UTAH SCIENTIFIC PARTY LINE CONNECTION USING UDI−1B

The VM 3000 can be connected to a Utah Scientific Party Line through a UDI−1B Universal Data Interface (see Figure 2−36).
Some UDI−1B units are equipped with a 9−pin RS−422 port; others are equipped with a 25−pin RS−232 port. Either type can
be used.

The protocol for the UDI−1B port must be set at: 9600 baud, 7 data bits, even parity, and 2 stop bits. The UDI−1B must be
equipped with software version 81.4 or later. The UDI−1B “AUX” rotary switch needs to be set to “E” for “PL−160 Mode”
and to enable all mode commands. Refer to the UDI−1B manual for detailed procedures.
