ROC800-Series Instruction Manual 

Revised July-2017 

Communications 

5-11 

used to multi-drop units on a serial network over long distances using 
inexpensive twisted-pair wiring.  

EIA-422 (RS-422) drivers are designed for party-line applications 
where one driver is connected to, and transmits on, a bus with up to ten 
receivers. EIA-422 (RS-422) allows long distance point-to-point 
communication and the drivers are designed for true multi-point 
applications with up to 32 drivers and 32 receivers on a single bus.  

The default values for EIA-422/485 (RS-422/485) communication are 
19200 baud rate, 8 data bits, 1 stop bit, and no parity. The maximum 
rate is 57.6 Kbps. 

EIA-422/485 (RS-422/485) communication modules include LED 
indicators that display the status of receive and transmit activity. Refer 
to 

Tables 5-8

 and 

5-9

Caution

 

You can induce ground loops by tying commons from various modules 
together. 

 

 

EIA-422/485 (RS-422/485) communication provides EIA-422/485 (RS-
422/485) signals on the Comm3, Comm4, or Comm5 port, depending 
on where you have installed the module. Wiring should be twisted-pair 
cable, one pair for transmitting, and one pair for receiving. The EIA-422 
(RS-422) module uses four wires and the EIA-485 (RS-485) uses two 
wires for connectivity.  

5.8.1  EIA-422/485 (RS-422/485) Jumpers & Termination Resistors 

Four jumpers—J3, J4, J5, and J6—are located on the EIA-422/485 (RS-
422/485) communication module (see 

Figure 5-5

).  These jumpers 

determine the mode in which the module runs (RS-422 or RS-485) and 
if the module is terminated.
