Merlock

Standard Centronics Merlock v2 (no onboard cues).

A custom Centronics Merlock v2 (w/12 onboard cues)

Another Custom Centronics Merlock v2 (w/12 onboard cues) TRMPyro branded

This is what the Centronics connector looks like. It's mounted at the bottom of the plate to allow more room for the onboard cues and MMSE/Merlock board.

This was an ODA Style merlock, they I put into a new case with Salzman Style connectors.

This is another ODA Style Merlock that I converted to Salzman Style connectors.

Since the Salzman connectors are Cues 1-15 and 16-30, I repurposed the onboard cues 11 and 12 as cues 31 and 32.

This is my 3rd ODA to Salzman convert. This one might be a little older model as the LEDs are slightly different and layout of the charging ports differ.

Inside a Merlock, some have the phoenix style pluggable connectors attached to the MMSE/Merlock board like this one. This one does NOT have onboard cues as you can see the board is close to the top of the plate. It's a lot more crazy in that area with the onboard cues and longer standoffs are used.

There are pluggable connectors for the battery and centronics ground cable. The battery has velcro to keep it down. Some have tie downs or a metal bracket in addition to the velcro to keep the battery in place.

A TRMPyro board drives the LEDs and connects to the MMSE/Merlock board via ribbon cable.

This shows the circuit protector and some of the terminals.

More terminals and the keyswitch.

Here's a view of the board with the ribbon cable disconnected. This one has the Phoenix style connectors added to it for the cues. The connector in the middle right is an alternative connector to flash program the board. It is also used to connect to the LCD/Buttons on a v3 Merlock.

Here's a view of a board that does NOT have the Phoenix style connectors on the cues. Each cue wire is directly soldered. It actually looks cleaner this way, but you can't easily detach the board from the case.  This picture actually shows a programmer connected to the middle right connector. You can program (update firmware) via the PC without using anything but the normal RS485.
