Page 5: Setting The Dte/Dce Switch
The Model 222N is designed to be easy to use. There are no internal jumpers or DIP switches to set, so there is no need to open the case to configure the unit (you may need to open the case for wire connection—refer to section 4.0). -
Page 6: Installation
Once you have properly configured the DTE/DCE switch, you are ready to connect the Model 222N to your system. This section tells you how to properly connect the Model 222N to the RS-422 and RS-232 interfaces, and how to operate the Model 222N. 4.1 CONNECTION TO THE RS-422 INTERFACE The Model 222N supports data-only communication distances up to 4000 feet between itself and the RS-422 device. - Page 7 4.1.2 RS-422 CONNECTION USING RJ-11 OR RJ-45 The RJ-11 and RJ-45 connectors on the Model 222N's RS-422 side are pre-wired for a standard TELCO wiring environment. The signal/pin relationships are shown below: RJ-11 SIGNAL 1...GND* 2...RCV- 3...XMT+ 4...XMT- 5...RCV+ 6...GND In most modular RS-422 applications, it is necessary to use a "cross over"...
- Page 8 4.1.3 RS-422 CONNECTION USING TERMINAL BLOCKS If your RS-422 application requires you to connect two pairs of bare wires to the Model 222N, you will need to open the case to access the terminal blocks. The following instructions will tell you how to open the case, connect the bare wires to the terminal blocks, and fasten the strain relief collar in place so that the wires won't pull loose.
- Page 9 3. Strip back the insulation on each of the 2 twisted pair wires about .25". 4. Connect one pair of wires to XMT+ and XMT- (transmit positive and negative) on the terminal block, making careful note of which color is positive, and which color is negative. 5.
- Page 10 8. Place the 2 halves of the strain relief assembly on either side of the telephone wire and press together very lightly. Slide the assembly so that it is about 2 inches from the terminal posts and press together firmly. If your cable diameter is too small or too large for our strain relief, please contact our technical support.
