Enabling Pass-Through Port
About these procedures
The Digi One IAP has a second DIP switch on the top of the device for
enabling the pass-through port. When the pass-through port DIP switch is
enabled (ON), the DIP switch bank for EIA-232/422/485 operates for the
screw terminal port only. The screw terminal port is port 1. The DB-9 serial
port operates as the second port supporting only EIA-232.
The following are the procedures to enable the pass-through port as well
as diagnostic and troubleshooting tips for using the pass-through port.
Procedure: Enabling the pass-through port
1. While the unit is off, slide the pass-through switch to ON.
2. Power up the unit.
3. Install RealPort from the Access Resource CD under Software.
Note: If the unit has already been configured and you are adding the pass-through
port, reboot the unit after enabling the pass-through port. If RealPort is
installed before the pass-through port is enabled, the driver must be
reinstalled. Configure the pass-through port as the Master port. See
"Configuring a Serial-Connected Master: Other IA Protocol" on page 51.
Running Diagnostics
