3.4.5 Long distance connection (RS-422, RS-485)
RS-422 and RS-485 serial protocols are recommended for longer 
distance serial connections between the PC and GC System (i.e., 
distances greater than the 50 feet).
To connect your PC to one of the internal Model 700 RS-422/RS-485 
serial port jacks:
1. Obtain the following equipment:
? An asynchronous line driver (or interface device) with RS-232 
input and RS-422/RS-485 output. See Appendix A for example 
brand and model.
? Shielded, computer-grade, twisted pair cable (to connect the 
asynchronous line driver device to the GC).
? A straight-through serial cable (to connect the PC to the line 
driver).
2. Connect the straight-through serial cable from the PC serial port 
to the RS-232 serial port of the line driver device. Then connect

the twisted pair cable to the RS-422/RS-485 serial port of the line 
driver.
3. Configure the line driver for data communications equipment 
(DCE) operation. See Appendix A for an example configuration.
4. Access the GC FTB (see Figure 3-20 in "Section 3.4.2: Preparing for 
serial connections").
5. Choose an available serial port on FTB that is configured for RS422 or RS-485 serial protocol, and connect the twisted pair cable 
from the line driver. See Appendix A for example connection. Also 
see Figure 3-24 through see Figure 3-28 for a list of ports and 
terminals assigned for serial communications.
