6200 Installation Guide
Pre-installation Adjustments — Optional
Factory Settings May Be Sufficient (if so, skip this section)
• DIP Switches (Device Address Selection; Autobaud Feature): Device address is set to zero.
NOTE
: If you are connecting
multiple units in a daisy-chain or multi-drop, you can automatically establish the device address by using the
ADDR
command,
thereby eliminating the need to access the internal DIP switches. The factory default baud rate is 9600 (maximum setting).
• Jumper JU2 (Configuring the Programmable Inputs as Sourcing or Sinking): The factory configuration is that all of the general-
purpose programmable inputs (24 inputs on the
PROGRAMMABLE INPUTS
50-pin connector) source current; that is, they are
pull-up to the in5V supply through internal jumper JU2.

• Remove power before removing the 6200’s enclosure (unplug the AC power cord).
• Remove the screw-terminal connectors from the front panel and make sure the clips on the 50-pin
connectors are pushed inward so that they do not catch on the front panel.
• While handling the 6200 printed circuit assembly (PCA), be sure to observe proper grounding
techniques to prevent electro-static discharge (ESD).

To implement the Auto Baud feature:
Switch #4 ON = Auto Baud Enabled
Switch #4 OFF = Auto Baud Disabled (default)
The default baud rate is 9600. As an alternative, you can use
this procedure to automatically match your terminal's speed
of 1200, 2400, 4800, or 9600 baud.
1. Set switch 4 to ON.
2. Connect the 6200 to the terminal.
3. Power up the terminal.
4. Cycle power to the 6200 and immediately press the
space bar several times.
5. The 6200 should send a message with the baud rate
on the first line of the response. If no baud rate message
is displayed, verify steps 1-3 and repeat step 4.
6. Change switch 4 to OFF.
7. Cycle power to the 6200. This stores the baud rate
in non-volatile memory.
NOTE: If Auto Baud is enabled, the 6200 performs its auto
baud routine every time it is powered up or reset. The 6200
is only capable of matching 1200, 2400, 4800, and 9600
baud. Once the baud rate has been determined, the 6200
stores that baud rate in non-volatile memory; therefore,
Switch #4 should be set to the OFF position after the baud
rate has been determined.
