Page 11: General Information
Our NetClock is a direct response to customer needs for cutting-edge synchronization technology at an affordable price. The Model 9183 is called an NTP time server as it provides disciplined timing using NTP (Network Time Protocol), and is also called a Master Clock as it meets or exceeds the NENA (National Emergency Numbers Association) master clock standard.
Page 12: Warranty Information And Product Support

The Spectracom P/N for the power supply is PS06-0E0J-DT01 DC input: 9.5 to 30 VDC, 10 watts, through a CE/UL/CSA-approved power adapter (supplied).
Page 19: Installation
(Refer to section 3.6.1). Note: Use of a window-mount antenna with a Model 9183 NetClock is not recommended if using an OCXO (Option 5) or Rubidium (Option 4) type oscillator in the NetClock.

Note: Auto-Negotiate, which determines the network settings to use, only occurs at power-on. Always connect the Ethernet cable before powering-on the unit for the first time. If the Ethernet cable is connected after power-on, the unit will default to 10 Mbps and half duplex. Model 9183 Instruction Manual Page 2-3...
Page 22: Gps Antenna Installation
Using Spectracom CAL7xxx or Times Microwave LMR-400 coax, the maximum antenna cable length permitted is 200 feet because the Model 9183 allows 12 dB of loss. An amplifier is needed whenever antenna cable lengths exceed 200 feet. Installations requiring longer antenna cables may use the Model 8227 Inline Amplifier, or lower loss cable.
Page 23: Model 8224 Gps Splitter
The Model 8224 should be installed indoors. 2.4.4 Model 8226 Impulse Suppressor Spectracom recommends the use of an inline coaxial protector for all products with an outside antenna. Spectracom offers the Model 8226, Impulse Suppressor, to protect the receiver from damaging voltages occurring on the antenna coax.
Page 24: Model 8227 Gps Inline Amplifier
2.4.5 Model 8227 GPS Inline Amplifier An inline amplifier is required whenever GPS antenna cable lengths cause greater than 12 dB attenuation. Using Spectracom CAL7xxx coax, an amplifier is needed whenever antenna cable lengths exceed 200 feet. The Model 8227 GPS Inline Amplifier, shown in Figure 2-2, extends the maximum cable length to 600 feet.
Page 25: Ethernet Network Cabling
When connecting directly to a PC, use a crossover wired cable. 2.5.1 Optional CNC3000 cable kit: Spectracom offers an available cable kit called the CNC3000. This kit consists of three cables: 1) Six foot RS-232 Setup port cable DB9M to DB8F for initial configuration 1) Six foot Cat 5 crossover LAN cable for direct PC connection 1) Six foot Cat 5 patch LAN cable for LAN hub link.
Page 26: Remote Port And Serial Comm Port Output Pin-Outs And Wiring
Serial RS-232 Comm ports. 2.6.1 Serial Comm ports The rear panel of the Model 9183 has two RS-232 SERIAL COMM ports that are available to synchronize peripheral devices. These ports can provide RS-232 output data to synchronize external devices that can accept RS-232 Data Formats as an input. The available Data Formats are listed in Section 6.
Page 27: Remote Port
RS-485 characteristics make it ideal to distribute time data throughout a facility. Each Remote Output can provide time to 32 devices at cable lengths up to 4,000 feet. Refer to Figure 2-6 for a schematic representation of each RS-485 output driver. Relative to RS-485 specifications, the A Model 9183 Instruction Manual Page 2-9...
Page 28: Remote Output Usage
Error! Objects cannot be created from editing field codes. Figure 2-6: RS-485 Output 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.
Page 29: Connection Method
A branched or star configuration is not recommended. This method of connection appears as stubs to the RS-485 transmission line. Stub lengths affect the bus impedance and capacitive loading which could result in reflections and signal distortion. Model 9183 Instruction Manual Page 2-11...

Page 31: Figure 2-9: Wire Strain Relief
Most RS-485 connections found on Spectracom equipment are made using a removable terminal strip. A jaw that compresses the wires when tightened secures the wires. When using small diameter wire, 22-26 gauge, a strain relief can be fashioned by wrapping the stripped wire over the insulating jacket as shown in Figure 2-9.

Page 33: Figure 2-12: Model 9188 Rs-485 Interface
Spectracom Model 9188 is an Ethernet Time Server that supports NTP and SNTP time protocols. The Model 9188 accepts Format 0, Format 2 or Format 8 (Format 8 is not available on all Model 9188’s- contact Tech Support for additional information) and connects to the RS-485 data bus through a three-position terminal block.
Page 34: Termination
Figure 2-8. In a split bus configuration, terminate the devices installed on each end of the bus. Most Spectracom products include a built-in termination switch to terminate the RS-485 bus when required or a resistor is supplied with the equipment if no termination switch is available.

To use the MD5 authentication in Unicast mode, both the NTP client and the Spectracom NTP server must contain the same key ID / key string pair and the client must be set to use one of these MD5 pairs.
Page 98: Ntp Support
When operating in multicast mode, the Spectracom NTP server can be configured to append MD5 authenticators to each packet. To enable this, check the box labeled “Use MD5 authentication with key …” under the NTP Broadcast setting, and enter the key ID to be used.

For example, use all abbreviations, spellings, URLs, and company departments recognized by the Certificate Authority.

Note: Oscillator disciplining is dependant upon a very stabile reference 1PPS input signal. Due to this, the Modem dial-out option (Option 3) available for the Model 9183 cannot be used for oscillator disciplining and hence does not result in enabling 10MHz frequency outputs when time sync is achieved via these time sources.
