Packet Structure
Message Format
Figure B shows the message format. A data block of length n is composed of 2 synchronization bytes, 1
octet for the header and n-1 octets for the message data.
Figure B: Message Format for Asynchronous Serial Communication
Octet Signals and Bit Order
9600 bps; 8 data bits, no parity bit, one start bit, one stop bit
Line idle is binary 1 (standard)
Each character has one start bit (binary 0), 8 information bits (least signicant bit rst) and one stop bit (binary 1)
The signal levels shown in the timing diagram are inverted from the voltages that appear on the RS232 connector.

RS-232 Serial Box
Overview
The RS-232 Serial Box is a data interface radio transceiver which can be connected to any system that uses an RS-232 serial port.
The device communicates with ILLUMRA wireless switches, sensors, and receivers and allows other systems to communicate with
ILLUMRA wireless controls.
Compatible Devices
Single Rocker Self-powered Wireless Light Switch; E3T-S1Axx
Dual Rocker Self-powered Wireless Light Switch; E3T-S2Axx
Handheld Self-powered Wireless Light Switch; E3T-S2Hxx
Key Card Access Switch; E3T-C1AWH
SLT Wireless Sensor; E3T-Rxx-2INBP
Self-powered Wireless Occupancy Sensor; E3T-Mxx-SB24
More compatible devices available
Components Included
The following items are included with this product:
A -- (1) ILLUMRA RS-232 Serial Box
Installation
The RF Serial Box can be mounted almost anywhere. The following considerations should be taken into account:
Mount within range of wireless switches and receivers; obstructions limit range (see specications)
Mount in area where power source is available (see specications)
Do not exceed max RS-232 cable length
For optimal range:
-- Do not mount or place RF Serial box close to the oor
-- Do not mount or place RF Serial box inside a metal housing
Connections (Interfacing Protocol)
The RF Serial Box can accept external power through either the power connector, or through pin 9 of the DB9 port. When using
an external power source, connect to the power jack using the provided screw terminals. The power connector accepts 8-28 VAC
or 8-30 VDC. The power connector is polarity insensitive, but power provided through the DB9 port must be DC, not AC, and
connected with correct polarity (+ to Pin 9, - to GND).
A standard DB-9 female connector is provided on the device. It may be necessary to connect the Serial Box to the security/control/
automation panel using a null-modem cable, but connection to a PC requires a standard straight-through cable.

Acronym Description
5 RPS Telegram from a PTM switch module received (e.g. PTM 100 or PTM 200)
6 1BS 1 byte data telegram from a STM sensor module (e.g. STM 250)
7 4BS 4 byte data telegram from a STM sensor module (e.g. STM 100)
8 HRC Telegram from a CTM module received
0-47, 9-255 -- Reserved
Operation
Verify Serial Port – Connect to terminal program, like “HyperTerminal” or “Portmon” and monitor activity on serial port. Each time
another ILLUMRA device transmits, a few copies of the data packet should ow through to the serial port.
The data received from the modules contains non-printable characters. In order to see the exact contents of the received packets, set
up a text capture with Transfer->Capture Text. An alternative to the text capture method is to run a serial port monitoring program
(use Google to search for “portmon” which is available as a free download from microsoft.com, and can display the hexadecimal values
during serial operation).
Save the le in a convenient location.
Serial Data Structure
The structure of the serial data is as follows:

H_SEQ (3 bit) Header Identication [refer to table below]
Table B: Header Identication
H_SEQ Meaning Mode
0b 000 Unknown transmitter ID received
(serial telegram only if no ID has been learned so far!)
For RPS also:
-- Known transmitter ID and unknown rocker
-- U-message from known transmitter ID received
For HRC also:
-- Known transmitter ID and unknown rocker
-- Scene switch command (last three bits of ID 0b111) from known
transmitter ID (only rst 29 bits are compared!)
Operating
Mode
0b 001 For 1BS and 4BS: Known transmitter ID received
For RPS: Known transmitter ID and at least 1 known rocker (1 or 2 rockers
operated)
For HRC: Known transmitter ID and known rocker
Operating
Mode
0b 010 New transmitter learned (If a switch telegram is received (RPS or HRC),
the rocker code (RID) is stored together with the ID.)
• Mode 3: a telegram with this header information will be sent also when
in LRN mode a transmitter which is already learned is operated again
Learn Mode
0b 110 Mode 0: Transmitter just deleted (If a switch telegram is received (RPS
or HRC), the rocker code (RID) and module ID are checked. The entry is
only deleted if module ID and rocker are known.)

Use the hex editor to open the captured text le, and the full packet is visible in hexadecimal format. Note in the packets shown, the
5th byte indicates the state of one of the buttons on the PTM module. Note that the button was pressed for the rst packet, (0x10)
and released for the second packet (0x00). This is the sequence received when a user presses and releases the button on a battery-free
wireless switch.

The enclosed device complies with Part 15 of the
FCC Rules. Operation is subject to the following two
conditions: (i.) this device may not cause harmful
interference and (ii.) this device must accept any
interference received, including interference that may
cause undesired operation.
Press a switch button and two packets of 14 bytes each will be received and displayed. If a repeater is in range, two copes of each packet
will be received, the later of which will contain a bit indicating that the packet has been repeated.
In order to view the actual contents of the data packet, stop the text capture process by selecting Transfer->Capture Text->Stop. This
step is important, as it closes the le so it can be read by other programs. Now download a hex editor program. A free one called XVI32
is available on the web.
