Connector and signal
Conforming to EIA RS-232 and CCITTV2.4 standards. 2-3pin for data sending and receiving,7-8pin for RTS and CTS,4-1 pin for DTR and DCD, 6 pin for DSR and 5 pin for GND. RS-232 interface(TODTE): Connector: DB-25/9 hole-shaped connector to be used.
Signal: interior signal cables are separated.
Connection method
HK-7002 can be connected in series with between the serial connection cable of the previous RS-232 and the RS-232 interface, and either end is OK but you have to pay attention to the direction indicated by TO DTE or TO DCE. Generally speaking, PC user and multi-user are DTE devices, MODEM and terminal are DCE devices, however this general rule dose not apply to all situations. To decide DTE or DCE devices, you have to base your conclusion on the signal cable of your devices RS-232 interface. For example, it is DTE for the signal output from DB25 interface pin2, while its receiving input is DCE. Therefore, if crossed RS-232 cable isused to connect two DTE devices(e.g.terminal and multi-users), you have to connect the TODTE end to the device and TODCE end to the cable, no matter which side your HK-7002 is connected.
Application areas
Various kind of multi-user systems such as UNIX.
Protection of multi-user terminal and host.
Protection of satellite receiver.
Protection of multi-user cards.
Protection of ATM automatic teller machines connected with RS-232 devices without pubic grounding.
Protection of MODEM and routers.
