Please follow the following steps. In case further assistance is
needed, contact your MicroScan program installer or support person.
Check the simple things first, i.e cables connected to back of computer and
converter box, converter box powered up (either by mains plug or plug pack
depending on type of converter).
Step 1. Station Power Applied.
The first step to perform is to confirm
that the power is applied to the station and the stations heartbeat light is
flashing.
Step 2. Communications: Station is RS232.
Check that the RS232 cable is
connected at the computer end. It is a 9 Pin or 25 pin gray connector, with a 6
pin cable connected.
Check the RS232 cable is connected at
the station end.
Check the RX, TX LED activity on the
station.
The RX LED on the station lights
up when the station receives data. It is normally OFF.
It is a dumb LED, it flashes ON
merely to indicate the arrival of a data signal.
The TX LED on the station lights up
when the station recognizes the data and sends a reply back.
Normally the RX and TX LED will flash together. If the station is not responding, only the RX LED will light up about once per second.
Step 2. Communications: Station is RS422 / RS485.
Check that the cable is connected
between the computer and converter box (IN2000-IS, 2100-IS, 2100-NS).
Check that the converter box has
power applied.
Check the RX, TX LED activity on
the converter box.
The TX LED lights when the computer
is sending data, the RX LED lights when the computer receives data.
Normally the TX and RX LED will flash
together. If the stations are not responding, only the TX LED will light up
about once per second.
Check the RX, TX LED activity on the
station.
The RX LED on the station lights
up when the station receives data. It is normally OFF.
It is a dumb LED, it flashes ON
merely to indicate the arrival of a data signal.
The TX LED on the station lights up
when the station recognizes the data and sends a reply back.
Normally the RX and TX LED will flash together. If the station is not responding or another station on the data loop is not responding, only the RX LED will light up about once per second.
