OTT-2100 OSDP COMSET Configuration & Diagnostic Tool

Tony Diodato - Cypress President and CTO
Today, I’d like to talk about a new product from Cypress Integration Solutions. It’s an OSDP test and configuration tool called the OTT-2100, and it is designed to be a handheld, battery-operated device that will configure a peripheral device in the field or on the bench, as well as provide a means of diagnosing what’s going on in a very simple way.
What’s going on the bus between the access control panel and its peripherals. There are two modes. One is a listen mode and one is a COMSET mode, and I’ll talk about that in a second. The DIP switches actually implement the two configuration parameters that are vital to every peripheral device, that is the ID of the device as well as its baud rate.
And of course, that has to be set up the same way in the access control unit. So a lot of times you’ll get a brand new unit out of the box and you’re really not sure what the configuration is and it may require using some software which may involve a laptop and a cable or going to the access control panel and using another piece of software to try to configure the panel, which is a little bit difficult when it is an actual live installation.
So this device is meant to come along and provide that one feature, setting those communication parameters. So we have one that’s wired up right now. So it is in what I call an eavesdrop mode. It’s a diagnostic wiring. It’s in parallel with the twisted pair bus between the peripheral and the access control panel. So the panel has been configured to pull address 1 at 9600 baud.
In Listen Mode
So I’ve set the DIP switches for that configuration here on the COMSETTER, which is in the Quick Start Guide. There’s a simple table to to figure that out. So I’m going to put it in listen mode. And right now it’s not seeing any activity. Every once in a while you’ll see a flash. That’s a timeout, meaning the the panel has polled and not gotten a response.
So that’s pretty much confirming that the reader is not communicating. And of course, if we present a badge that’s been programmed into the panel, nothing happens. There’s no access granted. Now, we’ve got some convenience wiring here rather than watching me fumble through unwiring and probably breaking some wires or something. We just went ahead and put two connectors on it so we can flip it around.
Setting the address and baud rate
So now the communication is disconnected from the panel and we’re just talking to the peripheral device itself. Okay. So the DIP switches are set up for address 1 at 9600 baud. So I’m going to go ahead and flip it over to this, not knowing what its current configuration is. And immediately we get three green lights, one of them flashing.
The green lights are indicating that it’s successfully set the communication parameters and now it’s just in a constant polling mode, just looking for any communication errors. So it’s sort of like a bit error rate tester, you can actually see NAKs on there and timeouts. So it’s pretty steady, pretty solid communication. So now I’m going to plug that back into the access control panel and immediately we see on the panel the indication that communication is happening rather rapidly.
So there’s a constant poll and response between the reader and the panel. And if I present the same badge, I do indeed get an access granted. And likewise, if I go ahead and eavesdrop for address 1 at 9600, we do see activity. So the COMSETTER tool is verifying that, yes, there’s good communication going back and forth between the panel and the reader.
There you have it. It’s a nice little tool to have in your toolbox at all times. We even have a couple of situations where having multiple devices with already set up reader configurations, perhaps you’re always putting in two readers so you can have one set up for reader 1, one for reader 2 at the appropriate baud rate and just plug them in on the bench or in the field and quickly configure the readers.
Well, that’s it for today, and I hope this tool helps save money and make life a little easier for the installer.
