Page 3: Introduction
An internal 3V coin cell battery maintains the GPS receiver board memory. If this battery is replaced with a new coin cell or the coin cell is dead, this will affect how the ES-185U obtains GPS lock from a cold start (i.e. main power is removed from the unit and the battery backup is off). -
Page 4: Standard Features
DB-9 connector. 4.2 Outputs The rear-panel of the ES-185U provides access to all outputs via various connectors (XLR, BNC & DB-9). Please refer to section 9 for more details. ESE Time Code: The most efficient and cost-effective method for time code distribution in a Master Clock/Remote Clock System employs the ESE Time Code output. -
Page 5: Setup Features
The Primary Settings tab allows the user to set the time and date of the ES-185U (when it is not locked to GPS), the time zone offset, the TC89 Hour Format, the Display Format, the Second Offset and the Millisecond Offset. -
Page 6: Option Ntp Setup
Option NTP allows the ES-185U to act as a network time server. The Master Control Panel software, a web page interface or a telnet session may be used to set up the ES-185U when option NTP is ordered. When option NTP is ordered, the ES-185U needs to be assigned a permanent IP address. This can be done using DHCP (Dynamic Host Configuration Protocol) or by using a fixed IP address. -
Page 7: Dhcp Setup (Factory Default)
5.4.1 DHCP Setup (factory default) This method of setting the IP address of the ES-185U can be used if the network has a DHCP server. Using this method automatically assigns an IP address to the ES-185U. When the ES-185U is shipped from the factory, the unit is already set up for DHCP Setup mode. -
Page 8: Web Interface
The ES-185U is supplied with a built-in Battery Back-Up/Charger System. The battery is capable of maintaining the ESE (TC89 and TC90), 1 PPS and ASCII outputs during a power outage for up to 4 hours. The SMPTE and IRIG-B outputs are not maintained during power outages. The display is disabled during power outages. If continuous displays during power outages are required, a UPS (Uninterruptible Power Supply) is suggested. -
Page 9: Options
Clear: When this option is specified, the ES-185U is supplied with a clear anodized front panel. DC: The ES-185U can be ordered from the factory to operate exclusively from a DC source. Two versions of this option are available, 12 VDC and 28 VDC. The range for the 12 VDC is +10 VDC to +16 VDC and the range of the 28 VDC is +20 to +34 VDC. -

Z14. The microcontroller generates the 1 KHz signal, which is buffered by Z1. NTP: When Option “NTP” is specified, a NTP port is supplied with the unit that allows the ES-185U to act as a network time server. The settings of the ES-185U may be changed using the network interface as well. -
Page 11: Rear Panel Connector Pin Designations
Note: If connecting SMPTE to an existing non-ESE Master Clock System (using SMPTE time code), it is recommended to connect the balanced output of the ES-185U, using pins 2 & 3, to the existing system (unless the existing system requires an unbalanced signal). -
Page 12: Antenna Mounting Instructions
5. Route the antenna connector/cable through the 5/8" hole and then fasten the Antenna to the deck plane using two (2) #4 screws. 6. Connect the antenna connector/cable to the "Antenna" connector on the rear panel of the ES-185U Master Clock. -
Page 13: Antenna Cable Tests & Alternatives
One of the main concerns when using a GPS receiver (Master Clock) is the distance between the antenna and the receiver. The ES-185U Antenna is supplied with 16’ 5” of coax cable which can be connected directly to the clock. If more cable is required an in-line amplifier may be necessary. -
Page 14: Ese Test Results
The ESE factory conducted several tests which demonstrate how the ES-185U/GPS Antenna can be expected to operate for given sets of circumstances. All tests were conducted at ESE (in El Segundo, CA) in 1998 and due to the architecture of the GPS Satellite Constellation, can be considered applicable most anywhere in the world. -
Page 15: Application Notes
Raven specs the maximum RG-58 cable that the LA-12F can drive is 50 feet. ESE's test results may indicate that longer lengths of cable may be used. We are not inferring that the longer cable lengths should be used. We are only reporting the results of our tests and repeat the caution mentioned earlier. -
