The TPG36x IOC controls a series a pressure gauges. The TPG36x device is very similar to the TPG26x device: the main difference is that the TPG36x uses different communication terminators, and uses RS485 as opposed to RS232.
The 361 is single gauge whereas the 362 is dual gauge. This means the two devices have a different protocol in regards to pressure return values. The 362 returns 2 values whereas the 361 returns 1 value.
The drivers protocol defaults to the 362 protocol by having a default value of N for the macro IS361. If you have a 361 device this will cause a protocol mismatch and the driver record will go into alarm.
To change this for a 361 device set IS361 to Y in globals.txt or in an IBEX configuration.
