Transmission Parameters

• RS-232, RS-422, or RS-485 transmission standard
• Four baud rates (selected by the DIP switch):
– RS-232: 1200, 4800, 9600, 19,200
– RS-422, RS-485: 9600, 19,200, 38,400, 57,600
• Odd parity
• 1 start bit, 8 data bits, one stop bit
• Low-order bytes are transmitted before high-order bytes
The time-out period for Pinnacle units is factory set at 0.02 s (that is, no more than 0.02 s can
elapse between bytes or the unit will reset and begin looking for a new message packet). This
can be changed using Command 40.
The host computer must finish one transaction with a Pinnacle unit before it initiates another
one, either with the same unit or any other unit.
Note: If you have selected RS-232, the Pinnacle unit sends data through pin 2 (TXD.D). This
pin must be connected to to receive pin (RXD.D) on the host computer's PC serial
connector. The receive pin is normally pin 2 for a standard 9-pin PC serial port and
normally pin 3 for a standard 25-pin PC serial port.
Note: If you are using RS-422 or RS-485, the Pinnacle supply sends and receives data
differentially. Thus pin 6 (TR- or R-) and pin 7 (TR+ or R+) are either RS-485 transmit
and receiver lines or RS-422 receiver lines. Pins 8 and 9 are RS-422 transmit lines.

Using DIPs to Set the Pinnacle Unit's Network Address

A DIP switch provides the operator a way to set the network address of the Pinnacle unit.

SWITCH SETTINGS

The DIP switch (see Figure 4-12 on page 4-45 and Figure 4-13 on page 4-45) is used to set the
address for each Pinnacle supply in a multi-drop configuration. In units without master/slave
capability, the DIP switch is located on the rear panel of the Pinnacle supply next to the serial
(Host) port.
Note: On units equipped with a master/slave interface card this DIP is located inside the
unit on the master/slave interface card.
There are two types of DIP switch on Pinnacle supplies: "rocker" DIPs and "slide" DIPs (see
Figure 4-12 on page 4-45 and Figure 4-13 on page 4-45). Your supply will have one of these
types. While the switches on these DIPs are slightly different, they serve the same function.
Both DIPs contain eight miniature switches (here called "min-switches"). In all units, setting a
switch to the "up" position means setting it toward the numbers on the DIP, and setting a
