin-outs for the
1PPS+TOD connectors.
GNSS Connection
The IMC (versions 090-50331-04 and 090-50331-05) has an SMA connector for
input from GPS (090-50331-05) and Beidou/GPS (090-50331-04) navigation
satellites to provide a frequency and time reference (see Figure 1-3). This port
supports input from both GPS and Beidou satellites for the 090-50331-04 version of
the IMC and input from GPS satellites for the 090-50331-05 version.
