POWER UP PROCEDURE
1.
Connect your cable to the DB-9 connector.
2.
Restore 24VAC and battery power to the controller.
3.
The status light on the 10A17 should be blinking once per second.
4.
When the 10A17 receives information from the connected system, the RCV LED will flash.
5.
When it transmits information back, the XMIT LED will flash.
Using the RS-232 connector (DB-9)
1.
RS-232 is specified for 50 feet or less. Although longer distances are usually not a problem, HAI makes no representation that
RS-232 will work over 50 feet.
2.
To fully test the 10A17 Serial Interface, connect it to a PC running HAI Model 1105 or 1106 PC Access Version 1.5 or later,
using a data transfer cable. Set PC Access to 9600 baud under
Configure | Modem
. When connected to PC Access, you can
perform all PC Access functions at high speed due to the 9600 baud connection provided by the 10A17.
3.
Connect the 10A17 Serial Interface to the final application system and check it out according to instructions provided with it.
4.
Be sure that nothing is connected to the RS-485 connector.
Using the RS-485 connector (A and B)
1.
RS-485 has the advantage of operating over greater distances: up to 1000 feet.
2.
The RS-485 connector operates in parallel with the RS-232 connector. Only one may be in use at a time.
3.
To use RS-485 connections, connect A and B of the 10A17 Serial Interface to A and B of the connected system.
4.
Be sure that nothing is connected to the RS-232 connector.
5.
No jumper settings or changes are required to use the RS-485 connections.
