Analog Output Module

ICD 13—Standard Controller ICD-13/05 35 of 56

It is not a simple matter to get the card to execute an analog conversion, thus it is not

possible to test or calibrate the card without additional software.

14.0 Analog Output Module

There are two models of the Analog Output card, according to the voltage range

required at the output. A High Accuracy version of each model is also available but will

not be described here.

14.1 Description

The Standard Controller Analog Output modules are the VMIC VMIVME-4100.This

module has models with two output ranges, ±10 Volts (suffix -040) and 0 to +10 Volts

(suffix -140). The card is supplied with an Instruction Manual[17] which describes the

module and its connections, gives configuration and installation instructions including

calibration, describes the programming interface and VMIC’s warranty and repair pro-

cedures, and also contains full circuit diagrams and parts lists.

14.2 Installation

EPICS supports up to 4 of these cards, with no differentiation between the two different

versions. A diagram on page 5-5 of the Instruction Manual shows the locations of the

jumpers and switches, which should be set as shown in Table 26 on page 36.

The final address bits are set based on the card number as shown in Table 27 on page 36.

The P3 connector on the front panel provides all the analog output signals, along with a

ground line for each signal — the pin assignments are given on page 5-9 of the Instruc-

tion Manual. The connector itself is not a normal IDC format as it comprises 32 connec-

tions and the rows are spaced 0.2 inches apart. According to the manual, the cable
