NetClock/NTP Network Time Provider Instruction Manual

2-12

Spectracom offers many devices that accept the RS-485 data stream as an input reference.
These products include display clocks, RS-485 to RS-232 converters, Ethernet Time Servers,
and radio link products to meet various time applications and requirements. For information on
Remote Output usage refer to Section 2.7.2.

2.7.3 Remote Output Usage

The Remote Outputs provide a continuous once-per-second time data stream in RS-485 levels.
RS-485 is a balanced differential transmission, which offers exceptional noise immunity, long
cable runs and multiple loading. These characteristics make RS-485 ideal for distributing time
data throughout a facility.

The Remote Output can drive 32 devices over cable lengths up to 4000 feet. Spectracom
manufactures wall clocks, Ethernet Time Servers, RS-485 to RS-232 converters, and radio link
products that utilize the RS-485 data stream as an input.

Refer to sections 2.7.4, 2.7.5, and 2.7.6 for more information on time data bus interconnections.
Follow the guidelines contained therein when constructing the RS-485 data bus.
