Before connecting or disconnecting the communication connector, be sure to turn OFF
this product. Otherwise, a fault may result.
The TSL-210 supports three different communication protocols, RS-232C and GP-IB, for
external communication with the TSL-210. In addition, LabVIEW software drivers are avail-
able. The control commands of each communication are the same; however echo back and
data retrieval methods are different. Explanations of the features and differences are outlined
below.
10-1-A Outline
GP-IB is an acronym for General Purpose Interface Bus. GP-IB utilizes a standard nearly
identical to buses such as HP-IB and IEEE-488. GP-IB is an easy-to-operate parallel interface
with excellent expandability to allow test set-ups to have connections to control computer,
measuring device, and other equipment. The GP-IB connection consists of 16 signal lines, 8
ground lines, and 8 signal lines—which are used as data lines, 3 for handshaking and 5 for con-
trol lines. Each connected device has one or two statuses out of three statuses, e.g. controller,
talker (sender), and listener (receiver). Generally the controller is a single system as only one
controller is allowed; however, it is possible to transfer the “control rights” to another device.
But since most computers today are controllers themselves, each device is designated as talker
or listener, and then data are sent and received and controlled on bus.
10-1-B How to Use
In GP-IB, it is necessary to set address per each device to be connected. Addresses are from 0
to 30, and each of all the devices connected should have an identical address.
Connect devices with GP-IB cable and turn the system on.
Note : Do not disconnect or connect a cable from and to devices connected with GP-IB
cable, do not short-circuit connector, and do not turn ON/OFF the devices. Otherwise,
action may be stopped, error may occur, causing a failure. In the event of trouble owing
to these causes, reset all the connected devices, and then activate the system once again.
When conguring a system, remove the unused device or unnecessary cable and return
to the original setup.
