Encore TWC-703 Adapter
3.1
Normal Mode
When you use the TWC-703 Adapter in Normal Mode, two channels of Clear-Com Partyline are
converted to TW. You have the option to use an external PSU (453G023) to inject power to the
TW output and reducing power draw from the systems main station or power supply.
Note:
The optional PSU is not included with the TWC-703 Adapter, and must be ordered separately.
A typical system connection example is given below.
3.1.1
To connect and operate the TWC-703 in Normal Mode:
1. Connect the required two channels of standard Clear-Com intercom lines to the female
Channel A and Channel B connectors .
2. Connect the TW remote intercom station to the male TW two-channel output connector.
3. Adjust the call signal translation settings as required. These switches enable/disable the
Call Translation between TW and Clear-Com. Disabling the call translation switches is only
necessary if one channel is sent through multiple TWC-703 Adapters.
Note:
RS703 Beltpacks must be configured for RTS™-TW using DIP switches.
Note:
To operate multiple TWC-703s in parallel on the same channel, only one TWC-703
should have call translation enabled for the channel. All other TWCs should have
call translation disabled. When two, or more, TWC-703s are connected to the same
intercom channel with Call Translation enabled, a call signal feedback loop will be
generated within the system. To solve this condition ensure only one TWC-703
performs call signal translation on an intercom channel.
Note:
Under rare operating conditions, internal jumper switches J8 and J9 allow configuration of auto-
termination. See
Internal Configuration on page 15
Note:
Under rare operating conditions, internal jumper switch J10 allows the configuration of RTS
Compatibility Mode. See
Internal Configuration on page 15
Note:
The TWC-703 adapter contains an automatic current limiter and reset circuit.
