Weight: 0.118 Kg (no batteries)
Power consumption: 70 mA (3 Volts, typical)
Connectors:
“Lemo/TC”: Lemo series 0B 5-pin (matching connector
FGG/JGG.0B.305.CLADxx)
pin 1: ground
pin 2: LTC IN
pin 3: ASCII IN / OUT
pin 4: Tune reference 1.92 MHz out / DC-IN 6 to 18 Volts

(adjustable output level)
“Lemo/ACN”: Lemo series 0B 5-pin (matching connector
FGG/JGG.0B.305.CLADxx)
pin 1: ground
pin 2: LTC IN /USB 5V Input
pin 3: ACN: USB D+ / RS232 TX / Event Switch to Pin 4 / GPO
(General Purpose Output TTL)
pin 4: ACN: USB D- / RS232 RX / Event Switch to Pin 3 / GPI (General
Purpose Input TTL)

Lemo/ACN remarks:
•
GPO is a timer-driven output with TTL output signal (47 Ohm series resistor)
•
GPI is a timer-driven input and even a timer-driven output with an open-drain transistor. It
has configurable pull-up (30k) and pull-down (20k) resistors.
•
The event switch has a 200 mA fuse between pin 3 and 4
Antenna: SMA-F
