to short together pin 4,6 and 8 in the plug connected to the COM-port for
proper operation.

VBT-325 is able to run with baud rates from 1200 to 19200 baud. By
default, the board automatically selects the baud rate of the connected terminal
when the user types <CR> after reset (refer to next chapter, "Power-on"). The
baud rate can also be manually changed by the command
' U t i l i t i e s / S e r i a l p o r t s ' .
Transparent mode
A convenient way of using the VBT-325 is to let the analyzer be inserted
between the terminal and CPU in your VMEbus system, so that the RS232
cable normally attached to the CPU board is instead connected to the Terminal
port on the VBT-325. Then, a one-to-one RS232 cable (with pins 2, 3 and 5
connected) can be connected from the Host port of the VBT-325 to the terminal
port on the CPU. (This cable can be purchased from VMETRO, part # 401-
TM-232). See figure below.
