Each slot accepts one scanner card. There are a total of 10 slots.
The serial output connector is a female BNC connector that provides
connection to another Model 706 for a daisy chain configuration.
The alarm function of this female BNC connector outputs a pulse when the
programmed alarm time is reached. The serial in function is used in a
daisy chain configuration where serial in is connected to the serial out of
another Model 706.
This female BNC connector outputs a pulse at the completion of the pro-
grammed channel settling time.
This is a female BNC connector that initiates the selected scan mode upon
receiving the proper signal pulse.
The digital I/O port consists of 16 digital input/output lines along with four
lines that are +5V and IEEE common.
This standard connector provides connection to the IEEE-488 bus.
The line power fuse provides protection for the AC power line input and is
rated as shown in Table 2-l.
The line power receptacle mates with three wire line cord and applies the
line power to the instrument.
2.5.3 Basic Front Panel Operation
This section provides the information necessary for basic
front panel operation of the Model 706. There are a number
of steps to follow in order to get the Model 706 ready for
scanning operation. These steps are as follows:
1. Install the desired scanner card(s). Refer to paragraph 2.2.2
for information concerning the installation of the scanner
cards into the Model 706.
2. Select appropriate line voltage. Refer to Section 5
Maintenance for information concerning the selection of
appropriate line voltage and proper fuse rating.
3. Turn on the Model 706. The instrument then goes through
the power up sequence that is described in paragraph 2.3
