K108 Serial I/o Module
Hello-I have an 8-relay serial I/O controller board I would like to use in a project (Kitsrus Model K108). This unit was designed to run off a PC via the serial port, and control the relays via simple text commands (ie 'N1' for relay 1 on, 'F1' for relay 1 off, and so on). It is not stand-alone programmable.I recently began working with the BS2, and would like to use it, as an embedded controller hooked up to the K108 I/O board in a project to control a series of 100W floodlights.I have been trying to use the SEROUT command, with a straight through cable connected from the BOE 9-pin, to the 9-pin on the K108. That should be easy.
I'm betting that your baud rate setting is not correct. Use the attached template for your tests - it allows you to set the baud rate based on the BASIC Stamp module that you're using; it also allows you to select True (which is what you need, I believe) or Inverted very easily.Using this template you should have a Baud definition like this:Baud CON T9600If I'm wrong and you need inverted mode, change the definition to this:Baud CON T9600 + Inverted▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔Jon WilliamsApplications Engineer, ParallaxDallas, TX USA.
