There's only one image…

There is a command sent to the  "Hydraulic Operation Serial". The command message consists of 4 bytes (?), a leading "18" (looks like 2 chars/bytes but might be one char 0x18) and two more bytes representing the "Master Voltage Controller" value scaled to a 16bit value provided in big endian order (MSB first).

• The scaling and conversion to two bytes is overly complicated and could be simplified! (Additionally there should be some range check for the input value as you can easily overflow the allowed U16 range!)
• You don't need 3 VISAWrite calls to send just 4 (or 3) bytes, one call would be enough…
• The image doesn't seem related to the ADS1230 device…
