Configuration of GWY-800-B (IBM Download)
User MUST download Project, PLC1 driver and HART in Gateway before installing any system using
Gateway. Gateway can accept drivers and configuration data on COM1 port. User needs a special IBM download
cable for downloading configuration in Gateway. All configurations can be downloaded only form Serial port (Port 1).
The other port is dedicated for HART.
If any change in the current / working project is made, user must download the changed project in Gateway.
Pin details of IBM download cable for GWY-800-B are as follows:
DB9 Male (Gateway) DB9 Female (IBM)

1.For downloading Firmware,drivers and project switch off the GWY-800-B unit.
2.Power ON the unit again.
For Master-Master mode:
OK LED is on at power on, it checks if the HART device is attached. If HART device is not attached then it goes in
IBM download mode for 10 sec. In IBM download mode OK LED flashes in slow mode.
While scanning HART device at power on unit will flash the OK LED in fast mode (approx. 15 seconds). So If user
want to configure the gateway, he/she should disconnect the HART device.
Also after checking the HART device connection, it continuously checks the if device is present on the PLC1/
COM1. Block execution will be started only after both the devices will be present.
For Master-Slave Mode:
OK LED is on at power on, it checks if the HART device is attached. If HART device is not attached then it goes in
IBM download mode for 10 sec. In IBM download mode OK LED flashes in slow mode.
While scanning HART device at power on unit will flash the OK LED in fast mode (approx. 15 seconds).
Only in IBM download mode firmware, drivers and project can be downloaded.
At power on, if OK LED does not glow indicating that the downloaded firmware, drivers or project CRC are not correct
or either of them is not present.
IMPORTANT NOTE:
AS GATEWAY HAS MULTIPLE SIGNALS ON ITS COMMUNICATION PORTS, IBM CABLE FOR GATE
WAY MUST HAVE ONLY THREE RS232 SIGNALS (TXD, RXD AND GND) AS MENTIONED ABOVE.
9-9 PIN CORE CABLE SHOULD NOT BE USED.
USER CAN FORCE GATEWAY IN THE IBM DOWNLOAD MODE.
1) Power on the gateway unit.
2) Short pins 3 and 4 of PLC1/COM1 port.
