The performance parameters 1, interface: in accordance with the EIA RS - 232 and CCITT v. 24 asynchronous protocol 2, connector: use the DB9 connector on both sides 3, transmission modes: asynchronous, full duplex, transparent 4, isolation voltage: 2500 VRMS pulse or 500 VDC continuous 5, transfer rate: 300 BPS to 57600 BPS 6, power supply, power supply to the RS - 232port (TXD, RTS or DTR) 7, appearance size: 64 mmx33mmx17mm 8, weight: 30 g 9, the use of the environment: - 30 ℃ to 70 ℃, relative humidity of 5% to 95% Connection methods The DT-9011 protector directly concatenated from the original RS-232 device interface between, pay attention TO the DTE and the TO the direction of the DCE, in general, PC, multi-user card belongs TO the DTE device, a MODEM, terminal belongs TO the DCE device.So, if two DTE device should be used cross the RS - 232 cable is connected, when using the DT-9011 e, regardless of the DT-9011 in which one side, TO a side of DTE device, should be TO connect TO one side of the DCE cable. |
