3.1 DIP SWITCH S2 & S3

The Models 593/25F, 593/45, and 593/TB feature two eight-position Dip switches (S2 and S3). These switches are accessed by opening the plastic case by inserting a small flat blade screwdriver in the slot on either side of the case and twisting gently. Figure 1A, below shows Models 593/TB & 593/45 bottom view of the printed circuit board and the location of the dip switches. Figure 1B shows Model 593/45 bottom view of the printed circuit board and the location of the DIP switches

The Models 593/25F, 593/45, and 593/TB switches (S2-1 thru S2-8 & S3-1 thru S3-8) can be configured as either “On” or “Off”. Figure 2 shows the orientation of the DIP switches with respect to ON/OFF positions.

The switch is shown in the Off position.

3.1.1 Configuration DIP Switches Sets S2 and S3

The two eight-position Dip switches are used to configure the units for common asynchronous data rates, full or half duplex over 2-wire/4-wire twisted pair. 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.
