5.Press Gor Dto scroll to odd, even, or no parity, respectively. Press EEto select the displayed parity.

6."Echo" now appears in the right display, with "On" or "OFF" appearing on the left display.

When Echo is "On", each character sent to the instrument over the RS-232 interface is "echoed" back to the host. If Echo is "OFF", commands are not echoed.

Press Dor Gto select echo "On" or "OFF". Then press Eto accept the displayed setting.

Autoprint and Memory Storage (RS-232)

Instrument measurements can be automatically sent to an RS-232 serial printer (Autoprint) or to internal Memory Storage. Both the Hydra Series II Data Acquisition Unit and the Hydra Series II Data Logger have the Autoprint function; only the Hydra Series II Data Logger has internal Memory Storage.

Note

During Autoprint operations, consider setting the instrument echo mode to "OFF". Although Autoprint does operate when echo mode is "on", the "OFF" setting prevents mixing of echoed command characters with autoprinted data.

Autoprint can be controlled from the front panel or over the RS-232 interface. Setting up storage into (and retrieving data from) memory in the Hydra Series II Data Logger can be controlled either from the front panel or over the RS-232 interface. Refer to Chapter 3 for front panel operation. The stored data cannot be viewed from the front panel; data must be requested through the RS-232 computer interface or listed on a printer.

Here are some rules to follow when using Autoprint and Memory Storage:

1.The RS-232 interface must be enabled before Autoprint can be enabled. (RS-232 is always enabled on the Hydra Series II Data Logger.)

2.Since the instrument does not print over the IEEE-488 interface, Autoprint is automatically turned off when you enable the IEEE-488 interface (Hydra Series II Data Acquisition Unit only.)

3.If you have selected Memory Storage (Hydra Series II Data Logger only), verify that the RS-232 interface is configured correctly before you upload the memory contents to a PC or printer.

Autoprint: Computer Interface Control

Autoprint can be controlled from the front panel or over the RS-232 interface. Refer to Chapter 3 for front panel operation.

Through the RS-232 interface, the PRINT_TYPE command can be used to set up Autoprint, and the PRINT command can be used to enable Autoprint. These commands follow a structure paralleling the front panel procedure. PRINT_TYPE selects destination (0 for Print Scans, 1 for Store Scans, or 2 for both) and type (0 for ALL, 1 for ALAr, or 2 for trAnS.) PRINT sets printing on (1) or off (0).

Autoprint: Output Format

The first line of an autoprint printout contains time and date values that identify when the scan was started. Time values include Hour:Minute:Seconds, and date values include Month/Year/Day. As an example, the following line is a valid start-of-scan time:
