2.9.3 RS-485 Connections to a Modbus Device

2.9.3.1 4-Wire Connections

The 9009 and 9099's RS-422/RS-485 differential serial interface is a four-wire

interface with transmit (SD) and receive (RD) signal pairs with an optional

internal termination network on the receive pair. To interface the 9099 to a

4-wire Modbus device do not jumper the signal pairs together. Configure the

unit for full-duplex, RS-485 operation. Use the “SYST:COMM:SER:RS485

OFF” command to configure the firmware. The OFF setting causes the unit to

keep its serial transmitter on when not transmitting which keeps the receiving

devices from receiving noise and eliminates the need to terminating networks

at their end of the cable. The 9099’s TX pair goes to each slave device’s RX

input. Set jumpers W4 and W8 for RS-485 and move the W13 jumper to W7

FD position as directed in Table 2-3.

2.9.3.2 2-Wire Connections

To interface the 9009 or 9099 to a 2-wire Modbus device or RS-485 network,

the SD and RD signal pairs should be jumpered together internally as shown in

Figure 2-8 and the unit has to be configured for half-duplex, RS-485 operation.

Use the “SYST:COMM:SER:RS485 ON” command to configure the units.

The ON setting tristates the serial transmitter when the 9099 is not transmit-

ting which free’s the network for the Modbus device’s response. Add jumpers

W9-W12 to jumper the signal pairs together and to use the internal termina-

tion network. Set jumper W7 to HD. See Table 2-3 for the complete jumper

settings. Figures 2-8 through 2-10 show the two-wire RS-485 connections to

various Watlow controllers.

2.9.3.3 Internal Termination Network

Two-wire RS-485 networks need a termination network to bias the lines in the

‘mark’ state when neither unit is transmitting. This prevents the receivers from

inputting noise when nothing is being transmitted. The 9009 and 9099’s have

an internal termination network which is fine for cables up to 200 feet long.

For longer cables, use a termination network at each end of the cable. Insert

jumpers W11 and W12 to use the 9099’s internal termination network.
