User Guide 1
The VMM1210 is a general purpose programmable logic controller (PLC) for
vehicle and other DC applications with steady state voltages less than 32V. It has
12 inputs and 10 outputs as well as a CAN/J1939 communication port.
Figure 1: VMM1210 controller
This module is 100% compatible with other Vansco Multiplexing Modules.
The VMM1210 performs the following tasks:
Receives Digital/Analog/Frequency inputs:
The VMM1210 has 8 digital inputs capable of reading either active high
or active low type digital inputs. In addition, it has 4 inputs capable of
reading analog voltages, frequency values or active low type digital inputs.
Activates Outputs:
The VMM1210 has 8 high current (10A max) high side outputs. In
addition it has two low current (3A max) outputs capable of driving either
high side or low side loads, and can also be arranged in an H-Bridge
configuration. Outputs can drive any type of vehicle load including lights,
relays, solenoids, fans, etc.
Monitors Outputs:
The VMM1210 monitors its 10 outputs continuously for fault information.
Faults include short circuits (to ground or power), over currents and open
load. The VMM1210 allows systems to reduce the number of fuses by
allowing the outputs to protect themselves electronically.
1. About the VMM1210
2 VMM1210
About the VMM1210
In the event of a fault, the VMM1210 will disable the output(s) that are
faulted. The automatic recovery of faulted states can be turned on or off
(for safety reasons). If it is turned on, the automatic fault retry can be
adjusted to suit a variety of safety related situations.
Open load detection allows for the detection of open (burnt out) loads, this
detection can be turned on or off and can also be modified to check only at
power up of the system or continuously.
Over current levels can be adjusted in one amp increments anywhere from
1A to 12A to allow the system to react more like various fuse types.
Communicate Input/Output State Information:
In order to multiplex, the VMM1210 must be able to communicate its
information to other CAN/J1939 based equipment in the vehicle. The
VMM1210 does this by transmitting J1939 messages representing the
states of its inputs and outputs and other ladder logic based equipment.
These messages are broadcast type and can be read by and acted on by any
other module connected to the same CAN/J1939 network.
Processes Ladder Logic:
Ladder logic is a graphical representation of standard logic (AND, OR,
NOT, etc). The VMM1210 processes ladder logic written using the
Vansco Multiplex Module Software package (VMMS). The ladder logic
defines which inputs or arrangement of inputs turns on which outputs on
the module. The inputs and outputs in the ladder logic can be from one or
more modules connected together in a system via the CAN/J1939
network. For more information on the VMMS package, please refer to the
VMMS User Guide, or the VMMS help files for information.

10 VMM1210
Inputs
The VMM1210 has 3 main types of inputs, as follows:
Programmable digital inputs (can be used as active high, active low, or power
control)
Dedicated addressing inputs
Programmable multi-purpose inputs (can be used as analog, digital, or
frequency)
Note: Do not connect inputs directly to unprotected inductive loads such as
solenoids or relay coils, because they can produce high voltage spikes that
may damage the VMM1210. If an inductive load must be connected to an
input, use a protective diode or transorb.
3.1. Programmable Digital Input Types
Digital inputs are typically used with electrical signals and switches that are either
on or off.
There are 2 types of programmable digital inputs in the <Product_Name>:
Digital Inputs (active high or active low)
Power Control Digital Inputs
These inputs can be programmed as active high or active low and as power
control inputs using the VMM Software package.
3.1.1. VMM1210 Programmable Digital Inputs
The VMM1210 has 8 programmable digital inputs:
INPUT1_D through INPUT8_D.

3.1.1.2. Programmable Digital Input Configuration
Digital inputs are configured as active high or active low by using pull-up or pulldown resistors internal to the module.
When the input is configured as active high, an internal pull-down resistor is
used, and the input will be active when it is switched to battery voltage.
When the input is configured as active low, an internal pull-up resistor is used,
and the input will be active when it is switched to ground.
3.1.1.3. Programmable Digital Input Installation Connections
A digital input is typically connected to a switch that is either open or closed.
When the switch is open, the pull-up or pull-down resistor will ensure that no
signal exists on the input pin, which will be interpreted by the VMM1210 as
inactive.
When the switch is closed, the input is connected to either battery voltage or
ground, which will be interpreted by the VMM1210 as active.
Active-high input
The active-high output must be connected to battery power to ensure that there is
a battery connection when the state of the input changes.

Inputs
3.1.2. Power Control Digital Inputs
Any of the programmable digital inputs, INPUT1_D through INPUT8_D, may be
configured as power control inputs.
Power control inputs generate an internal signal in the module allowing it to
“wake up” and turn on its main internal power supply. This wakes up the main
processor and allows ladder logic to process.
If no power control inputs are selected in software, the VMM1210 “wakes up”
as soon as power is applied to the unit.
By default, ladder logic files define INPUT1 as Master Power. If Master
Power is active, the VMM assumes that all other VMMs are active in the
system. It then performs Plug and Play functions as well as network fault
functions based on the assumption that all modules are awake.
A VMM that is blank will enable the Master Power signal so that it will
perform Plug and Play at power up.
It is possible to define the Master Power input in ladder logic. Review the
VMMS Help for details on this.
If you want plug-and-play and network fault-detection functionality, you must
ensure that the input defined as MASTER POWER (INPUT1 by default) is given
power control functionality on each module.
At least one input on each module should be dedicated as power control.
3.1.2.1. Power Control Inputs Configuration
Power control inputs can be programmed as active high or active low. If an input
is programmed as power control and active low, you need a low (ground) signal
on that input pin to wake up the module. If an input is programmed as power
control and active high, you need a high (battery) signal on that input pin to wake
up the module. If you change the active state of that input in ladder logic and
download this change to the module, the signal connected to that input pin must
also change states in order to wake up the module again via that input.
14 VMM1210
Inputs
For example, assume input 2 is programmed active high and power control and
the wire harness has an active high dash switch connected to this input. Now
assume we change the active state of this input from high to low and download
this new logic to the module. The module will receive the new logic and
immediately after download will turn off (assuming input 2 is the only active
power control input during the download). The module will not turn on again until
the signal to the input 2 pin is physically rewired such that it switches ground
instead of battery.
Note: Changing power control settings on a VMM1210 may prevent you from
being able to wake up the VMM unless you make corresponding changes to
your wire harness and/or input connection arrangement.
3.2. Addressing Digital Inputs
Digital inputs ADDR1, ADDR2, ADDR3, ADDR4 and ADDR5 are dedicated
address inputs. These inputs are used to set the system address on the module
such that it is unique among all other modules in the system. The maximum
allowable addresses in a VMM system is 31 including all devices on the bus
(VMMs, PGM, LIMs, etc.).
These inputs are all active-low inputs with internal pull-up resistors. The inputs
are read when the module starts to indicate which portion of ladder logic the
module is to run. The state of these inputs must be valid before turning the VMM
on. It is recommended that these inputs be permanently grounded (depending on
desired address) in the vehicle harness to ensure a valid state before power up.
The addressing arrangement is shown in the following table, which shows the
required inputs that need to be active and floating (active shown as 1, floating
shown as 0).
