3.0 CONFIGURATION The Model 590A/591A is equipped with two eight-position DIP switches that allow configuration to a wide range of applications. This section describes all possible configuration settings, including the factory default settings. 3.1 CHECKING THE DEFAULT CONFIGURATION The Model 590A/591A passes four optically isolated signals between the connected RS-232 DCE and DTE devices. The data signals, TD (pin 2), and RD (pin 3), have been dedicated and cannot be changed.
Before opening the Model 590A/591A’s case, check the default control signal settings (shown below). If the default configuration is correct, move to Section 4.0 of this manual. Otherwise, proceed to section “Setting the Internal Switches” to change the control signal settings. DCE Side DTE Side DTR (20) Control Signal 1 (20) DTR or RTS (4) (4) RTS CD (8) (8) CD or Control Signal 2 DSR (6) (6) DSR or CTS (5) (5) CTS *NOTE: Default control signals are shown above in bold italics 3.
The two sets of DIP switches on the underside of the Model 590A/591A will be referred to as S1 and S2. Figure 2 shows the orientation of DIP Switches S1 and S2 with respect to “ON” and “OFF” positions. ON ON 1 2 3 4 5 6 7 OFF 8 Figure 2. Close-up of DIP Switches Showing ON/OFF Positions Selecting the DTE Output Signals (DTR or RTS) Use Switches S1-1, S1-2, S2-1 and S-2-2 to connect either Data Terminal Ready (DTR - pin 20) or Request to Send (RTS - pin 4).
3.3 SELECTING THE DCE OUTPUT SIGNALS (CTS, DSR, OR CD) Use Switches S1-3, S1-4, S1-5, S2-3, S2-4, and S2-5 to connect either Clear to Send (CTS - pin 5), Data Set Ready (DSR - pin 6), or Carrier Detect (CD - pin 8. In the “Isolated” setting, the selected signal passes through Model 590A/591A isolated up to 2500VRMS.
4.0 INSTALLATION S/N 1 2 3 4 5 6 78 Model 590 RS-232 Opto-Isolater DTE DCE Connect to “DTE” Gaithersburg, Maryland The Model 590A/591A provides 2500VRMS optical isolation between a DTE and a DCE device. It plugs directly into the DTE and connects to the DCE by a short cable. No additional power is required in most cases. Refer to the diagram below and follow the instructions to install the Model 590A/591A. Connect to “DCE” Figure 3. Model 590A/591A DTE and DCE connector locations 1.
