Time of Day Output
If using Time of Day Output, connect the time of day (TOD) output at the female RJ-45
connector labeled TOD. See Figure 13 for the connector location, and Table C for the
connector pinouts.
Note: Pins not listed are reserved for future use.
If the device receiving the time code (for example, a Cisco router) accepts an RS-232 cable
instead of an RS-422 cable, follow Procedure D to install the RJ-45-to-DB-25 TOD
converter.
Note: Before performing Procedure D, ensure that the appropriate Cisco router or NTP type
4 compatible device is installed, and power applied, per manufacturer's instructions.
