Page 3: Ce Notice
The Model 1004ABRC can handle up to 50 terminal drops in a multipoint polling environment. Using transitions on the data line to handle line contention, the Model 1004ABRC can be used in environ- ments that need multi-port bus contention, but do not have control sig- nals such as RTS or DTR. -
Page 4: Configuration
Figure 1. Model 1004ABRC Card, showing location of configuration switches. Each of the DIP switches on the Model 1004ABRC function card is a 4-position switch. Figure 2 (below) shows the On/Off orientation of these switches. Use a small screw driver or similar instrument to set each individual switch. -

The “intermediate” setting is useful in half-duplex environments where the receiving device does not respond well to the “high” setting. S2-3 and S2-4: 2-wire/4-wire Modes Model 1004ABRC is in 2-wire or 4-wire operating mode. Note: 2-wire mode is half-duplex only. 3.1.2 SWITCH SETTINGS - MODEM “B”... - Page 6 High (16K Ohm typical) S3-2: RTS/CTS Delay The setting for switch S3-2 determines the amount of delay between the time the Model 1004ABRC “sees” RTS and when it turns on CTS. Note: RTS/CTS Delay setting should be based upon trans- mission timing.

Page 7: Rear Card Configuration
3.2 REAR CARD CONFIGURATION The Model 1004ABRC has two interface card options: the 1Q11 (which comes equipped with two RJ-11 ports and two RJ-45 ports) and the 1Q45 (which comes equipped with four RJ-45 ports). Figure 3 (below) illustrates these two different rear interface options. -
Page 8: Installation
DTE as DSR or RI (JB6 & JB7) Because this rear card is designed to function in more applications than the Model 1004ABRC, this jumper must be installed only in one position. Place the jumper across pins 1&2 so that the terminal (DTE) sees DSR as high when the DTE raises DTR. -
