Warning
EN
IFD8500 is an OPEN-TYPE device. It should be installed in a control cabinet free of airborne dust,
humidity, electric shock and vibration. To prevent non-maintenance staff from operating IFD8500, or to
prevent an accident from damaging IFD8500, the control cabinet in which IFD8500 is installed should
be equipped with a safeguard. For example, the control cabinet in which IFD8500 is installed can be
unlocked with a special tool or key.
EN
DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check
all wiring again before IFD8500 is powered up. After IFD8500 is disconnected, Do NOT touch any
terminals in a minute. Make sure that the ground terminal on IFD8500 is correctly grounded in
order to prevent electromagnetic interference.
FR
IFD8500 est un module OUVERT. Il doit être installé que dans une enceinte protectrice (boitier, armoire,
etc.) saine, dépourvue de poussière, d’humidité, de vibrations et hors d’atteinte des chocs électriques.
La protection doit éviter que les personnes non habilitées à la maintenance puissent accéder à
l’appareil (par exemple, une clé ou un outil doivent être nécessaire pour ouvrir a protection).
FR
Ne pas appliquer la tension secteur sur les bornes d’entrées/Sorties, ou l’appareil IFD8500 pourra être
endommagé. Merci de vérifier encore une fois le câblage avant la mise sous tension du IFD8500. Lors
de la déconnection de l’appareil, ne pas toucher les connecteurs dans la minute suivante. Vérifier que la
terre est bien reliée au connecteur de terre afin d’éviter toute interférence électromagnétique.
Introduction

Calculation of length of data frame:
Length = Start bit + data length + parity bit + stop bit
Example: Data Length = 8 bits, None parity, stop bit = 1 bit, Length = 1 + 8 + 0 + 1 = 10
Termination Resistor
To terminate the cable is system dependent and is affected by the choice of the maximum cable length
and signal rate. The length of RS-485 network cable can be extended to 4,000 ft or 1.2km. It is
necessary to match the line impedance of network to avoid signal distortion by adding to termination
resisters on both ends of RS-485/RS-422 network cable.
Hints for using termination resistor:
a. The longer the transmission cable, the worse the signal quality.
b. Two transmission resistors are recommended to install on both ends of the main cable on the
RS-485/RS-422 network. It is not necessary to add termination resistors on each node in the same
network.
c. If the transmission wire of RS-485 uses 1.2km AWG#24 twisted pair cable, we recommend you
use 120Ωresistor.

Operation
1. LED display:
a. Green LED On: Power on but no data transmission.
b. Red LED flashing: Data is being transmitted from RS-485/RS-422 to RS-232 port.
c. Green LED flashing: Data is being transmitted from RS-232 to RS-485/RS-422 port.
2. Notes for data transmission on RS-485:
The RS-485 allows for multiple drivers and receivers on single line, facilitating half duplex
communication. Before sending data to RS-485 bus line, make sure that there is no data
transmission on the bus; otherwise you will lose the data.

例如:資料位元長度 = 8 位元,無同位位元,停止位元長度 = 1 位元
則資料長度 = 1 + 8 + 0 + 1 = 10
終端電阻
當長距離傳輸時,傳輸線的阻抗及電容效應會造成信號的失真與延遲,此時則必須在兩條傳輸線間加入
終端電阻,使阻抗能匹配。
使用終端電阻原則為:
a. 傳輸線過長造成信號傳輸接收不良時。
b. 終端電阻只需接在同一網路點的首端及末端,其餘裝置則不用,如圖例。
c. 1.2 公里雙絞線建議使用 120Ω終端電阻,實際使用仍必須視傳輸線的規格及長度決定。
