GW-DMX1602
DMX 512 DECODER
The LOGIC SYSTEMS GW-DMX1602 decoder card decodes a
standard DMX512 signal into 18 channels. The card channels 1-16 are digital
outputs. The card channels 17 and 18 are analog outputs. The card can be used
anywhere within the DMX 512 controller channel group. The starting address is
set via dip switches. The digital output switching polarity can also be programmed. The DMX start code for the decoder card is zero. Multiple
cards can be used with no overlapping of channels. In the event of a DMX512
signal loss the outputs will remain at their last state.
ADDRESSING
The decoder card uses base-zero addressing. When dip
switches 1 through 9 are OFF the first card channel will be DMX controller
channel 1.
Example:
To set the starting address to 342 set dip switches as
follows.
Set DIPSWITCH SW1 switches to the following:
To get the starting
address add up the values of the switches that are on. We have base-zero
addressing so add one more. Our starting address is 256+64+16+4+1+1=342. The
card will use DMX-512 channels 342 through 359
POWER
SUPPLY
The decoder card requires a 12VDC power supply. Connect
to connector P1. See Figure 1 for pinout. The card requires 50 mADC. Add the accessory power requirements
when sizing the power supply.
DIGITAL
OUTPUTS
Connector P3 outputs the card channel 1 through 16
digital outputs, +12 VDC accessory power and common. The outputs are open
collector transistor outputs. Dip switch 10 determines how the outputs will switch.
When dip switch 10 is OFF the output
transistors will switch ON when the assigned DMX channel is above 50% and will
switch OFF if below 50%. When dip switch
10 is ON the opposite switching will occur. The decoder card can output TTL
compatible signals by installing RN3 and RN4 in their respective sockets. RN3
is an 8 pin 2 .2KWresistor network and RN4 is a 10 pin 2.2K Wresistor network.

ANALOG
OUTPUTS
Connector P8 outputs channels 17 and 18 analog outputs.
They are factory adjusted to 0-10 VDC. The outputs can be adjusted down for a
0-5 VDC output range. Trimmer R5 adjusts channel 18 gain and trimmer R2 adjusts
channels 17 gain. Counter-clockwise adjustment will lower the gain. +12 VDC is provided
on the connector for accessory power. The +12VDC current availability is
dependent on the power supply used. See Figure 1 for connector pinout.
DMX512
SIGNAL INPUT
Connector P2 accepts a USITT/1986 or USITT/1990 standard
DMX512 signal input. See Figure 1 for connector pinout. Any other signal will
give unknown results. Jumper J1 connects the terminating resistor and is used
when the card is the last one on the cable run.

GW-RLY16
The Logic Systems, Inc. GW-RLY16 converts the GW-DMX1602
16 digital outputs to high voltage, high current isolated relay contacts.
Designed to be used with the GW-DMS1602 DMX512 decoder card.
DIGITAL
INPUTS
Connector P3 inputs the card channel 1 through 16 digital
