+5V is only available on Pin 1 when a jumper is installed on J4. Refer to section

3.1-Field Wiring

Connections

for the location of J4.

Serial port COM1 may be configured as RS-232 or RS-485. A jumper must be installed on J9 to
operate COM1 in RS-485 mode. Refer to section

Field Wiring Connections

for the location of

J9.

The differential receive and transmit signals are l/–Rx and +/–Tx respectively. Some RS-485
devices refer to the – side of the signal as A and the + side of the signal as B.

The following table provides a description of the function of each pin of the RJ-45 connector. In this
table a MARK level is a voltage of +3V or greater and a SPACE level is a voltage of –3V or less.

Pin

Function Description

1 5V

(Output)

This pin can be connected to the 5V power supply by installing a
jumper at J4 on the SCADAPack 32P.

2 -Rx

(Input)

The DCD led is on for a MARK level.

3 -Tx

(Output)

This pin is normally at a MARK level.
This pin is at a SPACE level when DTR is de-asserted.

4

GND

This pin is connected to the system ground.

5 +Rx

(Input)

The level is SPACE on standby and MARK for received data.
The LED is lit for a MARK level.

6 +Tx

(Output)

The level is SPACE on standby and MARK for transmitted data.
The LED is lit for a MARK level.

7

N/C

Do not connect this pin for RS-485 operation.

8

N/C

Do not connect this pin for RS-485 operation.

4.4.2

RS-485 Bias Resistors

The RS-485 receiver inputs on the SCADAPack 32P controller are biased to ensure that that received
data is driven to a valid state (space) when there are no active drivers on the network. The value of
these bias resistors is 4700 ohms from Ground to the –Rx input and 4700 ohms from +5V to the +Rx
input.
