10. Remote commands from a PC
Transmission parameters :
Description of remote commands
ADD+ channel number : select the channel number and data sending. (ADD1 ♪)
ADN+ channel number : select the channel numberwithout data sending. (ADN1 ♪)
PGM C+ channel number: Memorize the maximumnumber of channel to be used. (PGM C4♪)
PGM K+ function number :Memorize the button key function. (PGM K3♪)
PGM F+ function number : Memorize the foot-pedal function. (PGM F2♪)
SCA a-z : Allows ascanning in simplex mode and data sending
fromchannel « a » to channel « z ». (SCA 1-4♪)
SCAD a-z: Allows a scanning in duplex mode and data sending
fromchannel « a » to channel « z ». (SCAD1-4♪)
VER: Display the softwareversion of D104-PC(VER♪)
Note : The character ♪is the ASCIIcharacter (13) = (CR) carriage return
This character is necessary if he is not included into the communication software.
Other remote commands
The remote commands are generally used with the duplex cables and duplex instruments
except the remote command CLE (Clear). This remote command allows the initialization of
min, max, delta on the following simplex instruments : S233 analog, S234.
For the duplex cables with duplex instruments, all remote commands according to the instruments
used are available. (See User’s manual of the instrument)
Mixing simplex and duplex cables.
Mixing simplex and duplexcables are not allowed.If you use simplex and duplex instruments,
please use duplexcables only.

11. Additional power supply « Booster »
In case of connecting more than 4 mini-dial gauges S233/S234, the using of a « Booster »
additional power cable is necessary for the unit D104-PC/ D104.
This ensures a good level of power supply on all gauges.
This additional “Booster” gives a considerable advantage, indeed it supplies all instruments
S233/S234 connected to a D104-PCand D104, which allows individual powersupply to these
instruments. (Not loosing the offsets).
