(SR) Serial Wire Sync Receive Option for slave clocks:
This option adds two-wire serial synchronization to digital clocks. Time data is transmitted over two wires ten times per second. The SR option receives time data and is typically used in slave clocks. Any number of clocks incorporating serial wire sync may be attached to a master clock. See also, the PL option for "No New Wires" synchronization. When ordering this option, simply add the letters SR to the clock model number, i.e. BRG440-SR. |
