Serial Port Configuration – Type 6

The Messenger has 4 serial ports (1-4). Port 1 is dedicated to the on-board cellular

modem.

CAUTION: Do not modify the parameters of Port 1.

Port 2 is set to RS485 by the factory. Port 3 is set to RS232 at the factory. NOTE: Not

all parameters shown below apply to every port.

Parameters for Serial Port Configuration

Parameter

Code

Reference

Description

Default

Mode

Range 0 – 7

0 = none

Port

Specific

Physical

Interface

Port 2 is the only port that has an RS485

transceiver. To enable RS485 for Port 2,

set this parameter to 1 and set

DIP

Switches

accordingly.
