1.3 RS485 COMM supports 1200, 2400, 9600 and 19200 baud rate using 8 data bits and one stop bit. Parity is not
supported. Refer to Table 1.3 for Baud Rate switch configuration. Set S1 positions 6-7 for the desired Baud
Rate configuration.

9600 OPEN CLOSED
19200 CLOSED CLOSED
1.4 Set 100-ohm termination resistor (if required). Network termination is required if the unit is located at the
beginning or end of the network bus. Termination reduces unwanted reflections caused by data signal
propagation due to long wire runs. Refer to Table 1.4 for switch configuration. Set S1 position 8 for network
termination if required.

2.0 Messaging Format
2.1 The RS485 COMM utilizes the Edwards SigNet ASCII protocol for data messaging. Each unit is capable of
consuming and/or producing messages from the master controller. SigNet message format is illustrated
below.
<STX> <UA> <DDDD> <ZONE> <ETX> <CHKSUM>
<STX> The <STX> character has a value of 2 hexadecimal and is required at the start of
every message (1 byte).
<UA> Two byte ASCII representation of the hex Unit. Example - If unit address 0A is
chosen, the two byte <UA> data field would contain ASCII ‘0’ and ‘A’ written in
ASCII format as 0A. Valid data range is ASCII 00 - 1F.
<DDDD> ASCII data field. (4 bytes total). These bytes contain commands, tone/message
and timed sequence data.
