| Subject: | Re: AERA660 RS232 Output Test? |
Hi John,
1. Would I connect pin 7 (RS232) to the RS232 TX terminal and pin 1 (gnd) to
the RS232 GND terminal?
Pin 7 (TX) will be connected to the RX terminal on the breakout. The connections
on RS232 are typically connected in a complimentary nature. Transmit (TX) on
the source device will connect to Receive (RX) on the receiving device.
2. Would a USB port on the panel work to power the converter vs. a computer?
NO. Do NOT include the panel USB power.
The PCs USB port will power the converter. Only the power common (which is also
used as the signal common) is used / needed..
2a. It might be simpler to switch pins 7-9 on the output side of the d-sub and
re-set the 232 settings appropriately for the Aera to check.
YES!
Switching the output signals is a good way to evaluate the problem.
This assumes pin 8 (rx channel 1) is not connected beyond the db9.
This test would also assume the baud rate is the same on both channel 1 and 2 in
the aero. (Ive not looked into the configuration options for the aero to see
if this is even an issue).
Dan.
