• overriding the signal controlled stop or speed limit is possible from the cab with the special “MAN” key. Individually for each locomotive address
• acceleration and deceleration rate of locos is adjustable on an individual basis (by special configuration variables which are added to the normal NMRA set, only in Zimo decoders).
• bridging the isolation gap between adjacent track sections does not cause short circuits or undefinable conditions. 
• only one rail needs to be devided into blocks                                              more on this here

The MX9 controls 8 blocks. Each block is made up of 2 sections for a total of 16 track sections. At each track section occupancy detection and train number recognition is performed and sent to a PC or other digital display, such as Zimo’s MX9ZIA. In return “signal controlled speed limits” and "position controlled function bits" can be applied to each track section, for different automatic functions.
Signal controlled speed influence will automatically decelerate a train and bring it to a full stop at the right spot on your layout. After the signal turns “green” the train slowly accelerates again to the speed set at the cab. The system can also reduce a trains speed automaticaly, when passing a construction site for example, and resume speed again. 5 different speed limits can be applied. To save power the system can also turn power to the track off/on when a train enters/leaves a station (e.g. hidden stations).
Position controlled function influence makes it possible to automatically turn on all the lights in all the coaches of a train just before it enters a tunnel (or off as it leaves a tunnel), have a train blow its whistle at a certain location etc.

The MX9 can be used both:
- in “system-autonomous” operation (without computer) with direct control of speed limits or for automatic block control by the MX1 command station and/or
- in computer controlled applications (“STP" software controls speed limits, occupancy states and loco numbers for supervising and controlling the whole layout).

In Zimo’s automatic mode You are never lost or left out. Any engine or consist can be taken out of automatic mode at any time and controlled manually through the MX21 cab, by the push of one button! Push/Pull operation is possible without any limitations. The train will always stop in front of a signal, even in fully automatic operation, regardless whether the engine is at the front or rear of a train.

MX9V full version track section module:
Operates 16 track sections; occupancy detection, train number recognition, signal controlled speed influence, position controlled function influence, operates signal lights, supports push button switch boards. Can be used with or without PC.

MX9B track section module:
The low-cost version; without "signal controlled speed influence". Connectors for plug-in boards are provided as in the MX9V.

MX9ALA lamp driver plug-in board:
8 output drivers control 8 external occupancy indicators or 8 block signals. 4 MX9ALA boards can be used with one MX9 to drive 32 bulbs or LED’s.

MX9ASE plug-in board for speed limit inputs
With the MX9ASE boards the train can select its own speed setting by activating switches, relays etc. (without the help of a PC). For each track section two external switches (or jumpers, relays, or similar) can be connected to the MX9; the 4 possible combinations of these switches (00, 01, 10, 11) define the speed limit applied to the track section belonging to the switches.

The MX9 needs to be configured by the manufacturer in order to accept the MX9ASE board. Please let us know if the MX9ASE boards will be used when ordering a MX9.

MX9ZIA external digital display module for loco numbers display:

A straight (MX9ZIAP) and a angled (MX9ZIAW) version are available.
8-digit display that connects directly to the MX9. Up to 8 MX9ZIA  modules can be used; one for each installed MX9AZN plug-in board .

MX9ZIA displays 2 three digit, 2 four-digit or 3 two-digit loco addresses at the same time. More addresses (as in consists) will be displayed alternating. LED’s for occupancy states are provided.
