Equipment Communication
The PC software communicate with the system through two protocols (RS485 and TCP/IP)
Vision:1. 0.1 Date: July, 2011 for data exchange and remote management. The communication cable should be away
from high-voltage lines as far as possible. Do not keep the communication cable in parallel
with power cords or bind them together.

1) TCP/IP Mode:
1.Cautions
Please notice the following cautions. Mis-operation may lead to personal injury or
equipment failure: PC
1) Do not energize the system before installation is complete. Never carry out installation
activities when the system is energized. Card Reader
2) All peripheral devices must be grounded.
3) It is recommended that all wires run through casing pipes which may by PVC or galvanized
ones.
4) It is strongly recommended that the length of exposed part of any connection cable TCP/IP Ethernet S witch
should not be longer than 4 mm. Professional clamping tools may be used to avoid
unintentional contact of exposed wires to avoid short-circuit or communication failure.
5) It is recommended that card readers and buttons should be installed at height of 1.4m-1.5m
above ground.
6) It is recommended to use the power supply in case for control panel, and external power 1# Controller 2# Controller n# Controller
supply for each lock.

1)The access controller provides lock control output. For a lock which should be open when being energized and be closed 1# Controller 2# Controller 8# Controller
when being de-energized, the “COM” and “ NO” terminals should be used. For a lock which should be open when being
de-energized and be closed when being energized, the “COM” and “ NC” terminals should be used.

Notes:

1) The auxiliary input may be connected to infrared body detectors, smoke detectors, gas detectors, window magnetic alarms, wireless exit switches, etc.

2) The auxiliary output may be connected to locks, monitors, alarms, door bells, etc.

3) The auxiliary input and the auxiliary output is set with iAccess4.0.

4) GPRS, WiFi and the following items indicated with "*" are optional. Please contact our business representatives or pre-sale technical
support for ordering machines with GPRS and WiFi functions.
5) Recommend use of wires

A. Use 2-conducotor power cord

B. According to the port you connected, choose such as 8,10 conductor cord communication twisted-pair sensor cable (RVVP 8*0.5mm)

C. Use 2-conducotor lock power cord (RVV 2*0.75mm)

D. Use 2-conducotor switch or magnetic power cord (RVV 2*0.5mm)
