ELOE00XZKE001 Introduction RS-232 is the interface with asymmetric signals. Maximum load capacity can be 2500pF and equates to c.50m typical twisted-pair cable. The asymmetric signals are not ideal to eliminate the influence of zero potential differences of terminal equipments (TE and/or DTE). The TE and neutral potentials have to be the same hence the RS-232 interface is intended to the point-to-point connection for 15m distance. -

Page 5: Power Supply Connection
ELOE00XZKE001 Power Supply Connection The converter contains two isolated parts that have to be supplied from two supplies isolated from each other. The RS-232 interface circuit is supplied from the TE signals. The TE has to supply at least one of TxD, RTS and DTR signals. The power take-off does not exceed c.3mA. -

The converter use is not allowed in lines exposed to the atmospheric electricity effects. Testing If interconnected properly, both diodes light up on each modem. Any simple communication test can be used (terminal emulator, …). -
