SECTION 11 BACNET PTP
PTP is used to connect two distinct BACnet networks so that information can be shared between the
networks. PTP uses an EIA-232 connection between two BACnet half-routers. This connection allows for
two different BACnet networks to speak to each other, even at different baud rates.
11.1 CONFIGURING THE AERCO XPC FOR BACNET PTP
1. Turn off the XPC's power.
2. Using the rotary switches, set the translator's address. Set the Tens (10's) switch to the tens digit of
the address, and set the Ones (1's) switch to the ones digit.
EXAMPLE: If the translator’s address is 01, point the arrow on the Tens (10's) switch to 0 and the
arrow on the Ones (1's) switch to 1.
3. Set the Comm Selector DIP Switches 1 - 8 for baud rate, port number, wiring, and protocol:
Set the Comm Selector DIP Switches 1 and 2 for the appropriate communications speed (9600,
19.2k, 38.4k, or 76.8k bps).
NOTE
USE THE SAME BAUD RATE FOR ALL DEVICES ON THE NETWORK
SEGMENT.
Baud Rate DIP Switch 1 DIP Switch 2
9600 Off Off
19.2 Off On
38.4 On Off
76.8 On On
• Set Comm Selector DIP Switch 3 to ON for Port 2.
• Set Comm Selector DIP Switch 4 (Port 1) will be set by the manufacturer.
• Set Comm Selector DIP Switch 5 - 8 for BACnet PTP.
The following example shows the DIP Switches set for 38.4k, Port 2, and BACnet PTP.
