Page 3: General Information
RS-422/RS-485 optical isolators, which guard your asynchronous data equipment from the hazards of ground looping. All Models have selectable Dip switch settings for RS-422/RS-485 applications. The Model 593 series provides 2500Vrms of isolation and supports data rates up to 115.2 kbps. Models 593/25F/45/TB are powered by an external +5V regulated power supply. -
Page 4: Dip Switch S2 & S3 Location
The following sections describe all the possible configurations. NOTE: When selecting any hardware configurations below, Switch S2 and Switch S3 must be set the same. 3.1.2 Full/Half Duplex S2-1 and S3-1 Switches S2-1 and S3-1 determine full duplex or half duplex trans- mission mode. -

Page 6: Installation
4.0 INSTALLATION Once you have properly set the configuration switches and jumpers, you are ready to connect Models 593/25F, 593/45, or 593/TB to your system. This section tells you how to connect the interfaces and how to operate your Model 593/25F, 593/45, or 593/TB. 4.1 CONNECTING TO THE RS-422 OR RS-485 INTERFACE To function properly, the Models 593/25F, 593/45, and 593/TB must have one or two pair of twisted pairs of metallic wire. -
Page 7: 2-Wire Connection Using
4.1.2 2-Wire Connection Using RJ-45 Most RS-485 devices employ a two-wire, half duplex configuration. When using this configuration, be sure to first set the Model 593/45 to half duplex mode by switching DIP switches and jumpers (refer to sec- tion 3.0 for this configuration)—then use only the transmit (XMT) pair as shown below 593/45 SIGNAL RS-485 SIGNAL... -

4.1.5 4-Wire Connection Using DB-25 Most DB-25 connectors on the Model 593/25F conform to EIA-530 interface standards. When connecting to the RS-422/485 devices which also conform to EIA-530 standards, your cable should have crossed over wiring, as shown below. Model 593/TB RS-485 SIGNAL DB-25 PIN...
