# Description and specifications:
Leica DMLD (DM LD) controller P/N 301-385.160 with an RS232C connector and foot-switch connection for Leica DM series microscopes.

Basic specifications of the Leica DM LD controller:
Model: Leica DMLD (also written as: DM LD)
Leica catalog number: 301-385.160
Legacy Leitz part number: 541065
Production date: 01/98
Connectors: female DB15, male RS232C, female foot-switch connector, mains power inlet, power switch
Power supply: U100-115/230V 50-60Hz, P max 25W
Form factor: external metal enclosure

"Leica DMLD" is an analogue photomicrography system. A standard 35 mm camera is connected to shutter unit 093-050.001-000 (legacy part number 541045). Among its connectors is a male DB15 connector labelled "control panel or power supply". The shutter operates together with the Leica DMLD control panel P/N 301-385.001 (legacy part number 541044).

The entire system is very similar to the earlier MPS52 system (Leitz Leica MPS 52 / Wild Leitz MPS 52).

Based on the following observations:
- the controller offered here is also designated "Leica DMLD"
- part number 301-385.160 belongs to the same numbering group as control panel 301-385.001 (group 301-385.xxx)
- the legacy number 541065 belongs to the same 5410xx numbering group as the shutter controller and the control panel

I believe — although I do not have access to documentation that could confirm this — that this unit is also part of the Leica DMLD analogue photomicrography system, most likely serving as a power supply and shutter control module with provision for connecting a foot switch.
