4.2.2 RS-422 Sub-Channel Connections

Similar to the Model 305X, the Models 305X-422 Series multiplex and de-multiplex signals from four or six, or eight EIA-422 devices. EIA-422 devices may use D-Sub 25, D-Sub-9, RJ-45 or another connector type to transmit and receive data and operate flow control.. As with the Model 305X, you will need an adapter cable to make the proper connections. Figure 5, below, shows the pin assignments on the RJ-45 sub-channel modular jack on the 305X-422 Series.

Figure 5: Model 305X-422 RJ-45 Sub-Channel Pin Numbers

The diagrams below show the pinning of two RS-422 patch cables: DB-25 (RS-530) to RJ-45 and DB-9 (RS-449) to RJ-45. Because RS- 422 is a balanced interface, you should always use twisted pair wire for RS-422 cable (See Appendix B). Using low capacitance twisted pair cable between 19 and 24 AWG, you should be able to attain sub- channel distances up to 1000 ft. Please be careful to observe the correct wire pairing as shown below.

4.2.3 Extending RS-232 Sub-Channel Distances

You can also multiplex signals from sub-channel devices that are located more than 50 feet away from the Model 305X. Use a Patton Model 305X-422 with a Patton Model 222N RS-232 to RS-422 converter (see Appendix C for specific model numbers).

As Figure 6 below illustrates, the Model 222N replaces the modular to D-shell converter at the device end. This set-up allows sub-channel cable runs up to 1000 feet over two twisted pair wire. Call Patton Technical Support at for more information about the Model 222N.

4.2.4 Flow Control Requirements

All versions of the 305X Series accomodate flow control. Flow

control is a method whereby devices that process data more slowly (i.e. printers) can request faster processing devices (i.e. PCs) to temporarily stop and then restart data transmission. This gives a slower processing device the ability to clear its receive buffer to accept additonal data. All versions of Model 305X operate with software flow control. Models 3054AR and 3056AR may also operate with RTS/CTS (hardware) flow control.

Software Flow Control

The Model 305X Series is transparent to software flow control method on the sub-channel ports. Both sub-channel devices must be set to XON/XOFF or ACK/NAK or any other end-to-end software flow control method. The Model 305X simply passes the software flow control parameters through from end-to-end without modification.
