38 AFP-200 PN 15511:H2 10/14/2002
Connection between the control panel and the PRN is via an EIA-232 interface. A
custom cable must be assembled for connection to the printer's EIA-232 port.

DB-25 Connections:
Connect TX (Pin 3) to TB4 terminal 1
Connect REF (Pin 7) to TB4 terminal 2
Connect RX (Pin 2) to TB4 terminal 3
Note: When using a DB-25 for Upload/Download connect a
jumper between pin 6 and pin 20.
DB-9 Connections:
Connect TX (Pin 2) to TB4 terminal 1
Connect REF (Pin 5) to TB4 terminal 2
Connect RX (Pin 3) to TB4 terminal 3
Note: If also using a DB-9 connector for
upload/download connect a jumper between pin 4 and
pin 6.
Plug the DB-9 or DB-25
connector into the EIA-232
port of the printer.
The EIA-232 printer interface may also be used
with EDP UL-listed equipment, such as personal
computers, to monitor the control panel for
supplementary purposes.
