systems
ekey LAN/RS485 converter –
The ekey converter function as a serial device manager and a
translator between two sides: TCP/IP and RS-485 as explained
next.
On LAN side –
Each converter on the network should be assigned unique
static IP address to manage up to 4 sets (1 set = 2 devices… 1
scanner + 1 control unit) per single static IP.
Each converter is connected to the network over the LAN using
RJ-45 plug where the TOCAnet server application is running on
a server with another static IP.
You can add multiple converters per system, each will have its
own static IP address
On RS485 –
The converter has one port that supports RS-485 for
communicating with the fingerprint scanners and control units.
Each ekey converter supports 4 sets (1 set = 2 devices… 1
scanner + 1 control unit).
The internal and external unit must be connected by two cables
as follows:
o Data Cable or Bus Connection: clamp 1 and clamp 2 of
each control unit and fingerprint scanner on the same
bus are daisy chain connected in sequence to the
corresponding clamps on ekey converter RS-485 port
using CAT 5/6 or bell wire with minimum wire cross
section of 0.22 mm². The bus is terminated by 120
ohm resistor. When multiple sets are daisy-chained
together, it is highly recommended to use control and
scanner units interchangeably for ease troubleshooting
and faultless operation in case the wiring is broken.
o Power Cable and connection: each fingerprint scanner is
powered by its correspondent control unit using a two
conducts
with minimum wire cross section of 0.75 mm².
ekey converter is powered by any single device.
