Also, in most computer stores or online, you will be able to find or you may already have a
serial "LapLink" cable or "Null Modem" cable. These cables can be used to communicate
with the 1010P/DP systems.
If you purchased a 1010W model, you may have received the special connector used for the
RS-232 terminal in a packet included with your 1010W. This will enable you to construct the
appropriate cable for this flow meter type.
If you prefer to construct your own cable, the following conventions apply in the table:
● PC: Refers to an IBM compatible, DB-9 serial Com port.
● FUS1010 NEMA 4: Includes all models (N, DN, MN, FUE, EXCEPT those with "A1"
option). Termination is made to the 1010N-2 I/O Data Module. Flow meter end of cable is
un-terminated wire.
● FUS1010 NEMA 4 With "A1" Option: Flow meters that carry "A1" option have 1010N-7
module installed that houses a DB-9 connector for RS-232 communication.
● FUP1010 IP67: Includes all models (P/DP). Termination is made to the RS-232 port DB-9
connector. A DB-9 Female connector is needed to mate with the flow meter connector.
● FUP1010 WP: Includes all models (WP, WDP except energy meters). Termination is
made to the RS-232 port on the connector panel. A special cable terminal is required and
can be obtained from Siemens (Part #1015XWP).
● FUS1010X Compact: Includes all models (X, DX). Termination is made to the 1010X-8
I/O module Terminal TB2. Flow meter end of cable is un-terminated wire.
