New Features on the OPTM
The OPTM module replaces the OPTO module. The module was updated to allow a separate
connection to Pin 1 the SMI Port
1
. For some controllers, this pin is Power for others it is Driver
Enable.


Product Overview
All optically isolated I/O lines have maximum frequency cutoffs. The 24 V model has an
effective cutoff at 10kHz, while the 5 V model can pass up to 500kHz.

Inputs: All optically coupled inputs accept differential voltages (-V, +V). The 24 V model has
an effective cutoff at 10kHz, while the 5 V model can pass up to 500kHz. If only the inputs of
the module are used, the external power supply is NOT required, as the optical-couplers will

draw current from the input signal to power the input circuit, which will be isolated from the
SilverLode device.

Outputs: The optically coupled outputs are single ended output lines driven by an N-channel
MOSFET in an open-drain configuration (sinking output). Use of the outputs requires the
module to be powered by an external DC source. The voltage supplied sets the voltage and
power of the output signals.

Powering the Optical I/O Module
Most of the electronics and microchips of the OPTM I/O modules circuitry are powered by the
+5 VDC, 100mA internal supply from the SilverLode controller/driver. A SilverLode device
must be connected to the module and powered for the I/O module to operate.

Powering the +12 to +24 VDC Optically-Isolated Outputs
In order to use the optically coupled outputs, a regulated supply providing +12 to +24 VDC is
required to be connected to pin 1 (+V) and pin 2 (Common) of terminal 1. The current rating of
this supply will be determined by the amount of current needed to drive the output signals.
Each output is capable of driving 1 A. The minimum current required to power all seven
outputs under no load conditions is 150 mA. When all outputs are off, 55 mA is required to
keep the output circuits active. This is required if optical isolation from the SilverLode device is
desired on the outputs.

Configuring for the SilverNugget N3 Driver Enable Pin 1
The ENA / V+ terminal on the OPTM
allows complete control over the Driver
Enable line. If +10 to 48 VDC is not
supplied to " ENA / V+", the servo's
drivers will be disabled. To power Driver
Enable, Pin 1, place a jumper wire or
control switch across terminals Fused
and ENA / V+. When using an alternative
supply, ensure that the supplys DC
common ground is connected to the
SilverLode DC common ground.










Note: See How to Use below for basic setup information with a SilverNugget N3 and
SilverDust D2 (IGB).

Input Signals
The QCI-OPTM-24 device accepts input voltages ranging from 12-24 VDC. The QCI-OPTM-5
version accepts +5 VDC inputs as a factory default. The OPTM-5 can only accept 12-24 VDC
input signal if an external resistor (2000 Ohm) is added in series to each input. Voltages
greater than +5 VDC applied to a 5 volt input may cause device failure and voids the
manufacturers product warranty.

Output Signals
All optically isolated outputs are capable of sinking up to 1 A. All 7 combined are fused at 5 A.
The 12-24 VDC line serves as the reference for the outputs. The OPTM inverts the SilverLode
internal logic. A logic high (the default state) will open the output circuit, preventing current
flow. A logic low will close the circuit and allow the output to conduct current.

must should be used.








Converting From Sinking To Sourcing Output
To convert a sinking output to a sourcing output, place a pull-up resistor between the output
terminal and the supply voltage. Calculate the resistance from the following equation. The
sourcing output signal will follow the I/O directly. A logic high within the SilverLode will provide
sourcing 24 V at the output, while a logic low will provide 0 V, relative to the power supply
ground.



R = [(V

- V

)/(I

NOTE: The 0.70 multiplication factor provides a safety margin when finding the nearest
standard resistor.

Using the Analog and TTL Connections
A separate connector is available on the board to allow direct connection of signals to the
SilverLode. A set of seven jumpers, JP1 to JP7, is used to break the connection from the
SilverLode to the optical couplers. The jumper(s) are removed in order to break each
connection.

NOTE: When using the direct I/O no isolation is provided on the given I/O line

Power Connections
A terminal block is provided for connecting power and communications to the SilverLode. The
power is fused to both the 15 Pin high-density connector and a terminal (Fused power).

Communication Connections
Communications can be either RS-232 or RS-485. Serial communication connections are
available through either the labeled screw terminals or the RJ -11 connection. The RJ -11 pin
out is listed on the specifications page of this document.

SMI Port
The SilverLode Multifunction Interface (SMI) Port is the 15-Pin HD D-Sub connector
(DB15HD). A DB15HD Interface Cable (SMI) connects the SilverLode controller's SMI port to
the modules SMI port.

Optional RS-485 Termination Jumpers
