2Product Overview
The SHoW DMX Neo (Neo) radio module wa de igned by City Theatrical, Inc. (CTI) to u e in the
SHoW DMX line of wirele theatre lighting control equipment. Thi equipment i u ed for
wirele tran mi ion and reception of DMX512-A and RDM protocol data.
The Neo radio module wa de igned to provide enhanced interference rejection, to reduce
latency of both DMX and RDM packet delivery and provide an ea ier interface to implement.
The Neo radio module can operate in two different mode : Neo and Cla ic. It i recommended,
however, to implement only Neo mode. Cla ic mode i backward compatible with the
previou generation technology, formally known a SHoW DMX. .
The SHoW DMX product line u e SHoW ID to allow device to communicate with each other.
A long a two (or more) device are programmed to hare a SHoW ID, they will be able to
communicate. The SHoW ID i programmed into the module via the “config” protocol, RDM or
an external button.
2.1 Part Nu bers
The Neo radio module come in two different ver ion . The part number and difference are
found below.
2.1.1 5792 SHoW DMX Neo Radio Module for OEM
The 5729 u e a 40-pin low profile header. The header contain all ignal allowing the unit to
be integrated in the mo t flexible way. The ignal are all TTL (tran i tor –tran itor logic) and
the voltage ource i fixed at 5Vdc.
2.1.2 5794 SHoW DMX Neo Radio Module for W-DMX
The 5794 u e a 10-pin header. The header contain ignal that directly map to the W-DMX
module. Thi ver ion ha an on board RS-485 driver and can accept voltage of 5Vdc fixed or 7-
30Vdc u ing the onboard witching regulator.

3About this Manual
Section 4 provide the pecification , notification and regulation nece ary for afe and
effective operation of the SHoW DMX Neo Radio.
Thi manual divide the two operating mode into eparate ection : Neo operation mode
implementation and Cla ic operation mode implementation. It i not recommended to
implement the latter.
Section 5 de cribe implementing Neo mode. The ection i broken into two ub ection , one
for the 5792 (SHoW DMX Neo Radio for OEM) and one for 5794 (SHoW DMX Neo Radio for W-
DMX). Neo mode implementation are the preferred method of integration.
Section 5.1.2 give example of common implementation . It i ugge ted to follow one of
the e example .
Section 6 wa intended to de cribe the implementation of Cla ic mode. However, CTI trongly
recommend it cu tomer avoid implementing Cla ic mode and thu ha excluded ection 6
from thi manual. If compatibility to older SHoW DMX product i required, Cla ic mode mu t
be implemented a an addition to Neo mode. If you are intere ted in pur uing uch
functionality, plea e contact City Theatrical at (201)-549-1160.
Section 7 de cribe the protocol and command et for the configuration mode.

Pin 1 – TxD: Thi pin i the TTL erial data output from the radio module. The data conform to
DMX/RDM when in “Neo” mode or configuration protocol when in “config” mode. Mode are
elected via the MODE0/MODE1 pin de cribed in

Table 8.
Pin 15 – Tx/Rx: Thi pin i an input to et the radio to either tran mitter mode or receiver
mode. In tran mitter mode the radio tran mit data wirele and receive DMX data wired. In
receiver mode the radio earche for a tran mitter from which to receive wirele data and
generate wired DMX/RDM data ba ed on the SHoW ID etting. See Table 4 for more detail .
Pin 16 – RxD: Thi pin i the TTL erial data input to the radio module. The data conform to
DMX/RDM when in “Neo” mode or configuration protocol when in “config” mode. Mode are
elected via the MODE0/MODE1 pin de cribed in

Table 8.
Pins 17 & 19 – General Input Bits: The e two pin control the per onality of the internal RDM
re ponder. The e input are only read at power up, and then depending on mode are u ed for
other purpo e . The e input have internal pull-up and can be left unconnected for per onality
SHoW Neo. See Table 6 for de cription of the different per onalitie . Table 7 de cribe the
function the pin take on after power up ha completed.

Pin 23 & 26 & 27 – Red/Blue/Green: The e pin are only u ed when the RDM per onality i
SHoW Baby. SHoW Baby indicate it current SHoW ID by di playing a color on an RGB LED. Pin
23 control the Red element, 26 control the Blue and 27 control the Green.
Pin 28 – IN_RANGE: Thi pin i an output that i only active when the radio i in receiver mode.
It indicate whether the radio module i receiving and i ynchronized to a tran mitter or not by
going high when it i ynched.
Pin 29 – LN_MODE: Thi pin elect the operational mode , active low for SHoW DMX Neo. Thi
pin i internally pulled high. Thi pin mu t be pulled low to enable “Neo” operation. Thi pin i
latched at re et in regi ter 0x15, after re et, the mode can be changed by writing to regi ter
0x15.
Pin 30 – 85RX_ONLY: Thi pin put the SHoW DMX Neo into RDM wired re ponder mode. Thi
pin i internally pulled high. When pulled low, the SHoW DMX Neo will drive the “485 Dir”
ignal low. Thi can be connected to a witch to effectively deactivate the SHoW DMX Neo from
the 485 bu and allow the SHoW DMX Neo to act like a RDM re ponder on the 485 bu .
Note: Thi pin can only be driven active during a DMX/RDM break through byte 23 of
current the DMX/RDM frame. Driving thi pin active at other time can cau e
undefined re ult .
Pin 31 – 85DIR: Thi pin allow an off board RS485 driver to be connected directly to the TTL
erial ignal and allow the SHoW DMX Neo to communicate on the DMX/RDM bu without the
need of a ho t proce or.
Pin 32 & 3 – Mode Selection: The e two pin are input that control whether the radio i in
“Neo” mode or “config” mode. Neo mode i for normal DMX/RDM operation. Config mode i
u ed to configure the internal radio regi ter via the erial configuration protocol found in
ection 7. The e pin have weak pull-up . See

Table 8 below for the mode election truth table.

Notes:
•When the mode bit change, the radio abort it current operation and enter the newly
elected mode.
•You can only change to “config” mode during a DMX/RDM break through byte 23 of the
current DMX/RDM frame. Selecting “config” mode active at other time can cau e
undefined re ult .
Pin 36 – Wakeup: After the radio ha been put into leep mode by writing to the leep regi ter,
thi pin i u ed to wake the radio back up. The pin i held high with an internal pull-up re i tor
and the ho t mu t pull it low to wake up the radio.
Pin 37 – Bootload: Thi pin tell the radio to enter bootloader mode. It i read on power up /
re et. If logic 0, radio enter bootloader mode. Contact CTI if you need information on how to
load new code into the radio module.
Pin 38 – Reset: Thi pin i connected directly to the re et pin of the microcontroller in the radio
and i u ed by the ho t CPU to force the radio to perform a re et. After pulling thi pin low and
then relea ing it the radio’ firmware will tart running from the beginning and will load all the
configuration regi ter with the default value . After relea ing the re et pin the radio take
approximately 60mS before it i ready to communicate with the ho t proce or.
5.1.2 Reco ended Interface Connection Exa ples
5.1.2.1 Exa ple: SHoW Baby 5 Receiver
Thi example how how to integrate the functionality of a SHoW DMX SHoW Baby 5 receiver
into your application. Figure 2 below how the connection required to imulate the feature
et of the SHoW DMX SHoW Baby 5 product operating a a SHoW DMX receiver.
In thi mode the LN_MODE ignal i tied low to put the radio module into “Neo” operation
mode. Leaving the Tx/Rx ignal input unconnected cau e the module to operate a a receiver.
Both mode bit are tied to common to permanently leave the module in the “Neo” operation,
a we will not be u ing the configuration protocol in thi example. GPI0 i connected to a
normally open witch o that we can toggle thru the 5 SHoW Baby ID that are available in thi
configuration. An RS-485 half duplex driver i connected to the TxD/RxD and 485 direction line .
The remaining ignal left all connect to LED indicator .
