2.8 Powerup
To begin operating the Serial488/4, plug the power cord into an AC outlet.
WARNING
The interface is intended for INDOOR USE ONLY.
Failure to observe this warning could result in
equipment failure, personal injury or death.
After plugging in the pow er cord, turn on the Serial488/4 by depressing the rear
panel power switch (Figure 2-1). All the front panel L EDs should light for
approximately two seconds w hile the Serial488/4 performs an internal ROM and
RAM self check. At the end of this self check all indicators should turn off except
POWER.
If you obtain the above response then your Serial488/4 is alive and w ell. If all
LEDs remain on, then a ROM error has occurred. If all LEDs (except the power LED)
flash continuously, then a RAM error has occurred. Try cycling the pow er to the
Serial488/4 to determine that the error is repeatable.
If the LEDs do not flash and the PO WER indicator does not remain lit, there may
not be any power supplied to the interface. In this event, check to make sure the AC
power is supplied to the unit. If the problem persists, refer to the Service Information
section of this manual.
2.9 Programming Examples
These examples use the IO tech Personal488 and the BA SIC Keyboard Controller
program listed in appendix D . The Keyboard Controller program allow s direct
communication with the Serial488/4 (or any IEEE device on the bus) and is the most
convenient method of exercising the Serial488/4
and becoming familiar with the
commands and their actions.
First, set SW1 for Dual Primary addressing mode and bus address 8. Connect an
IEEE cable from the Serial488/4 to the IEEE connector on the Personal488. Turn on
