A brand new GPS Timecode source.
This was a spare unit that we never got to use.
This unit has the optional 10Mhz and 1KHz GPSDO frequency outputs installed.
It is the DC power version of the ES-101 - normally power is applied on pins 1 and 9 of the rear panel DB9 serial port connector. For ease of connection, an additional DC power input jack has been installed on the rear panel so that the RS-232 port is left free for use by a conventional serial cable (but note that the DC input voltage is still connected to Pins 1 and 9). The internal coin cell battery maintains settings if the power is disconnected.
