REPARING FOR
C0405-Series RFID Controllers support direct connections for point-to-point
(host/controller) applications (RS232, RS485 and USB). Up to 16 C0405-485 units
can be networked via Subnet16 Gateway interface module and Escort Memory
Systems' Subnet16™ Multidrop Bus Architecture. Host/controller data transmission is
achieved via 5-pin or 8-pin serial interface cable.

NSTALLATION
Conduct a test phase where you will construct a small scale, independent
network that includes only the essential devices required to test your RFID
application. To avoid possible interference with other devices, do not initially
connect your RFID testing environment to an existing local area network.
RF performance and read/write range can be negatively impacted by the
proximity of metallic objects. Avoid mounting the controller within 44mm (1.75
inches) of any metallic object or surface.
If electrical interference is encountered (as indicated by a reduction in
read/write performance), relocate the controller to an area free from potential
sources of interference.
Route cables away from other unshielded cables and away from wiring
carrying high voltage or high current. Avoid routing cables near motors and
solenoids.
Refrain from mounting the controller near sources of EMI (electro-magnetic
interference) or near devices that generate high ESD (electro-static
discharge) levels.
Always use adequate ESD prevention measures to dissipate potentially high
voltages.
obalt controllers are designed to withstand 8kV of direct electro-
C
static discharge (ESD) and 15kV of air gap discharge. However, it is not
uncommon for some RFID applications to generate considerably higher ESD
levels.
For applications using multiple RFID controllers operating at the 13.56 MHz
frequency, maintain a minimum distance of at least 20 centimeters between
adjacent RF devices.
