Elmes Electronic RD448 Manual

This receiver is designed to use in remote control and access control systems with large number of key-fob transmitter users and required high
level of access control verification security. To achieve intended functional performance the receiver includes the following features & functions:
- 448 key-fob transmitter user memory (model RD1-448) or 1000 key-fob transmitter users memory (model RD1-1000),
- access to receiver programming procedures protection by user editable four digits PIN code password,
- possibility of deleting a single key-fob user without need to clear entire user memory,
- highly secure KEELOQ® dynamic code for remote key-fob user identification,
- three digit bright LED display for user number display, easy programming, user key-fob learning and deleting,
- very sensitive radio superhet receiver allowing better data signal selectivity and better operating range,
- non-volatile memory log of last 6144 events (model RD1-448 only) including date, user number and key-fob button,
- TAMPER switch with terminals allowing receiver's case opening detection,
- wide range of power supply voltages: 10...35VDC or 24VAC.

Operation.

The use of a key-fob transmitter learned to the receiver's memory sets on its one of two relay outputs for:
- certain user programmed period of time (pulse – mono stable operation), or
- until a next use of key-fob transmitter is made ( on/off - bistable operation).
The digital LED display will indicate number of used key-fob transmitter while receiver's power on LED will change color (only if output one is
set to on). Two pulses signal on relay set on and one pulse signal on relay set off would be generated at the receiver's signal output S. Also, the
event will be memorized in non-volatile event memory log for future reference.
Mini-USB connector on the receiver's board allows communication with PC. To connect the receiver to PC a popular Mini-USB cable with plug A type at one
end (PC) and 5-pin mini-USB plug B type (Canon) at other end must be used. The cable is not included in the receiver set.

Event Memory Log.

The receiver is capable of memorizing last 6144 events. Every time a valid command from key-fob transmitter is received, it's user number
(0...447) is registered in the memory log along with information on used transmitter's button (0..1) and current date/time. The content of the
receiver's event memory log may be read/printed out for reference or verification with the help of external personal computer (PC). Connection
of the receiver and the PC is made by the use of Mini-USB cable. In addition, a dedicated software "RD Reader" supporting data log reading
should be downloaded from manufacture's web site
chronological data log to PC in form of Microsoft Access® (*.mdb) data base file. Advanced editing and report listing of the *.mdb data file
content may be done using Microsoft Access®, Lotus Approach® or Open Office® commercial software.
RD receiver users are advised to read event memory data log the more frequently the higher the number of key-fob transmitters in the receiver's
memory. In a sample system with 448 key-fobs and their estimated twice use daily, receiver's event log overflows after approximately 6 days.
New event data is overwritten on existing data log in the memory.

Internal Clock (RD448 only).

Though the RD receiver's memory is non-volatile type protecting data content in case of power cut off failure, the internal clock device is not
protected and will stop time count on power off. Registered event data will therefore have incorrect timing after power supply is restored, pro-
portionally to the power cut off timing. In order to maintain correct event timing, a battery backup power supply of the receiver must be used.

Access Control.

RD1000 receiver may be used to design access control system. To do so, the receiver must be mini-USB cable connected to PC. Every time key-
fob transmitter is used its number along with used button number are sent to the PC via virtual COM port (*). If, within 100ms, PC does not
confirm receipt by setting logic 0 at TX output of the COM port, the receiver's relay output would remain off (**). This feature allows design
own access control system in which one or more key-fob users may be temporarily or permanently restricted from entering secured premises.
Elmes Electronic does not offer specific access control software for installation on PC.
Access control mode is also available with the RD448 receiver model and requires solder shorting JP3 at bottom side of the receiver board. In
this mode, the content of event memory log can not be read.
(*) In ASCII format as: "NNN-P" followed by CR and LF commands, where NNN stands for key-fob number and P (0 or 1) for button used.
(**) If receiver is not connected to USB port, a logic 0 is provided at at input RX securing
receiver's relay set on.

PIN Code Protected Access To Programming Procedures.

Access to receiver's setup (Programming Procedures) is protected by four digits PIN code. It
does not allow unauthorized persons to implement changes in receiver's setup nor deleting or
adding new key-fob users. Initial PIN code set by the manufacturer is "0000". System owner
or administrator should change manufacturer's PIN code to own (simple PIN codes, e.g.
"1111" or "1234", should be avoided).
NOTE! To recover factory „0000" PIN code, if user's code is lost or forgotten, the re-
ceiver must be send to distributor or manufacturer. Factory code refurbishing deletes
receiver's entire key-fob memory content.

Description of jumpers.

JP1 set on will result in key-fob number display for only 5 seconds. Set off will display last
key-fob number until next key-fob is used.
JP2 set on will result that only one output channel is active and responds to any user selected
key-fob transmitter button. Set off both output channels are active and respond to two buttons of used key-fob, e.g. buttons 1 & 2 or 3 & 4
of Elmes CH4H transmitter.
