CHAPTER 5: Operation
3. Temporarily short together the JP1 header pins 1 and 3 and re-apply DC
power.
4. A repeating sequence will occur. First, the Green LED (O) will flash, followed
by seven (7) flashes of the Amber LED (“C”).
5. The Green LED is the processor outputting the switch setup and operating
mode as serial data at 1200 baud, formatted as 8 data, no parity, 1 stop bit. To
view this data, connect a PC to the 9-pin D sub connector using 3 wires (pins
2, 3, 5) or a straight-through serial cable. Start a communications program
such as Procomm or HyperTerminal set to 1200, n, 8, 1. The next set of
Green flashes will put the modem configuration on the PC display.
6. The Amber LED flashes are the 6 positions of SW2 and the position of SW3. A
short flash means the switch is in the OFF position. A long flash means it is in
the ON position. For SW3, OFF is towards SW1 (4-wire) and ON is away from
SW1 (2-wire).
7. Compare the ON/OFF pattern to the setup tables for baud, handshake, # of
bits, and user operating mode.
8. Remove DC power and any JP1 connections.
9. Reapply DC power to enter your selected operating setup mode.
