The 8-pin Lemo socket on an Archer 1 sled carries power, video signal, video ground, and tally information with the following pinout: pin 1 is power ground, pin 2 is +12V, pin 3 is video signal, pin 4 is video ground and tally negative, pin 6 is tally positive, and pins 5, 7, and 8 are not connected.
A custom breakout box can be constructed from the 8-pin Lemo connector to provide separate outputs for video on BNC, power on 4-pin XLR, and tally on 3-pin XLR for connecting external monitors and tally lights.
The tally LED system requires the LED to be oriented correctly as a diode with current flowing in the proper direction, and all cables including video and power must be connected to the monitor for the tally lights to function.
A Hirose Din plug (Digi-Key part HR212-10P-8P) can be used to create a tally cable, with a photocell soldered between pins 7 and 1 to activate the monitor's red LED indicator.
The sled's nose dial controls the sensitivity of the tally sensor function.

The pinout information was derived from the Archer 2 manual and should be verified against official documentation for the Archer 1 specifically.
The tally system design described was implemented as a custom modification and reflects one person's wiring approach rather than manufacturer specifications.
The connection between tally negative and video ground may vary depending on specific monitor requirements.
