Introduction

DS-1400/1800 Installation Guide Rev 05.12 Page 2 of 15 Essential Trading Systems Corp.

The DS-1400/1800 Media Gateway is a 4/8-port analog to IP device that provides full duplex
audio communication over a customer's existing network (recommended) or the internet in a 1
Rack Unit enclosure. The DS-1400/1800 utilizes Windows application software for secure
network connectivity and ETC’s Viper VoIP software powered by Twisted Pair’s WAVE software
as transport medium.

“E & M” Functionality

DS-1400/1800 Installation Guide Rev 05.12 Page 4 of 15 Essential Trading Systems Corp.

“M” Lead (Tx): Both the VG-1400 and VG-1800 have the “M” Lead option of adjustable time­delay PPuusshh TToo TTrraannssmmiitt ((PPTTTT)) ccoonnttaacctt cclloossuurree. The “M” Lead option becomes critical in
matching transmit delay to equipment key-up time. Each of the four channels has a dedicated
16 position adjusting switch (Figure H). Included on the back of the board is a label (Figure I)
showing the switch adjustment position to time delay correlation (Figure J). The PTT Dry
Contact is a solid state non-polarized Normally Open (NO) relay. Specification maximum values
are 100VDC max. Open; 150mA current and 8

Ω max resistance Closed.

“E” Lead (Rx): Only the VG-1400 has the option of requiring a switch TToo EEnnaabbllee RRxx or having

noise can be interpreted as an analog signal. Thus, having Rx disabled unless the VG-400
receives a viable switch signal avoids noise. Pair 3 is designated as “E” Lead Rx with Pin 3 as
Ground and Pin 6 as logic level +3.3VDC. Pulling or “Pinning Up” Pin 3 to Pin 6 is what enables
Rx to activate. The DS-1400 uses jumper JP1 (Figure J) to globally enable or disable this
feature.

• By positioning JP1 in “E & M” mode, the board

requires a switch signal TToo EEnnaabbllee RRxx.

• By positioning JP1 in “On” mode, which is the factory

default setting (Figure J), the board does not

switch signal and is AAllwwaayyss AAccttiivvee RRxx..
