1.3 TERMINAL DESCRIPTION
The 2110 VS/DP Terminal is a ergonomically designed CRT display terminal
capable of communicating with the host VS (22V36, 23V96 and 25V36)
Asynchronous Controllers. This is accomplished via an enhanced RS-232-C type
port utilizing a simple asynchronous protocol. Included with the monitor is
the low cost serial keyboard designed to operate comfortably with Wang VS
software. The keyboard is the same as the one used with the Wang Office
Assistant equipment.
1. 3.1
LOW-PROFILE, COST.REDUCED SERIAL KEYBOARD
The Low-Profile, Cost Reduced Serial Keyboard (P/N 279-2050-US) is a
separate, detachable keyboard that contains 102 keys. It has 16 programmable
function keys, a HELP key, four cursor control keys (North Arrow, South Arrow,
East Ar~ow, and West Arrow) and a calculator style key pad. Standard word
processing Edit keys are also included (eg. Insert, Delete, Next, Previous,
Move, Copy etc.).
The keyboard assembly connects to the monitor via a 4-foot coil cord. This
assembly is designed with a lightweight, compact housing that provides
flexibility and convenient operation.

INTRODUCTION
1.3.2
LIGHTWEIGHT, MODUIAR MONITOR
The Monitor is compose<l of two halves, the monitor CRT assembly and the
b~se. It is divided by a semi-sphere between the two halves, so it can be
adjusted as the operator wishes. The monitor CRT section contains the display
drive board, the associated 12 inch CRT, and the switching power supply. The
power on/off switch and the video contrast control are located on the front of
the monitor CRT. The main logic board is within the base section while the
interface and keyboard connectors are mounted on the rear panel of the base.
The semi-sphere is designed for vertical and horizontal adjustments (up,down:
10 degrees each, left, right: 30 degrees each). This assembly is designed
with a lightweight, compact housing that provides flexibility and convenient
operation.
