GATEWAY COMMUNICATIONS MANUAL

If the integrator attempts to communicate to the translator but does not get a response, make sure

the translator is set as a BACnet MS/TP (m) master. The BACnet software asks the
translators, “Who Is?” This is to auto-locate devices on the network. Only translators set as
masters will answer this request.

See SECTION 16 for the BACnet Protocol Conformance Statement.

14.4 BACNET PTP

Verify BAS and translator settings:
1. Both set to speak BACnet PTP.

• Comm Selector DIP switches 5, 6, 7, and 8
• By getting a Modstat of the translator through the BACview. Hit the “FN” key and the ’.’ key at the

same time. Scroll to the bottom of the page to the section entitled “Network Communications”
to view the active protocol and baud rate.

2. Both set for the same baud rate.

• Comm Selector DIP Switches 1 and 2
• Verify via the BACview by obtaining a Modstat

3. BAS configured to speak 2—wire EIA--485 to the translator.

4. Both set to 8 data bits, No Parity, and 1 stop bit.

5. Rotary address switches set for the translator’s unique slave address.

6. Proper connection wiring.

7. BAS reading or writing to the proper BACnet objects in the translator - download the latest points list

for the translator to verify.

8. BAS is sending requests to the proper BACnet device instance of the translator.

9. Present the BAS company with a copy of your translator's BACnet PICS so that they know which

BACnet commands are supported.

See SECTION 16 for the BACnet Protocol Conformance Statement

14.5 N2

Verify BAS and translator settings:
1. Both set to speak N2.

• Comm Selector DIP Switches 3, 4, 5, and 6
• By getting a Modstat of the translator through the BACview. Hit the “FN” key and the ’.’ key at the

same time. Scroll to the bottom of the page to the section entitled “Network Communications”
to view the active protocol and baud rate.

2. Both set for 9600 baud rate.

• Comm Selector DIP Switches 1 and 2
• Verify via the BACview by obtaining a Modstat

3. BAS configured to speak 2—wire EIA--485 to the translator.

4. Both set to 8 data bits, No Parity, and 1 stop bit.
