Serial interface (standard HO90)

It is possible to select the transmission rates 300, 600, 1200,
2400, 4800 or 9600 Bauds by pressing the context sensitive
key (5). The other parameters are fixed:

• parity none
• 8 data Bits
• 1 stop Bit

RS232 interface  (option HO89)

The interface RS232 (HO 89) have the same possibility to
select transmission rates. It is also possible to change the
parity (even/odd/none), the width word (7 or 8 Bits) and the
number of stop bits (1 or 2).

IEEE-488 interface (option HO88)

With this menu, it is possible to modify the instrument address
on the IEEE-488 bus when the option HO88 is installed. The
address can be increased or decreased in autorized limits (1 to
30) by selecting one of the two context sensitive keys (5).

Display «Lcd»

The adjustment of the contrast and display light are selected
by pressing one of four context sensitive keys (5), corresponding
to « + » or « - ».

PREV. key

The previous menus is got by pressing the «PREV.» key  (3).

ON/OFF key

The output «RF OUT» (14) is active only if the «ON/OFF» key
(12) is pressed  and the «ON» led is lighted. When the signal
is  not active, the output is an open circuit.

RCL-STO keys

The instrument is equipped with an internal non-volatile memory
which stores all operational parameters in use  (frequency,
level, modulation ...) when the power is switched off. In
addition to this « current set-up» storage the instrument offers
the possibility to store 10 complete configurations, corres-
ponding to current state at different time.

After pressing the «STO» key (6), we get:

The current configuration can be stored by pressing  a numeric
key from 0 to 9.

After pressing the «RCL» key  (4), we get:

A configuration can be recalled by pressing  a numeric key from
0 to 9. That becomes the current configuration.

REMOTE OPERATION

Interfaces

The HM8134 may be equipped with one of the three following
interfaces:

• serial interface (HO90) which is the  default    equipment.
• RS232 interface (HO89) which is a special option.
• IEEE-488 interface (HO88) which is a special option.

The serial interface is a 9-pin connector ( DB-9, male connector)
on the rear panel.

Only three wire lines are connected inside:

• pin 2 as Txd (transmit data).
• pin 3 as Rxd (Receive data).
• pin 7 as Gnd (Ground).

Electric voltage on Rxd must be according to the RS232
hardware standard (+12/-12V max). This provides the capability
to communicate with any PC computer on COM1 or COM2
port.The communication protocol is an Xon/Xoff procedure
and operates as follows. Once the instrument has received a
commands line (refer to the definition below), it sends the Xoff
character (19 dec).

After all commands (in the received line) have been computed
and executed, it sends the Xon character (17 dec), making the
transmission of a new line possible. Commands are the same
for all interfaces (For more details about the options refer to
the corresponding manual).

When a remote command is received, the instrument displays
on the second line the following message:

The user may come back in Local mode by pressing the
context sensitive keys (5) just bellow the Local option (all other
keys are locked).

The user may lock all keys, by the command LK1 and in this
case the display becomes:
